2.5" disk drives

This section describes how to remove and replace 2.5" disk drives.
The drive slot/locations are marked on the chassis 0-1, but the DD OS software still references the slots as 13-14. It is important
to identify the proper drive between the location called out in the FRU, and the location as specified in the software.

2.5" Disk Drive Overview

The rear of the enclosure supports up to two 2.5" SAS SSD drive carriers that slide into 2.5"drive bays.
The rear of the enclosure supports up to two 2.5" SAS SSD drive carriers that slide into 2.5" drive bays. For AIO configurations,
these drive slots must use 1 SSD and the expanded configuration must use 2 SSDs. For DLH configurations, these slots are
never populated with drives. The SAS SSD carrier has a lever mechanism that aligns and secures the drive in place. The lever
is secured by a slide latch. When the slide latch is slid down, the latch handle pop up and is lifted up to release the SAS SSD
carrier. To secure the latch handle, push it down and move the slide latch up to capture the handle.
For all configurations that do not populate all the rear 2.5" drive slots with 2.5" drive carriers, 2.5" drive fillers must be installed.
The plastic 2.5" drive filler slides into the 2.5" drive bays. The filler is simply pushed into the drive slot where it snaps into place.
Depressing the top filler latch and providing a firm pull of the filler removes it from the slot.
