Power Cycling the Phone
Use the power cycle with your System Administrator’s approval. Use power cycling only if the
basic or programmed reset procedure cannot be performed or does not correct the problem:
1. Unplug the phone and plug it back in.
The phone connection is re-established.
2. If power-cycling does not correct the problem, your System Administrator can perform a
more severe power cycle by unplugging both the phone and the Ethernet cables.

WARNING:
WARNING:
Because the type of power cycle mentioned in Step 2 involves reprogramming
certain values, Step 2 should only be performed by your System Administrator.
