To replace an ISIS 5500 | 5000 enclosure:
1. Power-off the old Engine by clicking Start > Shut Down.
2. Disconnect the two power cords from the back of the old Engine.
3. Disconnect the 1-Gb connections and any 10-Gb (optical) connections from old Engine.
4. Carefully remove both system drives from the rear of the old Engine. Put them in a safe
place.
These are mirrored drives. The order in which you replace these drives in the new Engine
should not matter. Although it would be good practice to mark the system drives as the upper
and lower and replace them back in the same order in the new Engine.
5. Carefully remove all (16) data drives from the front of the old Engine and put them in a safe
place.
These data drives are labeled by the system as three RAID groups (5 drives per group) and
one spare drive. The order in which you replace these drives in the new Engine should not
matter. Although it would be good practice to mark the data drives as to the slot location and
replace them back in the same order in the new Engine.
6. Remove the old Engine from the rack.
7. Install the new Engine into the rack (without the system or data drives).
8. Carefully reinsert the both system drives into the rear of the new Engine.
If you recorded the locations from which the drives were removed on the original Engine,
insert them into the same upper and lower locations.
9. Carefully reinsert all data drives into the original position in which they were in on the old
Engine.
