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.
