How to Install the Switch in a Rack
When rack mounting the switch, pay particular attention to the following factors:
◆ Rack Types: You can use any standard EIA 19-inch equipment rack with either
two or four posts. The bracket hole pattern should be spaced 1U (1.75 in. or
4.45 cm) apart.
◆ Rack Stability: Whenever possible, secure the rack to the building ceiling or
floor, particularly if you are located in a region where earthquakes are common.
◆ Rack Planning: When installing equipment in a rack, first plan how units can
be best arranged. Try to always mount the heaviest equipment at the bottom
of the rack.
◆ Tem peratur e: 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 “Switch
Cooling Requirements” on page 26.
◆ 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.
Rack-Mounting Items Before you start to rack-mount the switch, be sure to have the following items
available:
◆ Four mounting screws for each device you plan to install in a rack—these are
not included. Be sure to use the rack mounting screws that are supplied with
the rack.
◆ A screwdriver (Phillips or flathead, depending on the type of screws used).
