About Front Panel LED Issues on the Hardware Media Server
This section describes what to do if the LEDs on the front panel of the Hardware Media Server are off at all times, including during the power off and power on cycle.

The blades are not inserted correctly in the Cisco Unified MeetingPlace 3500 Series Media Server chassis, or a back plane pin is bent. |

About Ethernet Settings for the Hardware Media Server
We recommend the following Ethernet port settings:
| Audio Blade | Ethernet Switch Port | Result |
|---|---|---|
|
Auto-negotiate |
Auto-negotiate |
1000/Full |
| Video Blade | Ethernet Switch Port | Result |
|---|---|---|
|
Auto-negotiate |
Auto-negotiate |
1000/Full |
| Application Server | Ethernet Switch Port | Result |
|---|---|---|

1000 Mbps or 100/Full |

We do not recommend the following:
- Setting one device to auto-negotiate and setting the other device to a fixed configuration
Caution! Setting one device to auto-negotiate and the other device to a fixed configuration will often result in negotiation failure, where one side thinks it has a full duplex link and the other side thinks it has a half duplex link. This will result in intermittent non-specific failures which get progressively worse as the load on the system increases and can result in a complete service outage.
- Using 10 Mbps Ethernet
- Using half duplex Ethernet at any speed
- Using 10/100Mbps for MCU and EMP, nor any hard set values (MCU & EMP tested and certified only on Auto/Auto setting connected to 1Gb switchports)
Misconfigured Ethernet Ports
Problem: An Ethernet port is misconfigured. Symptoms include the following:
- Lost audio or video on a call
- Dropped calls
- Intermittent or no response to ping
- On an Audio Blade or Video Blade, intermittent failure to sign in using Telnet or web interface
- On the Application Server, intermittent failure to access the command line using SSH, or the Administration Center
- The following alarms:
- 180825 MCU blade is DOWN
- 180826 EMP blade is DOWN
- 180812 System has no audio capacity
- 180813 System has no video capacity
- 180810 System audio capacity is N ports; licensed for N
- 180811 System video capacity is N ports; licensed for N
Solution: Change the address settings by following the procedure in Changing Address Settings for the Hardware Media Server in the Configuring the Audio and Video Blades for the Hardware Media Server module.
Solution: Use the modifyTargetDevice command on the console of the blade to change the connection settings to match with that of the switch. See the Setting Initial Values for the Hardware Media Server module for information about using this command.
