Resetting the Password
Resetting the Password 9
It may become necessary at some point to reset the CMM password to its default of cmmrootpass.
The CMM has one on board dip switch labeled S2-1 to perform this action. Refer to the Intel®
NetStructure™ MPCMM0001 Hardware Technical Product Specification for the location of the
switch. Setting the switch and powering up the CMM will cause the password to reset to its default.
The CMM then needs to be removed and the switch then needs to be turned off again.
9.1 Resetting the Password in a Dual CMM System
In redundant systems containing dual CMMs, one active, one standby, the password should be reset
on the standby CMM. Once reset to its default, the default password will synchronize itself to the
active CMM. This prevents the need to perform the reset on both CMMs and a failover.
1. Open the ejector latch on the standby CMM and wait for the blue hot swap LED to illuminate,
indicating the CMM is safe to remove from the system.
2. Remove the standby CMM from the chassis.
3. Set dip switch S2-1 to “on”. The dip switch has a label indicating which way is on.
4. Re-insert the CMM into the system and allow the CMM to fully boot (blue light will go off
when fully booted).
5. An OK health event will occur indicating that the passwords on both CMMs have been reset
and were synched from the standby CMM. A SEL entry will be recorded, and a trap will be
sent out.
6. Once at the login prompt, the password should now be reset to its default of cmmrootpass.
7. Login to the active CMM to ensure the password was reset.
8. Open the ejector latch on the standby CMM and wait for the blue hot swap LED to illuminate,
indicating the CMM is safe to remove from the system.
9. Remove the standby CMM from the chassis.
10. Set dip switch S2-1 back to original “off” position.
11. Re-insert the CMM into the system and allow the CMM to fully boot (blue light will go off
when fully booted).
12. Login to the CMM and operate as normal.
13. Use the passwd command on the active CMM to change the CLI password if desired. The new
password will sync to the standby.
