The EPS is suitable for an office environment. It can either be
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
I
Ethernet, including the 100-meter limit on total cable length.
Locate the EPS so that you can connect cables easily.
I
Locate cables away from sources of electrical noise such as:
I
Radios, transmitters, or broadband amplifiers
I
Power lines
I
Fluorescent lighting fixtures
I
Make sure that no water or moisture can enter the EPS case. The unit
I
is not designed for outdoor use.
Make sure that air can flow freely on all sides of the EPS for proper
I
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
I
not place more than four units in a single stack. If you mount multiple
EPS units in a rack, this limit does not apply.
