Connecting the redundant EXP100, EXP700, or EXP710 drive
loop to the DS4300
After you configure the redundant drive loop using the EXP100, EXP700, or
EXP710 storage expansion enclosures, use the following procedure to connect a
redundant drive loop to the DS4300 Storage Subsystem. You will need two
fiber-optic cables to connect the redundant drive loop pair to the DS4300 Storage
Subsystem.
1. Connect drive loop A to the DS4300 Storage Subsystem, as shown in Figure 48
on page 65.
Starting with the last storage expansion enclosure in loop A, connect the In port
on the left ESM board to the expansion port located in the DS4300 controller A
module/CRU DS4300 Storage Subsystem.
Leave the Out port on the left ESM board on the first storage expansion
enclosure and the In (lower) connector on drive mini hub 4 unoccupied.
