Chapter 9 Replacement Procedures

Replacing a Supervisor Module

Step 16

Screw in the two captive screws to the chassis and tighten them to 8 in-lb (0.9 N·m).

Step 17

Reconnect the console cable to the CONSOLE SERIAL PORT as explained in the

“Connecting to the

Console” section on page 6-2

Step 18

If the previous supervisor module was connected to an asynchronous device through a modem, connect
the modem cable to the COM1/AUX SERIAL PORT as explained in the

“Connecting to the Console”

section on page 6-2

Step 19

Reconnect the network management cable to the MGMT ETH port as explained in the

“Setting Up the

Management Interface” section on page 6-4

Step 20

Reconnect the CMP cable to the CMP MGMT ETH port as explained in the

“Connecting the Supervisor

CMP Port” section on page 6-5

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 9-5 on page 9-15

)

to push out the ejector levers and to disconnect the module.
