TLA715 Dual Monitor Portable Mainframe Service Manual
Individual Fans
You will need a screwdriver with a size T-15 Torx tip, a Philips screwdriver,
pliers, a side cutter, and a scribe or jeweler’s screwdriver or other small, pointed
tool to perform this procedure.
Use the following procedure to remove an individual fan from the rear chassis
fan tray:
1.
Do the Rear Chassis Fan Tray removal procedure, page 6--30.
2.
Remove the screw that secures the hold down brackets to the rear chassis fan
tray. (See Figure 6--17 on page 6--33.) If you are replacing one of the two
fans nearest the cable connector, you need remove only one of the hold-down
brackets. Otherwise, remove two.
3.
Lift the fan from the rear chassis fan tray. If necessary, use the pliers to
gently straighten the metal tabs holding the fan to the rear chassis fan tray
and then remove the fan.
4.
Note the fan cable dress and remove the tie holding the cables together near
the connector. Remove the cable tie(s) if necessary.
5.
Remove the fan wires from the cable connector. (Pay attention to the wire
color locations for reinstallation.) Use a scribe or jeweler’s screwdriver to
gently push down the “finger” of metal that secures (latches) the wire end
into the connector. (See insert, Figure 6--17 on page 6--33.) At the same time,
pull gently on the wire until it comes out of the connector.
