5U84 enclosure chassis
The 5U84 enclosure includes the following features:
5U84 chassis configured with up to 84 LFF disks in DDICs. See 5U84 enclosure system - plan view of drawer accessed from
front panel on page 16.
5U84 chassis configured with SFF disks in 2.5" to 3.5" hybrid driver carrier adapter.
5U84 empty chassis with midplane, module runner system, and drawers.
The chassis has a 19-inch rack mounting that enables it to be installed onto standard 19-inch racks and uses five EIA units of
rack space (8.75").
At the front of the enclosure, two drawers can be opened and closed. Each drawer provides access to 42 slots for Disk
Drive in Carrier (DDIC) modules. DDICs are top mounted into the drawers as shown in 5U84 enclosure system - plan view
of drawer accessed from front panel on page 16. The front of the enclosure also provides enclosure status LEDs and drawer
status/activity LEDs.
The rear of the enclosure provides access to rear panel CRUs:
Two controller modules or IOMs
Two PSUs
Five FCMs
5U84 enclosure drawers
Each enclosure drawer contains 42 slots, each of which can accept a single DDIC containing a 3.5" LFF disk drive or a 2.5" SFF
disk drive with an adapter.
Opening a drawer does not interrupt the functioning of the storage system, and DDICs can be hot-swapped while the enclosure
is in operation. However, drawers must not be left open for longer than two minutes, or airflow and cooling will be compromised.
NOTE: During normal operation, drawers should be closed to ensure proper airflow and cooling within the enclosure.
A drawer is designed to support its own weight, plus the weight of installed DDICs, when fully opened.
CAUTION: The sideplanes on the enclosure drawers are not hot swappable or customer serviceable.
Safety features
To prevent the rack from tipping, slide only one enclosure out of the rack at a time.
The drawer locks into place when fully opened and extended. To reduce finger pinching hazards, two latches must be
released before the drawer can be pushed back into the drawer slot within the enclosure.
Each drawer can be locked shut by turning both anti-tamper locks clockwise using a screwdriver with a Torx T20 bit (included
in your shipment). The anti-tamper locks are symmetrically placed on the left and right sides of the drawer bezel. Drawer status
and activity LEDs can be monitored by two drawer LEDs panels located next to the two drawer-pull pockets located on the left
and right side of each drawer.
