Chapter 10 Installing or Replacing Components
Replacing a Supervisor Module
If one of the supervisor modules has more memory than the other supervisor module, you must either
remove 4 GB from the module with 8 GB (see the
“Removing 4 GB of Memory from a Supervisor
Module” section on page 10-33
) or add 4 GB to the module with 4 GB (see the
“Adding 4 GB of Memory
to a Supervisor Module” section on page 10-30
).
Replacing a Supervisor Module in a Single-Supervisor System
If you need to replace the supervisor in a single-supervisor Cisco Nexus 7000 Series system, you must
shut down the system before replacing the supervisor.
Note
A replacement supervisor module comes with one DIMM (4 GB of memory) or, if your switch is running
Cisco NX-OS 5.1 (or later release), two DIMMs (8 GB of memory). If the switch not running a version
of Cisco NX-OS that is compatible with using 8 GB of memory, you must use only one DIMM (do not
install an additional DIMM).
Warning
Hazardous voltage or energy is present on the backplane when the system is operating. Use caution
when servicing.
Statement 1034
Caution
Handle the supervisor module carefully using an ESD wrist strap, holding the module only on its carrier
edges without touching any electronic circuitry, and placing the module on antistatic mats or antistatic
foam when it is not installed in the Cisco Nexus 7000 Series chassis.
To replace a supervisor module in a single-supervisor system, follow these steps:
Step 1
Place an antistatic mat or antistatic foam where you can place the new and old supervisor modules.
Step 2
If the replacement supervisor is in a shipping box, prepare the module for installation by following these
steps:
a.
Open the shipping box for the module and remove the module from its antistatic wrapping.
b.
If the plastic protector shown in
Figure 10-7
is included with the module, remove it by pulling it past
the back of the module. Keep the plastic protector and the other packing materials so that you can
easily ship the module at a later time.
