Rack Mounting

Before rack mounting the switch, pay particular attention to the following factors:

•Temperature: Since the temperature within a rack assembly may be higher than the ambient room temperature, check that the rack-environment temperature is within the specified operating temperature range. (See page C-1.)

•Mechanical Loading: Do not place any equipment on top of a rack-mounted unit.

•Circuit Overloading: Be sure that the supply circuit to the rack assembly is not overloaded.

•Grounding: Rack-mounted equipment should be properly grounded. Particular attention should be given to supply connections other than direct connections to the mains.

To rack-mount devices:

1. Attach the brackets to the device using the screws provided in the Bracket Mounting Kit.

Figure 3-2. Attaching the Brackets

2. Mount the device in the rack, using four rack-mounting screws (not provided).
