Chapter 4 Maintaining the Sun Fire V40z Server 4-75
Individual power supply
6. 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 Assembly
7. 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.
