Installing and Removing Modules
Installing and replacing PCMCIA cards
8
Using a number 2 Phillips screwdriver, secure the module into the unit by
tightening the thumbscrews on the LPM.
9
Reconnect the cables, as described in “Connecting to the LPMs” on page 2-3.
Installing and replacing PCMCIA cards
To remove the PCMCIA cards from the control module, push the square, flat black
buttons at the bottom of each PCMCIA card to eject the cards. After the cards are
removed, make sure they remain guarded against static discharge.
To install the PCMCIA cards in the control module, line the card edge up with the
guides, and push the card in until the black ejector button pops back up.
Replacing the cooling module
The cooling module contains fans for cooling the unit and the electronics that control
and monitor their operation. The cooling module is installed in the rear of the
chassis. It is not necessary to remove power from the unit while replacing the cooling
module.
!
Caution
To avoid overheating the unit, you must minimize the time that the cooling
module is removed from the chassis. Have the new module unpacked and ready for
installation before removing the old cooling module.
To replace an LPM:
1
Put on the antistatic wrist strap, as recommended in “Preventing static discharge
damage” on page 1-4, and plug it into an ESD grounding jack located on the
front or back of the unit. (See Figure 1-5 on page 1-7 and Figure 1-7 on
page 1-10.)
2
Using a number 2 Phillips screwdriver, fully loosen the cooling module locking
screw, shown in Figure 6-4.
Warning
Keep your fingers away from the fan blades in the cooling module. Fan
blades may be moving with the cooling module is removed from the enclosure.
3
Grasp the extraction handle of the cooling module and pull the cooling module
about 0.5in. (12.7mm) out of the enclosure. Wait until the fans stop moving (at
least 20 to 30 seconds).
4
When the fan blades have stopped moving pull the cooling module straight out
of the chassis, as shown in Figure 6-4.
