Replacing a fan assembly
The model 8654 appliance server comes with six replaceable fans. The model 8672
appliance server comes with four replaceable fans.
Attention:
If a fan fails, replace it within 48 hours to help ensure proper cooling.
Complete the following steps to replace the fan assembly:
1.
Review the information in “Safety” on page vii.
2.
Turn off the appliance server and disconnect all external cables and power cords.
3.
Remove the cover according to “Removing the cover” on page 56.
4.
Determine which fan to replace by checking the LED at each fan; a lit LED
indicates the fan to replace.
Note:
The fan LEDs are illuminated by the Light Path Diagnostics circuit
(available on the xSeries 130 model 8654 only). For more information
about the LEDs and the Light Path Diagnostics circuit, see “Model 8654
Light Path Diagnostics table” on page 105.
5.
Remove the fan from the appliance server:
a.
Disconnect the fan cable from the system board.
b.
Lift the fan away from the appliance server.
6.
Orient the fan so that the air flow arrow on the side of the fan is facing or pointing
toward the rear of the appliance server.
Note:
Proper air flow is from the front to the rear of the appliance server.
7.
Push the replacement fan assembly into the appliance server until it clicks into
place.

Note:
When you start your appliance server after replacing a fan assembly, the
system-error light will either remain on or turn off. If the system-error light
remains on, you will have to turn off the appliance server to perform further
troubleshooting.
