Installing the Hardware

When the power supply is pulled out far enough (about
10”), place your other hand under the power supply casing
to support its weight.

Continue pulling the power supply out until it is
removed from the chassis.
11
Set the power supply aside on a clean, static-free
surface. You will need to re-install it later.
12
Remove all remaining power supplies by repeating
steps 7 through 11.

Continue to “Lifting the Chassis” below.
Lifting the Chassis
Once its weight has been reduced by removing the power
supplies, the chassis can be lifted from the packaging material
and moved to the location where it is to be installed (see
important note below).
Important.
Two people are required when lifting the
chassis. Due to its weight, lifting the chassis unassisted
can cause personal injury.
Once the chassis has been removed from the packaging,
continue to “Mounting the Switch” below.
Mounting the Switch
Note.
Due to their weight and airflow requirements,
OmniSwitch 7700/7800 switches cannot be wall-mounted.
Airflow Considerations
Be sure that your switch is placed in a well-ventilated, static-
free environment. Always allow adequate clearance at the
front and sides of the switch, as well as behind the switch’s fan
unit (located at the top-rear of the chassis). The following top-
view diagram shows recommended minimum clearances for
adequate airflow.
