Locating an SM or NIM
See the “Locating Internal and External Slots for Modules” section on page 6-5 to locate the SM or NIM
slot on the motherboard.
Removing an SM or NIM
Use the following procedure to remove an SM:
Step 1 Read the “Safety Warnings” section on page 6-2 and disconnect the power supply before you perform
any module replacement.
Step 2 Access the SM slot. See Figure 6-2 for the various NIM and SM slot locations.
Step 3 Loosen the captive screws to open the slot cover. See Figure 6-8 and Figure 6-9.
Step 4 Pull the SM out of the connector on the motherboard. Keep the SM parallel with the motherboard to
prevent damage to the slot and standoff.
Step 5 Place the SM in an antistatic bag to protect it from ESD damage.
Installing an SM
To install an SM, use a number 2 Phillips screwdriver or flat-blade screw drive, and a 1/4-inch nut driver
or wrench.
Step 1 Read the “Safety Warnings” section on page 6-2 and disconnect the power supply before you perform
any module replacement.
Step 2 Identify the SM slot you will insert the SM into.
Step 3 Loosen the captive screws to open the slot cover. See Figure 6-8 and Figure 6-9.
Step 4 Insert the SM to the system board.
Note Be sure to press firmly on the SM until the board seats onto the connector.
Step 5 Insert the screws from the accessory kit through the SM into the standoffs. See Figure 6-20. Carefully
tighten the screws with a Phillips screwdriver (torque 6 to 8 in-lb or 0.7 to 1.1 Nm.).
