14.8.3.5 Cisco SFS 7000 Series InfiniBand Server Switches
The instructions for changing the administrative passwords for Cisco® SFS 7000 Series InfiniBand
Server Switches are located in the documentation for the specific switch model. Some of this
documentation is available at the following web address:
http://docs.hp.com/en/highperfcomp.html
Additionally, you can access the full complement of Cisco documentation for the SFS 7000 Series
InfiniBand Server switches at the following web address:

The following table lists default accounts for three Cisco SFS 7000 Series InfiniBand Server
switches.

14.8.4 Changing the Console Port Password
When you change the password for an iLO, MP, or IPMI, you must ensure that the console port
password matches its counterpart in the CMDB.
CAUTION: Changing the console port password can cause complications if you do not also
update the CMDB manually with the new password. Updating the CMDB is beyond the scope
of this document.
If you make an error updating the CMDB, you can corrupt the database and jeopardize system
operation; for example, some commands might cease to function.
If you must update the CMDB, be sure that you back it up as described in “Backing Up the
Configuration Database” (page 81) before changing the console port password.
The HP XC Hardware Preparation Guide describes changing the console port password for an iLO,
MP, or IPMI.
14.8.5 Synchronizing the BMC/IPMI Password for CP6000 Systems
The CP6000 systems require an additional step to synchronize the IPMI password with the
console port. The BMC/IPMI password must match the console port password on all nodes.
You can connect the head node console port either internally or externally to the HP XC system.
Follow the procedures appropriate for your installation.
