Chapter 10 Installing or Replacing Components
Replacing a Supervisor Module
Note
While the configuration is applied on the Supervisor 2 or Supervisor 2E module you will see an error
that indicates a problem with the cmp-mgmt interface or AUX port. The Supervisor 2 and Supervisor 2E
modules do not have the CMP utility nor the AUX port, so you can disregard this error message.
switch(config)#
interface cmp-mgmt module 5
^
Invalid interface format at ‘^’ marker.
...
switch(config)# line com1
^
% Invalid command at ‘^’ marker.
Note
If the imported configuration file includes configurations for Fabric Extenders (FEXs) and those
modules are not up yet, you will see error messages for that. If that happens, we recommend that you
run the FEX configuration again after the FEX modules come online. You can verify the status of the
FEX modules and for the associated server-facing interfaces by using the
show fex
and
show interface
brief
commands.
Note
If you have not inserted the standby supervisor module until now, do not insert it during this step.
Instead, wait until you complete this procedure before installing the standby supervisor module.
Step 21
Save the configuration in the startup configuration by using the
copy running-config startup-config
vdc-all
command.
switch(config)#
copy running-config startup-config vdc-all
Replacing Supervisor 2 Modules with Supervisor 2E Modules
Before migrating from Supervisor 2 modules to Supervisor 2E modules, note the following guidelines:
•
This migration process is not disruptive for switches with redundant (two) supervisors but it is
disruptive for switches that have only one supervisor module.
•
Non disruptive backward migration (migrating from Supervisor 2E modules to Supervisor 2
modules during switch operations) is not supported—in a switch with two supervisor modules and
an active Supervisor 2E module, a Supervisor 2 will not boot up nor synchronize with the active
Supervisor 2E module.
To migrate from using Supervisor 1 modules to Supervisor 2 or Supervisor 2E modules, follow these
steps:
Step 1
Replace one of the Supervisor 2 modules by following the steps in the
“Replacing a Redundant
Supervisor Module During System Operations” section on page 10-16
.
Step 2
Verify that the Supervisor 2E module has 2 CPUs and 32 GB of DRAM by looking at the bootup output
(see the highlighted portions in the following example).
CPU - 2 : Cores - 4
: HTEn - 1 : HT - 2 : Features - 0xbfebfbff
