Rack loading — Overloading or uneven loading of racks may result in shelf
or rack failure, causing damage to the equipment and possible personal
injury. Stabilize racks in a permanent location before loading begins.
Mount components beginning at the bottom of the rack, then work to the
top. Do not exceed your rack load rating.
•
Power considerations — Connect only to the power source specified on
the unit. When you install multiple electrical components in a rack, ensure
that the total component power ratings do not exceed circuit capabilities.
Overloaded power sources and extension cords present fire and shock
hazards.
•
Elevated ambient temperature — If you install the system in a closed rack
assembly, the operating temperature of the rack environment may be
greater than room ambient. Use care not to exceed the 50 degrees C
maximum ambient temperature of the switch.
•
Reduced air flow — Install the port extender in the rack so that the front-
to-back airflow (I/O ports to PSU) is unobstructed.
•
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 at which you want 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).
