Chapter 3 Installing the Cisco Global Site Selector 4490
Installing Your Unit
Installing the Chassis on a Workbench or Tabletop
When you install a Global Site Selector 4490 on a workbench or tabletop, ensure
that the surface is clean and in a safe location and that you have considered the
following:
• The chassis should be installed off the floor. (Dust that accumulates on the
floor is drawn into the interior of the chassis by the cooling fans. Excessive
dust inside the GSS 4490 can cause overtemperature conditions and
component failures.)
• There must be approximately 19 inches (48.26 cm) of clearance at the front
and rear of the chassis for accessing network cables or equipment.
• The GSS 4490 must receive adequate ventilation (it is not being installed in
an enclosed cabinet where ventilation is inadequate).
Follow these steps to install the GSS 4490 on a workbench or tabletop:
1. Remove any debris and dust from the tabletop or workbench, as well as from
the surrounding area. Also make sure that your path between the GSS 4490
and its new location is unobstructed.
2. Attach the rubber feet to the bottom of the chassis. The rubber feet have an
adhesive backing. Peel the protective tape off the adhesive and stick the feet
to the bottom of a clean chassis surface. Place one foot in each corner.
3. Place the chassis on the tabletop or workbench.
4. Ensure that no exhaust air from other equipment will be drawn into the
chassis. Also, ensure that there is adequate clearance at the front and rear of
the chassis.
