Robert,
do you want to say UCS 5108?
If yes then thats a UCS chassis comprising of 8 slots.
and you can manage the whole setup using UCS manager.
UCS manager is set up while configuring FIs.
you need to give management IPs to each FI plus a virtual IP.
UCS configuration guide for reference purpose:
