Mounting the Switch
Important.
Two people are required when lifting the chassis. Due to its weight, lifting the chassis unas-
sisted can cause personal injury. If you need to move the switch, be sure to power it down and remove all
modules and power supplies. For instructions on removing CMM or NI modules, refer to
“Network Interface (NI) Modules.”
For instructions on removing power supplies, refer to
Note.
Due to their weight and airflow requirements, OS7700 and OS7800 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.

Note.
Never obstruct the air intake vents located at the bottom-front and bottom-sides of the chassis
or
the
fan unit’s air output vents located at the rear of the chassis. Clearance is not required at the top and bottom
of the chassis.
