NTP-D107 Inspect and Maintain the Air Filter

Purpose

This procedure explains how to inspect and maintain reusable air filters. It ensures that the air filter is free from dirt and dust, which allows optimum air flow and prevents dirt and dust from entering the shelf.

Tools/Equipment

Vacuum or detergent and water faucet, spare filter, pinned hex key tool

Prerequisite Procedures

None

Required/As Needed

Clean the filter every three to six months. Replace the air filter every two to three years.

Onsite/Remote

Onsite

Security Level

None

Warning! Do not reach into a vacant slot or chassis while you install or remove a module or a fan. Exposed circuitry could constitute an energy hazard. Statement 206

Caution! If you install the air filter below 15454E-CC-FTA, only filters with part numbers 700-23193-01 and 700-23194-01 can be used in this configuration.

Caution! Although the air filter can work with older fan trays if it is installed with either side facing up, Cisco recommends that you install it with the metal bracing facing up to preserve the surface of the filter. You must install the air filter with the metal bracing facing up with 15454E-CC-FTA.

Note: Avoid cleaning the air filter with harsh cleaning agents or solvents.

  1. Verify that you are replacing a reusable air filter. The reusable filter is made of a gray, open-cell, polyurethane foam that is specially coated to provide fire and fungi resistance. NEBS 3E and later versions of the ONS 15454 SDH use a reusable air filter.
  2. If the air filter is installed in the external filter brackets, slide the filter out of the brackets while being careful not to dislodge any dust that might have collected on the filter and proceed to Step 9. Figure 15-1 illustrates a reusable fan-tray air filter in an external filter bracket.
  3. If the filter is installed beneath the fan tray and not in the external filter brackets, open the front door of the shelf assembly by completing the following substeps:
    1. Open the front door lock.
      Turn the key counterclockwise to unlock the door and clockwise to lock it. (The ONS 15454 SDH comes with a pinned hex key for locking and unlocking the front door.)
    2. Press the door button to release the latch.
    3. Swing the door open.
  4. (Optional) Remove the front door by completing the following substeps. If you do not want to remove the door, proceed to Step 5.
    1. Detach the ground strap from either the door or the chassis by removing one of the Kepnuts.
    2. Place the Kepnut back on the stud after the ground strap is removed to avoid misplacement.
    3. Secure the dangling end of the ground strap to the door or chassis with tape.
Figure 15-1: Reusable Fan-Tray Air Filter in an External Filter Bracket (Front Door Removed)

  1. Push the outer side of the handles on the fan-tray assembly to expose the handles.
  2. Pull the handles and slide the fan-tray assembly one half inch (12.7 mm) out of the shelf assembly and wait until the fans stop.
  3. When the fans have stopped, pull the fan-tray assembly completely out of the shelf assembly.
  4. Gently remove the air filter from the shelf assembly. Be careful not to dislodge any dust that might have collected on the filter.
  5. Visually inspect the air filter material for dirt and dust.
  6. If the reusable air filter contains a concentration of dirt and dust, replace the dirty air filter with a clean air filter (spare filters should be kept in stock) and reinsert the fan-tray assembly. Then, vacuum the dirty air filter or wash it under a faucet with a light detergent.
  7. Caution! Do not leave the fan tray out of the chassis for an extended period of time because excessive heat can damage the ONS 15454 SDH cards.

    Note: Cleaning should take place outside the operating environment to avoid releasing dirt and dust near the equipment.
  8. If you washed the filter, allow it to completely air dry for at least eight hours. Caution! Do not put a damp filter back in the ONS 15454 SDH.
  9. Replace the clean filter by completing the following substeps:
    1. If the air filter is installed in the external filter brackets, slide the dry air filter all the way to the back of the brackets to complete the procedure.
    2. If the filter is installed beneath the fan-tray assembly, remove the fan-tray assembly, and slide the dry/clean air filter into the recessed compartment at the bottom of the shelf assembly. Put the front edge of the air filter flush against the front edge of the recessed compartment. Push the fan tray back into the shelf assembly.

    Caution! If the fan tray does not slide all the way to the back of the shelf assembly, pull the fan tray out and readjust the position of the reusable filter until the fan tray fits correctly.

    Note: On a powered-up ONS 15454 SDH, the fans start immediately after the fan-tray assembly is correctly inserted.
  10. To verify that the tray is plugged into the backplane, ensure that the LCD on the front of the fan-tray assembly is activated and displays node information.
  11. Rotate the retractable handles back into their compartments.
  12. If you replace the door, also reattach the ground strap.
  13. Close and lock the door.
    Stop. You have completed this procedure.

NTP-D108 Back Up the Database

Purpose

This procedure stores a backup version of the TCC2/TCC2P (software) database on the workstation running Cisco Transport Controller (CTC) or on a network server.

Tools/Equipment

None

Prerequisite Procedures

None

Required/As Needed

Required. Cisco recommends performing a database backup at approximately weekly intervals and prior to and after configuration changes.

Onsite/Remote

Onsite or remote

Security Level

Maintenance or higher

Note: You must back up and restore the database for each node on a circuit path in order to maintain a complete circuit.

Note: The following parameters are not backed up and restored: node name, IP address, subnet mask and gateway, and Internet Inter-ORB Protocol (IIOP) port. If you change the node name and then restore a backed up database with a different node name, the circuits map to the new node name. Cisco recommends keeping a record of the old and new node names.

  1. Complete the "DLP-D60 Log into CTC" task at the node that you want to back up. If you are already logged in, proceed to Step 2.
  2. In node view, click the Maintenance > Database tabs.
  3. Click Backup.
  4. Save the database on the workstation's hard drive or on network storage. Use an appropriate file name with the .db file extension; for example, database.db.
  5. Click Save.
  6. Click OK in the confirmation dialog box.
Stop. You have completed this procedure.

NTP-D109 Restore the Database

Purpose

This procedure restores the TCC2/TCC2P software database, either partially or completely.

Tools/Equipment

None

Prerequisite Procedures

NTP-D108 Back Up the Database

Required/As Needed

As needed

Onsite/Remote

Onsite or remote

Security Level

Superuser only

Caution! E1000-2 cards lose traffic for approximately 90 seconds when an ONS 15454 SDH database is restored. Traffic is lost during the period of spanning tree reconvergence. The CARLOSS alarm appears and clears during this period.

Caution! If you are restoring the database on multiple nodes, wait approximately one minute after the TCC2/TCC2P reboot has completed on each node before proceeding to the next node.

Caution! TCC2P cards can be used in single IP address (repeater) and dual IP address (secure) mode. The secure mode has advanced features that affect database restore: A database from a secure node cannot be loaded on an unsecure repeater node. An unsecure database can be loaded onto a secure node but the database will follow the node characteristics (that is, become secure). A secure database cannot be loaded onto a TCC2; the restore is disallowed because the TCC2 card cannot boot in secure mode. For more information about the dual IP secure mode, refer to the NTP-D169 Set Up CTC Network Access. Also refer to the" Management Network Connectivity" chapter in the Cisco ONS 15454 SDH Reference Manual.

Caution! To avoid a node IP and secure IP ending up in the same domain after restoring a database, ensure that the node IP stored in the database differs in domain from that of the node in repeater mode. Also, after restoring a database, ensure that the node IP and secure IP differ in domain.

Note: The following parameters are not backed up and restored: node name, IP address, subnet mask and gateway, and IIOP port. If you change the node name and then restore a backed up database with a different node name, the circuits map to the new renamed node. Cisco recommends keeping a record of the old and new node names.

Note: ML-Series Ethernet cards must be reset after a database restore. For more information about restoring these cards, refer to the Cisco ONS 15454 and Cisco ONS 15454 SDH Ethernet Card Software Feature and Configuration Guide.

  1. Complete the "DLP-D60 Log into CTC" task at the node where you are restoring the database. If you are already logged in, continue with Step 2.
  2. Ensure that no ring or span (four-fiber only) switch events are present; for example, RING-SW-EAST, RING-SW-WEST, SPAN-SW-EAST, or SPAN-SW-WEST. In network view, click the Conditions tab and click Retrieve to view a list of conditions.
  3. If switch events need to be cleared, in node view click the Maintenance > MS-SPRing tabs and view the West Switch and East Switch columns.
  4. If a switch event is present, choose CLEAR from the drop-down list and click Apply.
    Note: A switch, if present, might have been caused by a standing Wait to Restore (WTR) condition.
    When a switch event is cleared, NO COMMAND appears in the column to indicate that the switch event is no longer in effect.
  5. In node view, click the Maintenance > Database tabs (Figure 15-2).
Figure 15-2: Restoring the TCC2/TCC2P Database

119609.jpg

  1. Click Restore.
  2. Locate the database file stored on the workstation hard drive or on network storage.
  3. Note: To clear all existing provisioning, locate and upload the database found on the latest ONS 15454 SDH software CD.
  4. Click the database file to highlight it.
  5. Click Open. The DB Restore dialog box appears.
  6. Caution! Opening a restore file from another node or from an earlier backup might affect traffic on the login node.

  7. If you need a complete database restore, check the Complete database (System and Provisioning) checkbox. Continue with Step 12.
  8. Note: Complete database restore may be used only on a node that is removed from the network, and does not carry live provisioning traffic. This operation needs to be done by a live operator onsite, and must not use a remote connection.

  9. If you need to restore only the provisioning database (partial restore), do not check the Complete database (System and Provisioning) checkbox.
  10. Click Ok.
  11. The Restore Database dialog box monitors the file transfer (Figure 15-3).
    Figure 15-3: Restoring the Database-In-Process Notification

    78893.jpg

  12. Wait for the file to complete the transfer to the TCC2/TCC2P card.
  13. Click OK when the "Lost connection to node, changing to Network View" dialog box appears. Wait for the node to reconnect.
  14. If you cleared a switch in Step 3, reapply the switch as needed.
    Stop. You have completed this procedure.

Security Level

Superuser only

Caution! Cisco strongly recommends that you keep different node databases in separate folders. This is because the reinitialization tool chooses the first product-specific software package in the specified directory if you use the Search Path field instead of the Package and Database fields. You might accidentally copy an incorrect database if multiple databases are kept in the specified directory.

Caution! Restoring a node to the factory configuration deletes all cross-connects on the node.

Caution! Cisco recommends that you save the node database to safe location if you will not be restoring the node using the database provided on the software CD.

Note: The following parameters are not backed up and restored when you delete the database and restore the factory settings: node name, IP address, subnet mask and gateway, and IIOP port. If you change the node name and then restore a backed up database with a different node name, the circuits map to the new renamed node. Cisco recommends keeping a record of the old and new node names.

  1. If you need to install or replace one or more TCC2/TCC2P cards, see the "DLP-D332 Install the TCC2/TCC2P Cards" task.
  2. If you are using Microsoft Windows, complete the "DLP-D244 Use the Reinitialization Tool to Clear the Database and Upload Software (Windows)" task.

The BITS-2 Out timing clock.

Status

Indicates the status of the timing clock.

INIT_STATE

The timing reference has not been provisioned. For an NE reference, this status appears just before the first provisioning messages when the TCC2/TCC2P is booting. Timing is provisioned to the internal clock of the node.

HOLDOVER_STATE

The clock was locked onto a valid timing reference for more than 140 seconds when a failure occurred. Holdover state timing is a computation based on timing during Normal state combined with the node's internal clock. The node holds onto this frequency until the valid reference is restored. This status appears for NE references only.

FREERUN_STATE

The node is running off its internal clock without any modification except the calibrated value to bring timing to 0 PPM. Free-run state can occur when a Force switch to the Internal clock is initiated, when all references fail without the 140 seconds of holdover data, or when only Internal timing references are defined. This status appears for NE references only.

NO_SYNC_STATE

A synchronization timing reference is not defined. BITS-1 Out or BITS-2 Out default to this status until an STM-N card is defined as its reference on the Provisioning > Timing tab. This status appears for external references only.

NE_SYNCH_STATE

BITS-1 Out and BITS-2 Out use the same timing source as the NE. This is displayed when NE Reference is selected for BITS-1 Out and BITS-2 Out in the Reference List on the Provisioning > Timing tab.

NORMAL_STATE

The timing reference is locked onto one of its provisioned references. The reference cannot be Internal or no sync state.

FAST_START_STATE

The node has switched references, but the reference is too far away to reach Normal state within an acceptable amount of time. Fast Start is a fast acquisition mode to allow the node to quickly acquire the reference. After it achieves this goal, the node progresses to the Normal state.

FAST_START_FAILED_STATE

A timing reference is too far away to reach in Normal state. The Fast Start state could not acquire sufficient timing information within the allowable amount of time.

Status Changed At

Date and time of the last status change.

Reference

Indicates the timing reference.

Three timing references (Ref-1, Ref-2, and Ref-3) are available on the Provisioning > Timing tab.

These options indicate the timing references that the system uses, and the order in which they are called. (For example, if Ref-1 becomes available, Ref-2 is called.)

Selected

Indicates whether the reference is selected.

Selected references are indicated with an X.

-

Facility

Indicates the timing facility provisioned for the reference on the Provisioning > Timing tab.

BITS-1

The timing facility is a building integrated timing supply (BITS) clock attached to the node's BITS-1 pins.

BITS-2

The timing facility is a BITS clock attached to the node's BITS-2 pins.

STM-N card with port number

If the node is set to line timing, the STM-N card and port provisioned as the timing reference.

Internal clock

The node is using its internal clock.

State

Indicates the timing reference state.

unlocked

The timing reference is operational.

locked

The timing reference is not operational.

Condition

Indicates the timing reference condition.

OKAY

The reference is valid to use as a timing reference.

OOB

Out of bounds; the reference is not valid and cannot be used as a timing reference, for example, a BITS clock is disconnected.

Condition Changed

Warning! Do not reach into a vacant slot or chassis while you install or remove a module or a fan. Exposed circuitry could constitute an energy hazard. Statement 206

Caution! Removing any active card from the ONS 15454 SDH can result in traffic interruption. Use caution when replacing cards and verify that only standby cards are being replaced. An improper removal (IMPROPRMVL) alarm is raised when a card reseat is performed, unless the card is first deleted in CTC. The alarm clears after the card replacement is complete.

  1. Complete the "DLP-D60 Log into CTC" task at the node where you want to replace the card.
  2. From the View menu, choose Go to Network View.
  3. Click the Alarms tab and complete the following substeps:
    1. Verify that the alarm filter is not on. See the "DLP-D227 Disable Alarm Filtering" task as necessary.
    2. Verify that no unexplained alarms appear on the network. If unexplained alarms appear, resolve them before continuing. Refer to the Cisco ONS 15454 SDH Troubleshooting Guide if necessary.
  4. Determine the active XC-VXL-10G, XC-VXL-2.5G, or XC-VXC-10G card. The ACT/STBY LED of the active card is green. The ACT/STBY LED of the standby card is amber.
    Note: You can also place the cursor over the card graphic to display a popup identifying the card as active or standby.
  5. If you want to replace the active card, you must first switch it to standby by completing the following substeps. If you want to replace the standby card, skip this step and continue with Step 6:
    1. In the node view, click the Maintenance > Cross-Connect tabs.
    2. In the Cross Connect Cards area, choose Switch.
    3. Click Yes in the Confirm Switch dialog box.
      Note: After the active XC-VXL-10G, XC-VXL-2.5G, or XC-VXC-10G goes into standby, the original standby slot becomes active. This causes the ACT/STBY LED to become green on the former standby card.
  6. Physically remove the standby XC-VXL-10G, XC-VXL-2.5G, or XC-VXC-10G card from the ONS 15454 SDH.
  7. Insert the replacement XC-VXL-10G, XC-VXL-2.5G, or XC-VXC-10G card into the empty slot.
    The replacement card boots up and becomes ready for service after approximately one minute.
    Stop. You have completed this procedure.

Security Level

None

Caution! Do not force an FTA into place. Doing so can damage the connectors on the fan tray and/or the connectors on the back panel of the shelf assembly.

Caution! 15454E-CC-FTA is compatible with Software R4.0 and greater.

Caution! As with the FTA3, the 15454E-CC-FTA Fan Fail LED on the front of the fan-tray assembly illuminates when one or more fans fail to indicate that a fan-tray assembly or AIP replacement is required. But the Fan Fail LED on the 15454E-CC-FTA will also illuminate when only one power source is connected to the chassis, and or any fuse blows. In such conditions, the Fan Alarm is triggered and the fans run at maximum speed.

Note: To replace the FTA, it is not necessary to move any of the cable management facilities.

  1. Review Table 15-3 to ensure that you have compatible components when replacing the FTA and note the alarms that will occur when an incompatible combination of hardware is installed.
    Note: If you need to determine the hardware that has been installed on a node, click the Inventory tab in node view.

Note: For a list of card and node default settings, refer to the "Network Element Defaults" appendix in the Cisco ONS 15454 SDH Reference Manual. To change card settings individually (that is, without changing the defaults), see Change Card Settings. To change node settings, see Change Card Settings.

  1. Complete the "DLP-D60 Log into CTC" task CTC at the node where you want to edit NE defaults.
  2. Click the Provisioning > Defaults tabs.
  3. Under Defaults Selector, choose a card type (if editing card-level defaults), CTC (if editing CTC defaults), or NODE (if editing node-level defaults). Click the node name (at the top of the Defaults Selector column) to display all available NE defaults in the Default Name column. To selectively display just the defaults for a given card type, for node-level, or for CTC-level, you can drill down the Defaults Selector menu structure.
  4. Locate a default that you want to change in the Default Name column.
  5. Click the Default Value column for the default property you are changing and either choose a value from the drop-down list (when available), or type the desired new value.
    Note: If you click Reset before you click Apply, all values will return to their original settings.
  6. Click Apply. (If it is unavailable, click in the Default Name column to activate the button.) You can modify multiple default values before applying the changes.
    A pencil icon will appear next to any default value that will be changed as a result of editing the defaults file.
    Note: Changes to most node defaults reprovision the node when you click Apply. Changes made to card settings using the Defaults Editor do not change the settings for cards that are already installed or slots that are preprovisioned for cards, but rather, change only cards that are installed or preprovisioned thereafter. To change settings for installed cards or preprovisioned slots, see Change Card Settings.
    Note: Changing some NE defaults can cause CTC disconnection or a reboot of the node in order for the default to take effect. Before you change a default, view the Side Effects column of the Defaults editor (right-click a column header and select Show Column > Side Effects) and be prepared for the occurrence of any side effects listed for that default.
  7. If you are modifying node-level defaults, a dialog box appears confirming whether you want to apply defaults for node level attributes that will override current provisioning. Click Yes.
  8. If you are modifying the IIOP Listener Port setting, a dialog box appears warning you that the node will reboot and asks if you want to continue. Click Yes.
Stop. You have completed this procedure.
