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.
