Hardware Setup Guide
Step 1:
Locate the carton that contains the DDICs shipped with the product that need to be installed in each of the
5U drawers in the enclosure. Each drive is labeled with a number that corresponds to the drawer slot that it
needs to be installed in.
Step 2:
Ensure that you adhere to the following guidelines to install the DDICs in the drawers:
n
The minimum number of disks that are supported by the enclosure is 28, 14 in each drawer.
n
DDICs must be added to disk slots in complete rows (14 disks at a time).
Step 3:
The drives are numbered beginning at the front of each drawer, install each DDIC consecutively by number,
and alternately between the top drawer and the bottom drawer. For example, first install the DDICs 0-13 in
slots 0–13 in the top drawer, and then DDICs 42–55 in slots 42-55 in the bottom drawer. After that, install slots
14–27, and so on.
n
The number of populated rows must not differ by more than one row between the top and bottom drawers.
n
Hard disk drives (HDD) and solid-state drives (SDD) can be mixed in the same drawer.
n
HDDs installed in the same row should have the same rotational speed.
n
DDICs holding 3.5" disks can be intermixed with DDICs holding 2.5" disks in the enclosure. However, each
row should be populated with disks of the same form factor (all 3.5" disks or 2.5" disks).

CAUTION
n
Observe the hot surface label that is affixed
to the drawerOperating temperatures inside
enclosure drawers can reach 60°C (140°F) .
Take care when opening drawers and
removing DDICs.
n
To prevent a rack from tipping over, drawer
interlocks stop users from opening both
drawers simultaneously. Do not attempt to
force open a drawer when the other drawer
in the enclosure is already open. In a rack
containing more than one U84 enclosure,
do not open more than one drawer per rack
at a time.
