System Board Cooling Fans

There are three system board cooling fans located behind the left side of the workstation's
front panel. This section describes how to remove and replace them.
NOTE
If the LCD displays an error message that relates to a turbocooler fan on a
microprocessor mounted on the system board, you will need to replace the
entire system board tray assembly. Follow the removal and replacement
procedures in "System Board Tray Assembly" on page 110.
Removing a System Board Cooling Fan
To remove a system board cooling fan, do the following:
1. Remove the top panel and the left side panel of the workstation.
2. If you are removing a system board cooling fan from a J7xxx workstation, you must also
remove the front and rear air dividers and the two DC/DC converter units that are
attached to the J7xxx's system board. To do this, follow the removal procedures in
"DC/DC Converter Units and Air Dividers (J7xxx Only)" on page 108.
3. Disconnect the appropriate fan cable from the system board. Figure 4-29 shows the
locations of the three system board cooling fans and their respective cables. Figure 4-30
on the next page shows the removal of a fan cable from its connector on the system
board.
