Individual power supply6. To re-install the power supplies (refer back to FIGURE 4-26):
Caution – You must open the power supply’s handle before you insert it into the
power-supply cage. If the handle is left closed, it will deform the metal to which it
latches.
Also, failure to open the power-supply handle only partially engages the power
supply’s connector, which can cause the power-reset sequence (PRS) code to enter a
failed state. If this happens, the system-fault LED on the front panel will blink twice
per second.
To recover a system in this bad PRS state:
1) Disconnect all AC power and reseat all power supplies.
2) Wait five minutes.
3) Reconnect AC power cords to all power supplies.
a. Open the power-supply handle to the fully open position, as shown in
FIGURE 4-26.
b. Insert the power supply into the power-supply cage and push it inward until it
stops at the backplane.
c. Push the power-supply handle closed until it locks into place.
Rear Fan-Cage Assembly7. Align the fan cage with the chassis and push down on both ends of the fan cage
until both retaining clips click securely into place and the fan-cage connector fully
engages with the motherboard connector.
Refer back to FIGURE 4-25.
8. Replace the main air baffle (refer back to FIGURE 4-20).
9. Before re-installing the cover on the server, check the routing of all cables for
obstructions.
