Removing and Replacing the Power Supply Interface Assembly
The power supply interface (PSI) assembly is located under the top cover. You can see the PSI
from the rear of the chassis when the two power supply modules are removed.
WARNING! Ensure that the system is powered off and all power sources are disconnected
from the server prior to removing or installing server hardware.
Voltages are present at various locations within the server whenever a DC power source is
connected. This voltage is present even when the main power switch is turned off.
Failure to observe this warning can result in personal injury or damage to equipment.
CAUTION: Observe all ESD safety precautions while performing this procedure. Failure to
follow ESD safety precautions can result in damage to the server.
Removing the PSI Assembly
To remove the PSI assembly, follow these steps:
1. If rack-mounted, extend the server out from the rack until it stops. See “Installing Components
When the Server Is in a Rack” (page 114).
2. Power off the server. Disconnect all external cables.
3. Remove the server from the rack and place it on an ESD-protected work surface. See
“Removing the Server From a Rack” (page 115).
4. Remove the chassis top cover. See “Removing and Replacing the Top Cover” (page 123).
5. Remove the two power supply modules from the rear of the chassis. See “Removing a
Hot-Swappable Power Supply” (page 119).
6. Remove the fan control board including the PCI-X airflow guide and the CD/DVD optical
drive. See “Removing the Fan Control Board” (page 143).
7. From the rear of the server chassis, locate the four PSI mounting screws (M3 x 6mm long
pan T15/slot square cone stainless steel) and remove the screws and washers (flat MTLC
3.7mm ID 11mmOD stainless steel) (Figure 7-21).
