Extracting the Circuit Card
To extract the circuit card, do the following:
1. Locate the circuit card to be replaced within the card cage.
2. Disconnect any attached cables.
NOTE:
Pay close attention to the connectivity of each cable to make it easier
to connect them to the replacement circuit card.
3. If there are cables attached to other circuit cards which would impede the
removal of the circuit card, disconnect them and place them to the side.
NOTE:
Pay close attention to the connectivity of each cable.
4. Remove the retaining screw from the circuit card faceplate and save it.
5. Remove the circuit card from the backplane slot by gently pulling on each
corner of the circuit card.
NOTE:
Note the slot assignment because you must install the replacement
circuit card in the same backplane slot. See “Component
Assignments” in Appendix A, ‘‘System Configuration’’,” for circuit
card slot assignments.
6. Remove the circuit card from the MAP/5P.
!
CAUTION:
Hold the circuit card carefully by the edges and place it on a
grounded mat. See “Protecting against Damage from Electrostatic
Discharge” in Chapter 4, ‘‘Getting Inside the Computer’’,” for detailed
electrostatic discharge precautions.
7. If the circuit card being replaced is defective, note all symptoms of failure
and include this information with the circuit card when it is returned.
Installing a Circuit Card
!
CAUTION:
Observe proper electrostatic discharge precautions when you handle
computer components. Wear an antistatic wrist strap that touches your bare
skin and connect the strap cable to an earth ground. See “Protecting
against Damage from Electrostatic Discharge” in Chapter 4, ‘‘Getting Inside
the Computer’’.
