Installing or Replacing a System Controller Module
Before You Begin
• You must wear an electrostatic discharge (ESD) wrist strap or other ESD protective device while handling
• Prepare an antistatic surface or packing materials for each module that you remove from the chassis.
Step 1 Open the packaging for the new system controller module and inspect the module for damage.
If the module is damaged, alert the Technical Assistance Center (TAC).
Step 2 If you are installing the module in an empty slot, remove the blank module that is already in that slot by unscrewing its
captive screw and pulling it out of the slot. Go to Step 4.
Step 3 If you are replacing a module that is currently in the chassis, remove the existing module from the chassis by following
these steps:
a) Unscrew the two captive screws (one on the left side of the module and one on the right side) until the screws are no
longer in contact with the chassis.
b) Slide and hold the middle handle on the ejector lever toward the end of the lever.
c) Rotate the ejector lever away from the front of the module.
As you rotate the lever, the module unseats from the midplane and moves slightly forward.
d) Use the lever to pull the module a couple of inches (about 5 cm) out of the slot.
e) Use one hand to hold the front of the module, place your other hand under the module to support its weight, pull the
module out of the chassis, and set the it on an antistatic surface or inside an antistatic bag.
Step 4 To install the new module, follow these steps:
a) Slide and hold the middle handle on the ejector lever toward the end of the lever (see the following figure).

3 Rotate the ejector lever to the front of the module
so that its locking knob grabs the chassis frame and
seats the module on the midplane.
