Connecting to the EVA6400 or EVA8400 online
NOTE: You can only add one disk enclosure online at a time.
1. Using a power cord provided in your kit, plug one end into the disk enclosure power supply and
the other end into a rack power distribution module. You will briefly hear a rush of air as power
is applied, and the LEDs on the power UID flash. The power UID standby switch LED remains
amber.
2. With the remaining power cord, connect the other power supply to a rack power distribution
module. The power UID power switch LED turns green. The I/O module index number will likely
display 00, but if not, ignore the index number at this time.
3. Follow the cabling procedure and diagram in either
9) or "Connecting to an EVA8400 offline " (page 11)
and between the disk enclosures. In the offline procedure, connections to the ports of I/O module
A are completed first, then the connections to the ports of I/O module B are completed. Either
I/O module can be cabled first as long as the other I/O module ports are not unplugged until
cabling is complete on the first I/O module and you have completed step 4. This enables the
controllers to redundantly manage storage while the cables are briefly pulled and reconnected
on one side.
