Installing a DAE2
4. Attach the copper cable from the external device (storage
processor or another DAE2) to the PRI connector as shown in
Figure 2-4. If you are continuing the loop to another DAE2, attach
a cable from the EXP connector to the PRI connector in the next
DAE2.

5. If you are installing multiple disk enclosures, cable them as
shown in Figure 2-5 or Figure 2-6.
The example configuration in Figure 2-5 shows a CLARiiON
®
CX600 storage processor enclosure (SPE) below four DAE2
disk-array enclosures. The five devices support two completely
redundant loops. Note that the external device connects to the
Primary disk enclosure connectors, and subsequent enclosures
connect in an Expansion-to-Primary chain.
EA 0, loop 0 must be a Fibre Channel DPE2 or DAE2. ATA enclosures do not
support the boot and SPS requirements of the first disk array in a storage
system.
