2C2D configuration. The disk enclosure is added to loop 1 above disk enclosure 2 (S-2). The dashed
lines indicate the changes to the cabling when compared to
procedure is written so it can be adapted; specific references to
aid comprehension.
1. Power down the array and existing disk enclosures.
2. Unplug DP1-A on controller A from P1 (I/O-A) on the disk enclosure in loop 1 (S-2) and connect
it to P1 (I/O-A) on the newly added disk enclosure (S-3 in
3. Unplug DP1-B on controller B from P1 (I/O-B) on the disk enclosure in loop 1 (S-2) and connect
it to P1 (I/O-B) on the newly added disk enclosure (S-3 in
4. Connect P2 (I/O-A) on the newly added disk enclosure in loop 1 (S-3) to P1 (I/O-A) on the disk
enclosure directly below it (S-2).
5. Connect P2 (I/O-B) on the newly added disk enclosure in loop 1 (S-3) to P1 (I/O-B) on the disk
enclosure directly below it (S-2).
6. Using a power cord provided in your kit, plug one end into a disk enclosure power supply and
the other end into a rack power distribution module. Plug the left power supply into the left module
and the right power supply into the right module.
7. Press and hold the power push-button (located at the rear of the disk enclosure) long enough to
power up the disk enclosure.
8. Power on the other disk enclosures attached to the array and visually check that each enclosure
powers on without errors. Wait at least one minute after all the enclosures are powered on for
the drives to spin up and stabilize.
9. Power on controller A by pressing the power button on the rear of the controller until the controller
responds (it may take up to 10 seconds for the controller to power on). Repeat this step for
controller B. Wait five minutes for the array to stabilize.
10. Verify that I/O modules A and B on the added disk enclosure have been assigned an index
number of the next higher enclosure number. For example, if the previous highest index number
was "3," then the installed enclosure should display "4."
