SITE PREPARATION
2.1 OVERVIEW
Before installing a XC1000, the site where the XC1000 will be located must be
prepared to meet specific requirements. This chapter contains instructions for
preparing the site, including information about equipment location; cabling
and connector requirements; and procedures for installing external power, data
links, telephone wiring, and floor mounts. The sections about cabling assist in
determining cable lengths and connector locations. These procedures should
be accomplished before delivery of the XC1000.
The customer must supply the –48 Vdc power for the XC1000 –48 Vdc input-
power requirement.
Before preparing the site for installing the XC1000, refer to Chapter Ten for
descriptions of the XC1000 components. Determine the environmental and
power needs for XC1000 and observe all distance and length limitations
specified in this chapter. Use shielded cable for all telephone wiring and data
connections to external hardware. The customer is responsible for all equip-
ment not supplied by Octel and for meeting XC1000 site requirements.
