Replacing a Supervisor Module
FSB Clk - 532 Mhz : Freq - 2144 Mhz - 2128 Mh
MicroCode Version : 0xffff0002
Memory - 32768 MB : Frequency - 1067 MHZ
Step 3 Monitor the console output for the active Supervisor 2. When the standby Supervisor 2E fully boots up,
note that the console displays a SYSLOG message similar to the following:
2012 Jul 26 14:28:23 switch %SYSMGR-2-CTIVE_LOWER_MEM_THAN_STANDBY: Active Supervisor in
slot 1 is running with less memory than standby supervisor in slot 2.
This message states that the Supervisor 2E module has more memory than the Supervisor 2 module (as
expected).
Step 4 Verify that both supervisor modules have synchronized their states by using the show mod and show
system redundancy ha status commands.
switch# show mod
Mod Ports Module-Type Model Status
--- ----- ----------------------- -------------- ---------
1 0 Supervisor module-2 N7K-SUP2 active
2 0 Supervisor module-2 N7K-SUP2E ha-standby
switch# show system redundancy ha status
VDC No This supervisor Other supervisor
------ --------------- ----------------
vdc 1 Active with HA standby HA standby
vdc 2 Active with HA standby HA standby
vdc 3 Active with HA standby HA standby
vdc 4 Active with HA standby HA standby
Step 5 Make the Supervisor 2E module active by using the system switchover command.
switch# system switchover
When the Supervisor 2E becomes active, the Supervisor 2 powers down and will not come up as a
standby supervisor.
2012 Jul 26 14:50:19 switch %$ VDC-1 %$ %SYSMGR-2-SUP_POWERDOWN; Supervisor in slot 1 is
running with less memory than active supervisor in slot 2
2012 Jul 26 14:50:19 switch %$ VDC-1 %$ %SYSMGR-2-CONVERT_STARTUP_ABORTED: Conversion of
startup-config failed.
2012 Jul 26 14:50:19 switch %$ VDC-1 %$ %PLATFORM-2-MOD_PWRDN: Module 1 powered down
Step 6 Verify that the Supervisor 2E module is active and that the Supervisor 2 is powered down by using the
show module command.
switch# show mod
Mod Ports Module-Type Model Status
--- ----- ----------------------- -------------- ---------
1 0 Supervisor module-2 N7K-SUP2 powered-dn
2 0 Supervisor module-2 N7K-SUP2E active *
...
Mod Power-Status Reason
--- ------------ ----------------------------
1 powered-dn Policy trigger initiated reset: Stdby has lower mem than active
Step 7 Remove the Supervisor 2 module, which is powered down (LEDs are off).
Step 8 Install a Supervisor 2E module in the open slot and connect it to the console (see the “Replacing a
Redundant Supervisor Module During System Operations” section on page 10-16).
Step 9 Verify that both supervisor modules have synchronized their states by using the show mod and show
system redundancy ha status commands.
