Model 3120 RAS Getting Started Guide

Maintenance

Model 3120 RAS power supplies are hot-swappable, so a defective supply can be replaced without deactivating 
the RAS. Do the following to replace a malfunctioning power supply:

You will need a flat-tip screwdriver to perform the following 
procedure.

Figure 47. Captive fasteners and power cable retainer clip locations

1. At the malfunctioning power supply, rotate the power cable retaining clip (see figure 47) so it is no longer 

attached to the power cord.

2. Disconnect the power cable plug from the malfunctioning power supply.

3. Using a flat-tip screwdriver, loosen the two captive fasteners (see figure 47) enough so they are no longer 

connecting the power supply to the RAS chassis.

4. Carefully, pull the power supply from the RAS chassis until it is completely removed.

5. Place the failed power supply on a non-static surface.

Do not use the power cable retainer clip as a handle when 
removing the power supply from the RAS chassis. Failing to com-
ply with this caution could result in damage to the power supply.
