Installation and Replacement

Before you install the Vanguard 3400 Series, select a site for the device.
Choose a site that is within an appropriate distance of a power source. Depending on 

your application, and the country in which the Vanguard 3400 Series is to operate, 

the power source must be a grounded 110 to 220 Vac outlet.
Leave at least 2 inches (5 cm) of clearance in front of the front panel, to allow you to 

see the front panel LEDs, and 6-inches behind the unit for cable clearances (see 

Figure 3-2). For proper ventilation, leave 2 inches (5 cm) of clearance on the sides.
The site should be free of accumulated dust and environmental extremes. Refer to 

Vanguard 3400 Series devices should be used in environments designed for 

computers and electronic equipment. In areas susceptible to lightning, take 

precautions to prevent damage to electronic equipment. Contact your telephone 

company or an electronic accessories vendor for information on lightning protection 

equipment. Customers experiencing problems caused by surges from lightning have 

eliminated such problems by installing appropriate surge suppressors on power and 

data lines.

Minimum 2-inches (5 cm) Front

and 6-inches (15 cm) Rear

Note: Do not remove the rubber 

feet from the bottom of the 

unit. They allow for proper 

air flow.

Minimum 2-inches (5 cm)

on either side for ventilation.
