Replacing an AC Power Supply
Warning
Never install an AC power module and a DC power module in the
same chassis.
Follow these steps to replace an AC power supply:
Step 1
Put on an antistatic wrist or ankle strap. Attach the strap to the ESD grounding
jack on the front of the chassis or to the bare metal surface of the chassis.
Step 2
If your system is configured with redundant power supplies, set only the power
switch
of the power supply you are replacing
to the standby position (
Figure 4
).
Caution
Do not power off both AC power supplies in a redundant system, or the system
shuts down and all data traffic stops. Power off only the AC power supply you
are replacing.
