Trsm Installation

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.
