• Grounding wrist strap (included)

• Phillips screwdriver

• Flat-blade screwdriver

• Serial cable

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 

 for minimum clearance 

requirements. No clearance is necessary at the top or 
bottom of the chassis.

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.
