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 10-33.
