EMC Disk-Array Processor Enclosure (DPE) Deskside Model FC4400/4500 Hardware Reference
Installing a Deskside DPE
reserved for the DPE, valid EA ranges for the DAE are 1 through
11 (decimal). We recommend that you assign address number 1 to
the DAE closest to the DPE.
Set the EA with the EA switch, which has one push button for
incrementing the address and another for decrementing it. To set
the EA, you must open the DAE’s front door. The switches have
lights that display the EA address. These lights are visible when
the door is closed.
Set the DAE enclosure address (EA) to the desired value using the
tip of a pen or paper clip, as shown below.
