Installing or Replacing a Line Card
Installing or Replacing a Line Card
The switch can operate with one or more line cards installed in the chassis. If there is at least one line card
installed and operating in the chassis, you can replace another line card or install a new line card in an empty
line card slot.
Warning
Statement 1029—Blank Faceplates and Cover Panels
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.
Statement 1034—Backplane Voltage
Warning
Hazardous voltage or energy is present on the backplane when the system is operating. Use caution when
servicing.
Statement 1051—Laser Radiation
Warning
Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams
or view directly with optical instruments.
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 line card and inspect the module for damage.
If the module is damaged, contact 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
two captive screws 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) Disconnect and label each of the interface cables from the module.
b) Push and hold the release button on both ejector levers and then rotate both levers 45 degrees from the module as
shown in the following figure.
