PFR 500 RAID Storage Chassis circuit board modules
A PFR 500 includes one or two RAID Controller modules. Two RAID Controller
modules are installed when the redundant Fibre Channel option is installed. This
provides redundant Fiber Channel interface ports to the Profile system or Fibre
Channel switch fabric. The following figure shows a PFR500 Fibre Channel RAID
Storage Chassis with the two RAID Controller Modules installed. The RAID
Controllers are clearly labeled “A” or “B” on the rear panel of the canister. The “A”
and “B” RAID Controllers must be installed in the chassis as shown, they cannot be
swapped.
When the redundant Fiber Channel option is not installed, only one RAID Controller
is installed along with one LBB module as shown in the following figure. The LBB
module and the LBB contained in the RAID Controller module provide the two LBBs
required in the PFR500 Fibre Channel RAID Storage Chassis. The LBB and RAID
Controller modules are clearly labeled on the rear panel of each canister.
