About the Rackmount Disk-Array Processor Enclosure
Figure 1-6 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
DPE or DAE. When the door is open, you can remove or install disk
modules.
Storage Processors
(SPs)
The SP is the DPEs intelligent component. It defines the DPE and
differentiates the DPE from a DAE. An SP is a printed-circuit board
with dual in-line memory modules (DIMMs), a bezel with status
lights, and securing latches. The following figure locates the SP ports,
the status lights, the location of the DIMMs, and the FC-AL ID rotary
switches.
Locking latch
with key
The front door must be closed for the
DPE to be EMI compliant. Opening
the door to access the disk modules is
a service procedure.
