Cisco Unified MeetingPlace, Release 6.x -- Replacing the Filter in the Power Supply Unit Fan (Cisco Unified MeetingPlace 8112 Only)
Note: The maintenance procedures in this section are for the Cisco Unified MeetingPlace 8112 only. The Cisco Unified MeetingPlace 8106 does not have a filter for the fan in the power supply unit.
You need to replace the filter in the power supply unit fan on a regular basis. The frequency of the replacement depends on how much dust is in the air. On average, you should replace the filter once a year.
In addition, if you see any of the following alarms, immediately check the power supply unit fan and its filter:
- 0x70034 (MAJOR) Temperature out of range.
- 0x700BB (MINOR) Power supply fan N is failing.
- 0x700C6 (MINOR) Power supply N cooling failure.
This section contains three procedures. Do them in the order listed to replace the filter.
Warning! Do not touch any of the exposed leads, terminals, or components. Hazardous voltages, capable of causing death, may be present in this product.
Note: CLI commands are case sensitive. For CLI command information, see the Command-Line Interface Reference.
To Remove the Old Filter in the Power Supply Unit Fan (Cisco Unified MeetingPlace 8112 Only)
- Pull out the top edge of the filter frame by using the metal tab in the top left corner of the filter.
- Pull the filter frame up at a slight angle to remove it by sliding it in between the power supply unit and the power supply unit handle.
- Remove the filter from the frame.
To Install a New Filter in the Power Supply Unit Fan (Cisco Unified MeetingPlace 8112 Only)
- Slide the new filter into the filter frame of the power supply unit fan.
- Place the filter frame between the power supply unit and the power supply unit handle. The correct orientation is when the metal tab on the filter frame is in the top left corner.
