16 CHAPTER 2: INSTALLING THE SWITCH ■ It is accessible and cables can be connected easily. ■ Cabling is away from sources of electrical noise. These include lift shafts, microwave ovens, and air conditioning units. Electromagnetic fields can interfere with the signals on copper cabling and introduce errors, therefore slowing down your network. ■ Water or moisture cannot enter the case of the unit. ■ Airflow around the unit and through the vents in the side of the case is not restricted (3Com recommends that you provide a minimum of 25 mm or 1 in. clearance). ■ The air is as free of dust as possible. ■ Temperature operating limits are not likely to be exceeded. It is recommended that the unit be installed in a clean, air-conditioned environment. It is always good practice to wear an anti-static wrist strap when installing network equipment, connected to a ground point. If one is not available, try to keep in contact with a grounded rack and avoid touching the unit's ports and connectors, if possible. Static discharge can cause reliability problems in your equipment. Rack-Mounting or Free-Standing The unit can be mounted in a 19-inch equipment rack using the supplied mounting kit, (see "Using the Mounting Kit" on page 16), or it can be free-standing. Do not place objects on top of the unit or stack. CAUTION: If installing the Switch in a free-standing stack of different size Baseline or SuperStack® 3 units, the smaller units must be installed above the larger ones. Do not have a free-standing stack of more than six units. Using the Mounting Kit The Switch is supplied with two mounting brackets and four screws. These are used for rack mounting the unit. When mounting the unit, take note of the guidelines given in "Positioning the Switch" on page 15. The Switch is 1U (1.75 in.) high and will fit in a standard 19-inch rack. CAUTION: Before continuing, disconnect all cables from the unit. Remove the self-adhesive pads from the underside of unit, if already fitted. To rack-mount the Switch: 1 Place the unit the right way up on a hard, flat surface with the front facing towards you. 2 Locate a mounting bracket over the mounting holes on one side of the unit. 3 Insert the two screws supplied in the mounting kit and fully tighten with a suitable screwdriver.

■
It is accessible and cables can be connected easily.
■
Cabling is away from sources of electrical noise.
These include lift shafts, microwave ovens, and air
conditioning units. Electromagnetic fields can
interfere with the signals on copper cabling and
introduce errors, therefore slowing down your net-
work.
■
Water or moisture cannot enter the case of the
unit.
■
Airflow around the unit and through the vents in
the side of the case is not restricted (3Com recom-
mends that you provide a minimum of 25 mm or 1
in. clearance).
■
The air is as free of dust as possible.
■
Temperature operating limits are not likely to be
exceeded. It is recommended that the unit be
installed in a clean, air-conditioned environment.
It is always good practice to wear an anti-static wrist
strap when installing network equipment, connected
to a ground point. If one is not available, try to keep
in contact with a grounded rack and avoid touching
the unit's ports and connectors, if possible. Static dis-
charge can cause reliability problems in your equip-
ment.
Rack-Mounting or Free-Standing
The unit can be mounted in a 19-inch equipment rack
using the supplied mounting kit, (see
“
Using the
Mounting Kit
”
on
page 16
), or it can be free-stand-
ing. Do not place objects on top of the unit or stack.
CAUTION:
If installing the Switch in a free-standing
stack of different size Baseline or SuperStack
®
3 units,
the smaller units must be installed above the larger
ones. Do not have a free-standing stack of more than
six units.
Using the Mounting Kit
The Switch is supplied with two mounting brackets
and four screws. These are used for rack mounting
the unit. When mounting the unit, take note of the
guidelines given in
“
Positioning the Switch
”
on
page 15
.
The Switch is 1U (1.75 in.) high and will fit in a stan-
dard 19-inch rack.
CAUTION:
Before continuing, disconnect all cables
from the unit. Remove the self-adhesive pads from
the underside of unit, if already fitted.
To rack-mount the Switch:
1
Place the unit the right way up on a hard, flat surface
with the front facing towards you.
2
Locate a mounting bracket over the mounting holes
on one side of the unit.
3
Insert the two screws supplied in the mounting kit
and fully tighten with a suitable screwdriver.
