Administrator Guide

• Reliable earthing — Maintain reliable earthing of rack-mounted equipment. Pay particular attention to

supply connections other than direct connections to the branch circuit; for example, use of power

strips.

• Rack mounting — Do not mount the port extender with the rear panel facing in the downward

position.

Installing a Rack Mount Tray (Optional)

You can use a rack mount tray to support the weight of the C1048P in a 4-post rack. You must order the

tray separately.

To install a rack mount tray in a 4-post rack, follow the instructions provided with the tray kit. Decide on

the desired height to mount the switch in the rack. Position the tray at that height and tighten it to the

rack posts using the screws shipped with the tray (items 1 to 4 in Figure 5).

Installing the C1048P in a Rack

You can install the C1048P in a 1 RU 4-post front-rack or 1 RU 2-post (flush and center) rack

configuration. Although the procedure in this section describes C1048P installation in a 1 RU 2-post

front-rack configuration, follow the same steps to install a C1048P in a 1 RU 4-post rack.

WARNING: Never mount the C1048P in a rack that is suspended under a table or desk, or

attached to a wall.
