Fan Tray Assembly Removal And Replacement - 3Com 3C94024 - CoreBuilder 9400 1000SX Switch Getting Started Manual

Fan Tray Assembly Removal and Replacement

The CoreBuilder 9400 is cooled by the fan tray
assembly, which contains two 12-volt DC fans. The
fans are thermally controlled, which means that they
run at slower speeds when the system is operating at
temperatures of less than 30
when the system temperature is above that.
You need no tools to remove the fan tray. You can
remove and replace the fan tray with the power on.
To remove and replace the fan tray assembly, follow
these steps:
Facing the front of the system, squeeze the fan tray
1
latching tab.
Slide the fan tray out of the system.
2
Slide the new fan tray into the system chassis.
3
To seat the fan tray, ensure that the connectors are
4
aligned, and then push the fan tray inward until the
connectors engage and the fan tray latches. You feel
a slight resistance as the connectors engage.
CAUTION: If the resistance is too great, the
connectors may not be aligned. Forcing the fan tray
inward could damage the connectors. If necessary,
remove and reinsert the fan tray, ensuring that the
connectors are properly aligned.
