LED Activity

If the system is powered on, you can verify that your module is properly
installed by observing its LEDs. Follow the troubleshooting suggestions
below if LED activity is not normal.
Normal LED Activity
The following LED activity is normal during installation:
The Power/Unseat LED lights yellow briefly when the module is inserted far
enough into the chassis to use the inject/eject handles.
The Err LED lights yellow temporarily after insertion while the module runs
diagnostics.
The Power/Unseat LED lights green, indicating that the module is
powered on.
Once you have completed the installation procedure, only the green
Power/Unseat LED should remain lit.

Troubleshooting

If LED activity is not normal, check the troubleshooting suggestions
listed below.
If the Power/Unseat LED remains yellow, the module is not fully seated in
the chassis. Eject and re-insert the module as described in the installation
procedure starting on page 6.
If the Err LED remains yellow, contact 3Com Technical Support for additional
assistance.
If the Power/Unseat LED does not light green when the module is
powered on, contact 3Com Technical Support for assistance.
