Site Preparation
Environmental Requirements
OmniSwitch 7700/7800 switches have the following environ-
mental and airflow requirements:
• The installation site must maintain a temperature
between 0° and 45° Celsius (32° and 122° Fahrenheit) and
not exceed 95 percent maximum humidity (noncondens-
ing) at any time.
• Be sure to allow adequate room for proper air ventila-
tion at the front, back, and sides of the switch. Refer to
“Mounting the Switch” on page 7 for minimum clearance
requirements. No clearance is necessary at the top or
bottom of the chassis.
Electrical Requirements
OmniSwitch 7700/7800 switches have the following general
electrical requirements:
• Each switch requires one grounded electrical outlet for
each power supply installed in the chassis (up to three for
OS7700 switches; up to four for OS7800 switches).
OmniSwitch 7700/7800 switches offer both AC and DC
power supply support. Refer to the Hardware Users Guide
for more information.
• For switches using AC power connections, each
supplied AC power cord is 2 meters (approximately 6.5
feet) long. Do not use extension cords.
Redundant AC Power. If possible, it is recommended
that each AC outlet resides on a separate circuit. With
redundant AC, if a single circuit fails, the switch’s remain-
ing power supplies (on separate circuits) will likely be
unaffected and can therefore continue operating.
• For switches using DC power, refer to the Hardware
Users Guide for more information, including installation
guidelines.
