SSU-2000e Status LED Indicators
All modules used in the SSU-2000e main chassis and in the optional SDU-2000e
expansion chassis contain status LED indicators that provide a visual indication of
module status. The Communications module provides both system and individual
module status whereas all other modules provide individual module status only. For
more information on individual module status LED indicators, refer to
Turn-Up Procedures, on page 85, and
Chapter 7, Input Module Reference Data,

SSU-2000e Operating Controls
The SSU-2000e contains three hardware operating controls:
Two DCE/DTE select switches associated with the three EIA-232 ports. One
switch is located on the front of the Communications module and the second
switch (S1) is located on the SSU-2000e connection panel. The DTE position is
for connection to a PC and the DCE position is for connection to a modem.
Reset (RST) switch on the Communications module.
