SGND & FRGND (JB5)
This strap pertains to the DTE interface, which is a 10-position
modular RJ-45 jack. In the connected (closed) position, this strap links
modular pin 5 (Signal Ground) and frame ground. In the open
(disconnected) position, pin 5 is "lifted" from frame ground.

4.0 INSTALLATION
This section describes the functions of the Model 1000R16 rack
chassis, tells how to install front and rear Model 1070RC cards into the
chassis, and provides diagrams for wiring up the interface connections
correctly.
4.1 THE MODEL 1000R16 RACK CHASSIS
The 1000R16 Rack Chassis (shown in figure 10, below) has
sixteen short range modem card slots, plus its own power supply.
Measuring only 3.5" high, the 1000R16 is designed to occupy only 2U
in a 19" rack. Sturdy front handles allow the 1000R16 to be extracted
and transported conveniently.
4.1.1 THE RACK POWER SUPPLY
The power supply included in the Model 1000R16 rack uses the
same mid-plane architecture as the modem cards. The front card of
the power supply slides in from the front, and the rear card slides in
from the rear. They plug into one another in the middle of the rack.
The front card is then secured by spring loaded thumb screws and the
rear card by conventional metal screws.
