EMC Disk-Array Processor Enclosure (DPE) Deskside Model FC4400/4500 Hardware Reference
Servicing and Upgrading a Deskside DPE
Installing an SP or SP Filler Module
CAUTION
!
Handle an SP gently and use an ESD wristband.
1. Perform this step only if you are installing the DPE into an FC-AL
environment. Otherwise, continue to the next step.
To communicate in an FC-AL environment, each SP requires a
unique FC-AL address ID (the front-end address). The FC-AL
protocol translates the address ID into an 8-bit arbitrated loop
physical address (ALPA). Valid Fibre Channel address IDs range
from 0 through 125 (decimal) (0 through 7D hexidecimal).
Each SP’s Fibre Channel address ID must be unique on the Fibre Channel
loop. We suggest a unique address ID for each SP.
At the back of the deskside DPE, at each SP use the SP FC-AL ID
switches (see illustration below) to set the address ID (refer to the
table below).
Using the SP FC-AL ID switches, set the FC-AL address ID, as
shown next.
