Cabletron Systems NB20E Manual De Usuario

 

When installation of the NB20E/NB25E Bridge is complete and the 
switches have been set, connect the bridge to the power source in the 
following manner:

1. If you have not already done so, plug the power cord (7, Fig. 3-3) into 

the power receptacle (6) located on the rear panel of the bridge.

2. Plug the power cord into a wall receptacle.

3. Turn the power switch, located next to the power receptacle, to the on 

position.

4. Observe the status of the ON-LINE, STANDBY, PORT 1 OK and 

PORT 2 OK LEDs. These LEDs will flash for approximately 10 
seconds as the bridge performs it's internal diagnostics.

When the bridge finishes its internal diagnostics, the LEDs should be 

in the following conditions:

•

ON LINE LED lit, indicating that the bridge is receiving power.

•

PORT 1 OK and PORT 2 OK lit, indicating that the ports have 
passed the internal loopback test and are now ready for 
transmission.

•

STANDBY on or off, depending on the bridge's position in the 
Spanning Tree Algorithim.
