How to Choose a Site
How to Choose a Site
Introduction Before you install a Vanguard 7300 Series router, select a site for the device. The site
should be free of accumulated dust and environmental extremes. Refer to
Appendix A, Specifications, for detailed dimensions.
Power
Requirements Choose a site that is within an appropriate distance (approximately six feet) of a
power source. Depending on your application and the country in which the Vanguard
7300 Series product is to operate, the power source must be a grounded 100 to 240 V
AC outlet, 60 to 50 Hz.
The Vanguard 7300 Series DC input version specifications are -40VDC to -72VDC
input (-48 DC version) with a maximum input current at -40VDC. See Appendix A,
Specifications, for specific electrical information.
Air and Cable
Clearances Allow at least 20 inches (50.7 cm.) of clearance in front of a Vanguard 7300 chassis
to open the door, to attach cables, and to replace cards. Leave at least
20 inches
(50.7 cm) behind the unit for card removal, cable clearance, and air circulation.
Caution
Vanguard Managed Solutions 7300 series products 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 can eliminate such problems by installing appropriate surge suppressors on
power and data lines connected to Vanguard 7300 Series products.
Rackmount Weight
Consideration To avoid hazards arising from uneven mechanical loading of the rack, plan your
installation so that (within the limitations of equipment and cabling) the weight of
the equipment is evenly distributed in the rack. Mount the heaviest units towards the
bottom of the rack.
