rack-mounted in a standard 19-inch equipment rack (for example, in a

 

wiring closet or equipment room) or placed free-standing on a desk,

 

table, or counter. Both the 12-port and 24-port EPS packages (3C10220

 

and 3C10222 respectively) contain a rack-mounting kit with two

 

mounting brackets and six screws.

When you select a site for the EPS:

■Always follow the appropriate configuration practices for Fast Ethernet, including the 100-meter limit on total cable length.

■Locate the EPS so that you can connect cables easily.

■Locate cables away from sources of electrical noise such as:

■Radios, transmitters, or broadband amplifiers

■Power lines

■Fluorescent lighting fixtures

■Make sure that no water or moisture can enter the EPS case. The unit is not designed for outdoor use.

■Make sure that air can flow freely on all sides of the EPS for proper cooling. 3Com recommends that you provide a minimum of 25 mm (1 in.) clearance on each side of the unit.

■If you use more than one EPS and place them on a table or desk, do not place more than four units in a single stack. If you mount multiple EPS units in a rack, this limit does not apply.
