3 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.
Note: The recommended spacing between bays is 10.0 inches (25.4 cm) when using
734A or equivalent and 735A or equivalent cables for cross-connect and equipment
In/Out cabling.
3.1.1
Positioning and Mounting of New Bay
Caution: A crated DSX-3 (DSX-4H-24) Rear Cross-Connect System bay weighs approximately
585 pounds (265 kg.). An adequately rated and secured block and tackle or overhead hoist must
be used while uncrating, positioning, and securing the 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 and Network Rack Installation Guide, ADCP-80-345.
