5.2.1 Removing a Power Supply
1. Identify which power supply requires replacement (
FIGURE 5-3
).
FIGURE 5-3
Locating the Power Supplies and Latches
A lighted amber LED on a power supply indicates that a failure was detected. You
can also use the
showfaults
command at the
sc>
prompt.
2. At the
sc>
prompt, issue the
removefru
command.
The
removefru
command indicates if it is OK to perform a hot-swap of a power
supply. This command does not perform any action, but it provides a warning if
the power supply should not be removed because the other power supply is not
providing power to the server.
For example:
In this command,
PS
n is the identifier for the power supply you plan to remove,
either
PS0
or
PS1
.
3. Disconnect the power cord from the faulty power supply.
