Installing Or Replacing A Line-Card Expansion Module (Lem) - Cisco Nexus 3400-S Hardware Installation Manual

Installing or Replacing a Line-Card Expansion Module (LEM)

• For an HVAC power source, plug the other end of the power cable into the power source.
• For a HVDC power source, verify that the circuit breaker is turned off and then connect each of the three cable
connectors to the appropriate DC and grounding terminals on the power source. If there is a cover plate for the
DC terminals, install the plate to prevent accidental contact with the terminals.
e) If using an HVDC power source, turn on the circuit breaker for the power source.
f) Verify that the power supply is operational by making sure that the power supply LED is green.
Installing or Replacing a Line-Card Expansion Module (LEM)
The switch can operate with one or more Line-card Expansion Modules (LEMs) that are installed in the
chassis. If there is at least one LEM that is installed and operating in the chassis, you can replace another LEM
or install a new LEM in an empty 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.
Warning Statement 1034—Backplane Voltage
Hazardous voltage or energy is present on the backplane when the system is operating. Use caution when
servicing.
Warning
Statement 1051—Laser Radiation
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
• Wear an electrostatic discharge (ESD) wrist strap or other ESD protective device while handling modules.
• Prepare an antistatic surface or packing materials for each module that you remove from the chassis.
Step 1 Open the packaging for the new LEM and inspect the module for damage.
If the module is damaged, contact the Technical Assistance Center (TAC).
