Power Cycling the Telephone
Use the power cycle only at the request of your System Administrator. Use power cycling only if
the basic or programmed reset procedure cannot be performed or does not correct the problem:
1. Unplug the telephone and plug it back in.
The telephone connection is reestablished.
2. If power cycling does not correct the problem, your System Administrator can perform a
more severe power cycle by unplugging the telephone and Ethernet cables.

WARNING:
Because the type of power cycle mentioned in Step 2 involves reprogramming
certain values, only your System Administrator can perform that step.
