6-2 Dell PowerVault 51F 8-Port Fibre Channel Switch Installation and Troubleshooting Guide
Removing the Power Supply
To remove the power supply, you must perform the following steps.
CAUTION: There are two models of the PowerVault 51F switch. Model 2401
contains one power supply unit and model 2402 contains two. When
replacing a power supply unit on the 2401 switch, you must first turn off the
switch’s power. You do not need to turn off the power to the good power
supply on the 2402 switch.
1. Remove any external cabling attached to the power supply.
2. Pull out and lift up the metal handle from the top of the power supply unit; see
Figure 6-1.
3. Gently pull the unit out.

Installing the Power Supply
1. Slide the new power supply unit into its slot until the unit connects to the back
panel.
2. Lock the metal handle into the power supply by pushing the handle down and
sliding it up into place.
3. Reattach external cabling to the power supply.
The switch automatically runs power-on self-test (POST) on a 2401 switch
because all the power was off.
4. Check for error messages via Telnet.
