Customer Replaceable Unit (CRU) Procedures
User Guide—Sun Cobalt LX50 Server 5-11
Fan Module
The fan module is a single component. The individual fans that make up the module are not swappable. Should a fan
fail, the entire module will need to be replaced. A tab on the side of the fan module makes replacement of the module
tool-less and very simple. The fan module is not hot swappable. The server must be turned off before the fan module
can be replaced.
To replace the fan module, refer to Figure 69 and follow these steps:
1. Before removing the cover to work inside the system, observe the safety guidelines previously given.
2. Remove the cover from the chassis.
3. Remove the air baffle.
4. Unplug the fan cable from the server board (D).
5. At the left end of the module, press on tab (B) to release it from the chassis slot (C).
6. Lift the module from the chassis. When the right end is free, detach the USB cable.
7. Attach the USB cable to the replacement module.
8. Slide the “L” shaped foot on the right end of the module under the chassis tab near the chassis sidewall.
9. Lower the module to the chassis floor. Ensure it is situated between the raised guides, not on top of them.
10. Press down on the left end of the module until tab (B) fits into the chassis slot (C).
11. Plug the power cable into the system fan connector on the server board.
12. Install the air baffle.
13. Replace the chassis cover.

Caution : Before touching or replacing any component inside the LX50 server, disconnect all
external cables and follow the instructions in “Safety: Before You Remove the Cover” on
page 5-2 and “Removing and Replacing the Cover” on page 5-3. Always place the server on a
grounded ESD pad and wear a properly grounded antistatic wrist strap.
!
Caution : Failure to properly route the USB cable can cause it to interfere with the top cover. If
the cable is removed and then not placed properly under the cable clamp at the front, it may
result in the cover crushing the USB cable and destroying the intrusion sensor on the front
panel board.
✍
Note : Check to ensure that all cables are firmly seated and properly routed. Pay special care to
the flexible cable between the Main Board and backplane.
✍
Note : The Comprehensive Test should be run after changing any FRU, CRU, or adding an
optional component. See “Run System Diagnostic Test” on page 4-15.
