INSTALLATION

The 7707IT series modules come with a companion rear plate that has multi-pin removable terminal block
connections, and an SC/PC (shown), ST/PC or FC/PC optical connector. For information on mounting the
rear plate and inserting the module into the frame see section 3 of the 7700FR chapter. The following
diagram shows four rear plate options.

OPTICAL CONNECTIONS



The 7707IT modules are designed to work with single-mode or multi-mode optical
fiber depending on the version ordered.



The CARD ID jumper must be configured in order to establish a robust optical link
between the two 7707IT modules. (See section 6.1)
