Chapter 9 Replacement Procedures
Replacing a Supervisor Module

Adding 4 GB of Memory to a Supervisor Module
If you need to add 4 GB of memory to the supervisor modules on your switch so that they have 8 GB of
memory, the switch must be running NX-OS Release 5.1(1) or later release.
Note
If the switch has two supervisor modules, both must have the same amount of memory. If you upgrade
the standby supervisor module to 8 GB of memory, you must then switch the active supervisor to standby
and upgrade the new standby supervisor to 8 GB of memory.
Note
If you are using an earlier version of Cisco NX-OS, the supervisor modules can have only 4 GB of
memory. If you need to remove 4 GB of memory to have only 4 GB of memory in a supervisor, see the
“Removing 4 GB of Memory from a Supervisor Module” section on page 9-23
.
To add 4 GB of memory to the supervisor modules, 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 supervisors 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 module.
Step 4
Press both ejector release buttons on the ends of the module (see Callout 2 in
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
Step 6
With a hand on each ejector lever, pull the module part way out of its slot in the chassis.
Step 7
Grasp the front edge of the module with one hand and place your other hand under the lower side of the
module to support its weight. Pull the module out of its slot.
