Remove Power
102 Sun Server X4-4 Service Manual • October 2015
Remove Power
Powering the server from full power mode to standby power mode does not completely remove
power from the server. If you need to completely remove power from the server to perform a
cold reset or to place it in an non-powered state, you must disconnect the AC power cables on
the back of the server. Use this procedure to completely remove power from the server.
Before You Begin
“Power Modes, Shutdowns, and Resets” on page 103
1.
Place the server in standby power mode.
Use one of the power off methods. See “Powering Off the server” on page 97 .
2. If necessary, do the following:
a. Extend the server to the maintenance position.
b. Position the CMA.
3. Access the back of the server.
4. To remove power from the server, disconnect the AC power cables from the
power supplies.
This action completely removes power from the server.
5. If you are performing a cold reset, wait at least 60 seconds before connecting the
AC power cables to the power supplies.
For information about cold resets, see “Cold Reset” on page 104 .
