Page E-3
On the exposed portion of the processor board, find the header
marked
HDR4 ; it is in the upper-left area.
A shunt is attached to one of the pins on the HDR4 header.
Remove the shunt from the single header pin; then reinsert it so
that it covers both pins on the header.
Take the KF label from the Jack Numbering Labels Sheet, which is
packaged with the feature module, and fasten it to the wire manager
at the base of the module.
Installing the Control Unit Housing
(Release 2.1 and Earlier)
To install the control unit’s housing, follow the steps below.
Lay the front panel(s) face down.
If you are housing more than one carrier, connect the front panels
together.
a. Line up the arrows.
b. Slide the panels until the semicircles form a complete circle. See
Figure E-2
.
Connect the side panels to the front panel(s) in the same way.
Pick up the housing and place it on the control unit. If the system
has more than one carrier, make sure you hold the housing only
from the basic carrier side; otherwise, the housing can
disassemble.
a. Line up the wire clips that are attached to the carrier with the
recesses on the outside of the side panels.
b. Push back the panels until the clips hook over the tabs and rest in
the recesses.
