Replacing a Power Supply
1
On a system with redundant power supplies, verify that both power
supplies are the same type and have the same maximum output power.
NOTE: The maximum output power (shown in watts) is listed on the power
supply label.
2
Slide the new power supply into the chassis until the power supply is fully
seated and the release latch snaps into place. See Figure 3-7.
NOTE: If you unlatched the cable management arm in step 2 of the previous
procedure, relatch it. For information about the cable management arm, see
the system’s rack documentation.
