Powering Off a ServerNet Cluster Switch

Powering Off a ServerNet II Switch

You can power off the ServerNet II Switch from either the UPS or the ServerNet II

Switch itself. If you are replacing a ServerNet II Switch or disconnecting the ServerNet

II Switch from the UPS for any reason, you must power off the ServerNet II Switch from

the UPS.

•

To discontinue the power available to the ServerNet II Switch from the UPS:

1. Press the Standby (middle) button on the uninterruptible power supply (UPS)

for three seconds until the Power-ON LED on the UPS becomes unlit. The

power to the ServerNet II Switch is discontinued, and the ServerNet II Switch

powers off.

Note. When powering off the ServerNet II Switch, wait 30 seconds before powering it back on

again so that the voltage can discharge fully and that proper initialization can occur. If you do

not wait 30 seconds, the ServerNet II Switch might come up in a non-operational state, and all

LEDs will be stuck on. Powering off and back on again after 30 seconds corrects the problem.
