Install Disk Drives in a 5U84 Enclosure
Prerequisites
The ClusterStor L300 and L300N rack has been unpacked, and moved at least off the pallet and down the ramps
to the floor. It may already be located in its final operating position.
About this task
How to install disks in a ClusterStor L300 and L300N 5U84 enclosure (SSU).
IMPORTANT: Disk drives are labeled and they must be installed in the exact order and in the exact slots
where they were installed at the factory.
Typically, 5U84 enclosures are shipped empty and must be populated at installation, particularly the lower two
enclosures in a rack, which must be populated before safely moving the rack from the bottom of the ramps to its
final destination.
There are two methods of loading disks: using the speedloader device, which loads seven disks at once to speed
disk population, and the manual method, which loads one disk at a time. Both methods are described in this
procedure.
CAUTION:
EQUIPMENT OVERHEATING
All drive slots must have a disk drive carrier module or a dummy carrier module installed to maintain a
balanced airflow.
CAUTION:
EQUIPMENT DAMAGE OR PERSONAL INJURY
To ensure rack stability, open only one drawer in a 5U84 (SSU) enclosure at a time. Do not open
multiple drawers at the same time.
CAUTION:
EQUIPMENT DAMAGE
Observe ESD precautions when handling this equipment. Failure to do so can result in equipment
damage.
Procedure
1. Refer to the packaging documentation to locate the marked carton containing the drives for the target 5U84
enclosure.
