Each Expansion storage shelf contains two I/O modules. The modules are labeled
A and B, from left to right as you look at the rear panel of a shelf. Each module has
three SAS-3 ports that are labeled A, B, and C from left to right.
A yellow label states that port B is for attachment to a server only. You cannot use
this port without permission and assistance from Veritas Technical Support.
The SAS-3 ports connect to the SAS port on each RAID controller on the Primary
shelf and to other Expansion shelves.
