Front door
The front door has a locking latch and an EMI shield. The latch is a push button with
a removable locking key that you can use in any PFC 500 or PFC 500E. When the door
is open, you can remove or install disk modules.
IMPORTANT: The front door must be closed for the PFC500/E to be EMI
compliant. Opening the door to access the disk modules is a service procedure.
RAID Controllers (RCs)
The RC is the PFC 500 ’s intelligent component. It defines the PFC 500 and
differentiates the PFC 500 from a PFC500E . An RC is a printed-circuit board
with one dual in-line memory module (DIMM), a bezel with status lights, and
securing latches.
The RC has three Fibre Channel ports. Port A and Port B are for connecting to a
Profile XP Media Platform. The expansion connector (EXP) is for connecting to a
PFC500E. The port interface is called the RC front end. It can connect to a Profile XP
Media Platform’s Fibre Channel storage board. You set an RC’s FC-AL address ID
using rotary switches.
The RC connects to disk modules in the same chassis via an internal FC-AL. The
expansion port extends the internal FC-AL to the corresponding link control card
(LCC) in the PFC 500E chassis. This FC-AL is referred to as the RC back end.
An RC also has an RJ-type connector for serial communications with a console.
Each RC has two status lights visible from the rear of the PFC 500/E. For the meaning
of these lights, see “Monitoring PFC500/E status” on page 42.
