Installing or Replacing a System Controller Module

Installing or Replacing a System Controller Module

The switch can operate with one or two system controller modules installed in the chassis. You can replace
one system controller module while there is another one installed in the chassis.
Statement 1029—Blank Faceplates and Cover Panels
Warning
Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous
voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt
other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system
unless all cards, faceplates, front covers, and rear covers are in place.
Warning
Statement 1034—Backplane Voltage
Hazardous voltage or energy is present on the backplane when the system is operating. Use caution when
servicing.
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 each side of the module) 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 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).
