NOTE: The QXS-484 12G systems ship with no drives installed (weight). Drives are shipped within
two boxes containing 42 drives within each box.

Figure 6 provides an image of the 84-drive chassis (drive slots view) with the drawer open. There are

a total of 84 drive slots in the two drawers.

• Drawer 0 has drive slots 0-41 (42 drives can be installed)

• Drawer 1 has drive slots 42-83 (42 drives can be installed)

NOTE: Figure 6 displays the front of the drawer on the left side of the illustration (callout 1). The

back of the drawer is on the right side of the illustration (callout 3).

This section includes the following information:

• Standard Cabinet

• Cabinet Height

• Cabinet Vertical Support Rails

• Cabinet Configurations with Chassis and Drives

Standard Cabinet

Figure 7 provides an image of a standard cabinet which includes locations of the following:

• Front door

• Rear door

• Vertical support rails

• Air vent

Figure 7 Standard Cabinet

QXS System and Cabinet Information 5

Standard features of the cabinet include:

• Front and rear door that can be closed and locked

• Vertical rails, with mounting holes, to allow installation of storage

• 40U high cabinet and 19 inches/48.3cm wide

• Four rolling coasters/wheels

• Four leveling pads (bottom of cabinet)

• A stabilizing foot (after installation of permanent location)

• Access for storage cabling

• AC or DC power source (2 each)

WARNING! Risk of bodily harm and/or injury. Comply with the following:

• Always populate the cabinet from bottom to top to prevent tipping.

• If a cabinet must be moved, use adequate personnel and/or a forklift to relocate the cabinet.

• Push the cabinet from the front when moving.

• A fully populated cabinet can weigh almost 3000 pounds (1360.777kg).

• Cabinets are hard to move, even on a flat surface/floor.

• If moving a cabinet on an incline, always remove the top-half storage arrays/devices to prevent

from tipping.

NOTE: Install the applicable storage rack on the cabinet support rails, then install the
chassis/expansion storage unit, and then populate the unit with applicable drives (HDDs or SSDs).

Ensure to place the cabinet in a location that allows sufficient space to maintain and service (remove
and replace parts) the applicable units within the cabinet.

Cabinet Height

Cabinets heights might vary. A common cabinet is 40U high.

• A height of 1U equals 1.75-inches (44.45-mm).

• So, a 40U cabinet will have 70 inches (1778 mm/1.778 km) of storage space.

CAUTION: Ensure that the cabinet weight (populated with chassis, drives, units) does not exceed
the floor loading specifications.

You should record the total weight of your applicable cabinets (with contents). Use this information
to check floor loading restrictions and/or elevator weight restrictions.
