• Reduced air flow — Install the port extender in the rack so that the front-to-back airflow (I/O ports to
PSU) is not obstructed.
• 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).
