4.1.3.9 SWITCH-MONITOR/ALARMS
Pressing this key brings up a series of menus on the LCD that allow monitoring of major and minor
alarms and control of alarm masking for the RCS20.
4.1.3.10 SWITCH-TEST
Pressing this key brings up a series of menus on the LCD that allow testing of the RCS20
configurations and connections.
4.1.4 Front Panel LCD Indicators
There are sixteen (16) LEDs on the RCS20 front panel to indicate the selected LCD menu tree and
current switch status. The color of the illuminated LEDs on the front panel indicate overall switch
status according to the following key: An illuminated green LED indicates normal operation. An
illuminated yellow LED indicates a condition that is not proper for normal operation, however, all
satellite channels are currently on-line. An illuminated red LED indicates that the RCS20 was
unable to provide redundancy protection for a satellite channel, and at least one channel is off-line.
For the purposes of this discussion, the LEDs are separated into two major groups, MENU LEDs
and SWITCH STATUS LEDs. The Menu LEDs are those LEDs immediately next to the front panel
keys in the MODEM and SWITCH groups, and the SWITCH STATUS LEDs are those in the
SWITCH STATUS group (see Table 4-2).
Menu LED Indicators (Green)
Each Menu LED corresponds to the MODEM group or SWITCH group key located to the right of the
LED. When lit these LEDs indicate which menu tree is currently active on the LCD. For example,
if the SWITCH-TEST LED is illuminated, then the LCD is displaying one of the menus that allow
control of RCS20 test modes.
