OVERVIEW
This section provides service upon receipt instructions.
. Normally, you will receive your TD-1337(V)/G already installed in a rack with proper cabling connected.
However, if you have to plan a TD-1337(V)/G installation, refer to paragraphs 2-2 through 2-5
which contain physical and electrical interface requirements.
. Unpacking instructions are contained in paragraphs 2-6 and 2-7.
. Refer to paragraph 2-16 for procedures to install a TD-1337(V)/G.
2-1. Site and Shelter Requirements.
The TD-1337(V)/G is designed to be installed in an equipment rack and operated in the environment of
a shelter or a fixed plant. Normally, you will receive your TD-1337(V)/G already installed in a rack with
proper cabling connected. In this case, appropriate physical and electrical interface requirements were con-
sidered and accounted for during design of the rack. Use the information in paragraphs 2-2 through 2-5
if you have to plan a TD-1337(V)/G installation.
2-2. Power Requirements.
The TD-1337(V)/G requires an external power input of 115v (103.5 to 126.5v), 45 to 440 Hz, 140 watts
maximum.
2-3. Rack Mounting Requirments.
The TD-1337(V)/G is built for mounting in a 19-inch equipment rack. The following conditions must be
considered in the installation planning.
a. Mounting S/ides. The TD-1337(V)/G is slide mounted in an equipment rack. One set of inner-channel
slides and one set of matching outer-channel slides are required to support the TD-1337(V)/G in a rack.
The inner-channel slides SM-D-777131-6 (right) and SM-D-777132-6 (left) come installed on a TD-1337(V)/G.
The outer-channel slides SM-D-777131-5 (right) and SM-D-777132-5 (left) are not supplied with a TD-
1337(V)/G. These slides must be obtained and mounted in the rack.
b. Rack Cooling System. The rack cooling system must be capable of supplying at least 50 cfm
(1.42 cu m/min) of air flow for cooling the TD-1337(V)/G. This air is directed into the side panel air inlet
and over the power supply. The temperature of the cooling air must not exceed 145F (62.8C).
