Replacing a power supply
To replace a power supply, have the following items available:
•
A new power supply which you can order from Dell
•
A small flat-blade or Phillips screwdriver (NetIron MLX-4 only)
DANGER
The power supplies are hot swappable, which means they can be removed and replaced while
the device is powered on and running. However, Dell recommends that you disconnect the power
supply from its power source before removing and replacing the supply. The device can be
running while a power supply is being removed and replaced, but the power supply itself should
not be connected to a power source. Otherwise, you could be injured or the power supply or other
parts of the device could be damaged.
DANGER
The front panel of a power supply includes a handle that locks the power supply in the device.
This handle is a locking mechanism only and should not be used to lift and carry the power
supply. You may sustain physical injury or harm if you attempt to lift and carry a power supply
using the locking handle.
1.
Disconnect the power supply from the power source.
2.
Disconnect the power cables from the power supply.
3.
For a 4-slot device, use the screwdriver to loosen the two screws on both sides of the power
supply faceplate. Then pull the ejectors forward until the power supply disconnects from the
backplane.
4.
For an 8-slot or 16-slot device, pull up on the plunger on the faceplate and pull the handle
toward you until the power supply is released.
5.
Pull the power supply out of the device.
6.
Insert the new power supply into the empty power supply slot, using the guides provided on
either side of the slot.
