Basic Guidelines for Setting Up PoE Hardware
Positioning the Power Shelf
When positioning the power shelf for installation, please note the following important guidelines:
•
In free-standing (i.e., non-rack-mounted) installations, the power shelf cannot support the weight of a
switch chassis. As a result
, do not
attempt to stack an OS7700 or OS7800 chassis directly on top of the
power shelf at any time; damage to the power shelf chassis and its components may result. For free-
standing installations, the power shelf must either be placed on top of, or alongside, the switch chassis.
•
The cables connecting the power shelf to the chassis are approximately 49 inches in length. When
positioning the power shelf for installation, be sure that the unit is close enough to the OS7700 or
OS7800 chassis to provide a connection.
•
For rack-mounted installations, the power shelf may be installed either above or below the switch
chassis.
