2U WALLMOUNT CABINET

Features

• The cabinet holds equipment designed to be placed in 2U (3.5", 8.9 cm) of vertical space in a 19" rack. The

cabinet’s mounting rails are near the top of the cabinet and face forward.

• You can take cables and power cords in and out of the cabinet through any of its four round side-mounted

cable knockouts (two on each side). These knockouts have grommeted edges to protect your cables and are

2" (5.1 cm) in diameter.

• It’s ventilated on both sides.

• Its door is lockable (but is shipped unlocked) and is hinged on the left. The door does not latch unless it is

locked. You should have received two keys for it, taped to the inside of the cabinet.

• Its enclosure is 16-gauge, powder-coated steel.

• Its outside dimensions are 20.3"H x 21"W x 4.9"D (51.6 x 53.3 x 12.5 cm). Its inside dimensions are only

slightly less, because of the thickness of the exterior steel.

• It weighs approximately 24 lb. (10.9 kg).

Installation

To mount a device in the cabinet, use the same hardware that you would use to mount the device in a 19" rack,

but mount the device so it hangs vertically (with its bottom against the back of the cabinet and its front panel

facing upward). Use the supplied cuphead screws to secure the device to its rackmount bracket.

Troubleshooting

If you have questions about installing the cabinet at your site, contact your site’s facilities or building

maintenance personnel, or consult a building contractor.

We offer a wide variety of cable management and other accessories that you might find useful for your

application. For more information, call Black Box Technical Support at 724-746-5500.
