adding a 5108 chassis

[russ.givens]

We purchased UCS (2 6120XP fabric interconnects and 2 5108 chassis with blades) a couple of years ago.  We are just getting to the point of needing to add an additional chassis.  I'm presuming adding the additional chassis is pretty straight forward.  Plug the chassis into the fabric interconnects, allocate the a couple of the ports on the fixed modules to be Server ports, and then power the chassis on.  Is there anything that I need to be aware of or could be a potential gotcha?

When adding a new chassis the firmware shipped with the IOMs may be different than what you're currently running.  The IOMs will automatically download the matching fw version from the FI's - so just be patient once enabling the server ports for the new chassis and blade to discover.  Could take up to 20mins (to pull upgrade image and reboot if necessary).

Other than that, ensure all IOM - FI links are acknowledged.  Once the chassis is discovered you can re-ack the new Chassis just to be sure.
