Chapter 10 Installing or Replacing Components
Replacing a Supervisor Module
Step 20
Reconnect the CMP cable to the CMP MGMT ETH port as explained in the
“Connecting the Supervisor
CMP Port” section on page 7-5
.
Step 21
If you need to upgrade the other supervisor module to 8 GB (both modules must have the same amount
of memory), repeat Steps 2 through 19.
Step 22
Verify that the upgraded module has 8 GB of memory. If there are two supervisor modules installed in
the switch, use the
system switchover
command to make that module active, and then use the
show
system resources
command. If there is just one supervisor module installed in the switch, use the
show
system resources
command.
Step 23
If you need to upgrade another supervisor module to 8 GB (both supervisor modules in a switch with
two supervisors must have the same amount of memory), repeat Steps 2 through 22.
Removing 4 GB of Memory from a Supervisor Module
If you need to remove 4 GB of memory from the supervisor modules so that they each have only 4 GB
of memory, you must remove the DIMM from the second memory slot from the front of each installed
supervisor module.
Note
If the switch has two supervisor modules, both must have the same amount of memory. If you downgrade
one supervisor module to 4 GB of memory, you must also downgrade the other supervisor module to 4
GB of memory.
To remove 4 GB of memory from a supervisor module, follow these steps:
Step 1
Follow ESD procedures, which include wearing an ESD wrist strap and placing antistatic foam or
antistatic padding where you will place the supervisor module while working with it.
Step 2
Disconnect the cables attached to the front of the module to be removed. If there are two supervisor
modules installed in the switch, disconnect the cables from the standby supervisor.
Note
If the chassis has two supervisor modules and you disconnect the active supervisor module, that
supervisor goes into standby mode and the other supervisor becomes the active supervisor.
Step 3
Loosen and fully unscrew both captive screws on the installed supervisor module that you need to
upgrade.
Step 4
Press both ejector release buttons on the ends of the module (see Callout 2 in
Figure 10-5 on page 10-18
)
to push out the ejector levers and to disconnect the module.
Note
If you stop this procedure at this point without removing the module and need to power it up,
simultaneously press both ejector levers back to the face of the module until they click, secure both of
the module captive screws to the chassis, and then use the
no poweroff module
slot_number
command
to power up the module.
Step 5
Simultaneously rotate the two ejector levers outward to unseat the module from the midplane connector
(see Callout 3 in
Figure 10-5 on page 10-18
).
Step 6
With a hand on each ejector lever, pull the module part way out of its slot in the chassis.
