Rack-Mounting or Free-Standing 19
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 mounting kit, 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, you should take note of the
guidelines given in “Positioning the Switch”
on page 18.
The Switch is 1U (1.7 inches) high and will fit in a
standard 19-inch rack.
CAUTION: Disconnect all cables from the unit before
continuing. Remove the self-adhesive pads from the
underside of the 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.
