Dell PowerVault 775N (Rackmount NAS Appliance) - Manual (Page 50)

Replacing a Cooling Fan
NOTE: The procedure for installing each individual fan is the same.
1. Lower the fan into the retention base until the fan snaps into position (see Figure 6-1 ).
2. Replace the cover (see " Replacing the Cover " in "Troubleshooting Your System").
Power Supplies
The system includes one or two hot-pluggable power supplies.
Removing a Power Supply
NOTICE: The power supplies are hot-pluggable. The system requires one power supply to be installed for the system
to operate normally. The system is in the redundant mode when two power supplies are installed. Remove and replace
only one power supply at a time in a system that is powered on.
1. Squeeze the latch at the bottom of the power-supply handle.
2. Rotate the power-supply handle up until the power supply is released from the chassis (see Figure 6-2 ).
3. Pull the power supply straight out to clear the chassis (see Figure 6-2 ).
