INSTALLATION
3.1
Bay Installation/Expansion
Installation
of cross-connect system hardware may consist of installation of an entire new cross-
connect
system bay or expansion of an existing bay. Location of a new bay must take into
consideration
its distance to other equipment, other system bays, and cable type.
3.1.1
Positioning and Mounting of New Bay
Set
the bay in its assigned position, and secure it to the floor and to adjacent bays using
appropriate
hardware. Also secure it to overhead support if required. Refer to the Unequal
Flange
Rack Installation Instructions (ADCP-80-345).

Note:
The recommended spacing between bays is 25.4 cm (10.0 inches) when using 734A
or
equivalent and 12.7 cm (5.0 inches) when using 735A or equivalent cables for cross-
connect
and equipment IN/OUT cabling.
Caution:
A crated DSX-3 (DSX-4U-24) Rear Cross-Connect System bay weighs approximately
265
kg (585 pounds). An adequately rated and secured block and tackle or overhead hoist must
be
used while uncrating, positioning, and securing the bay.
