3.2.5Connecting The NB20E or NB25E To The Power Source

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.
