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 2 minutes, or airflow and
cooling will be compromised.
IMPORTANT: During normal operation, drawers should be closed to ensure proper airflow and cooling within
the enclosure.
When fully opened, a drawer is designed to support its own weight, plus the weight of the DDICs.
Safety features:
•
To reduce the possibility of toppling, only one drawer can be open at a time.
•
The drawer locks into place when fully opened and extended. To reduce pinching hazards, two latches must be
released before the drawer can be pushed back into the drawer slot within the enclosure.
Power and data are sent via three baseplanes and two sideplanes. The direct-dock SATA version of the 5U
enclosure has one active and one passive sideplane, and has dual power paths, but only a single data path.
Each drawer can be locked shut by turning both anti-tamper locks clockwise using a screwdriver with a Torx T20
bit. The anti-tamper locks are symmetrically placed on the left-hand and right-hand sides of the drawer bezel.
Drawer status and activity LEDs can be monitored via two Drawer LEDs panels located next to the two drawer-pull
pockets located on the left-hand and right-hand side of each drawer.

Operator's (Ops) panel
Each of the enclosures supported by DS Series and DS EXP/D3284/DS EXP feature an Ops panel located on the
chassis left ear flange. The Ops panel for 2U and 5U enclosures are described herein.
2U enclosure Ops panel
The enclosure front panel has an Operator's (Ops) panel mounted on the left ear flange. A flexible cable connects
the Ops panel to the midplane. The Ops panel is a passive component: the midplane controls the panel, and the
IOMs control all the panel's functions. An integral part of the enclosure chassis, the Ops panel is not replaceable on
site. The Ops panel provides the functions shown in the illustration below and listed in the table. See also
