Site Preparation
Environmental Requirements
OmniSwitch 6900 switches have the following environmental
and airflow requirements:
• The installation site must maintain a temperature
between 0° and 45° Celsius (32° and 113° Fahrenheit)
and not exceed 85 percent maximum humidity (non-
condensing) at any time.
• Be sure to allow adequate room for proper air
ventilation at the front, back, and sides of the switch.
Refer to “Mounting the Switch” on page 5 for
minimum clearance requirements. No clearance is
necessary at the top or bottom of the chassis.
Electrical Requirements
OmniSwitch 6900 switches have the following general
electrical requirements:
• Each switch requires one grounded electrical outlet for
each power supply installed in the chassis.
OmniSwitch 6900 switches offer both AC and DC
power supply support. Refer to the OmniSwitch 6900
Hardware Users Guide for more information.
• For switches using AC power connections, each
supplied AC power cord is 2 meters (approx. 6.5 feet).
Do not use extension cords.
Redundant AC Power. It is recommended that each AC
outlet resides on a separate circuit. With redundant AC, if
a single circuit fails, the switch’s remaining power
supplies (on separate circuits) can remain operational.
• For switches using DC power, refer to the OmniSwitch
6900 Hardware Users Guide for more information.
