Figure 10-1. RFL 9300 supervisor controller module
10.1 DESCRIPTION
The RFL 93B SV supervisor controller module (Figure 10-1) serves as the communications hub for the RFL
9300. The supervisor controller module generates the system clock, which is the "heartbeat" of all RFL 9300
activity. During power-up, the supervisor controller module controls the initialization of all modules in the RFL
9300. It also monitors and controls many system-wide functions, such as alarms and Direct Transfer Trip (DTT)
signals.
10.2 CONTROLS AND INDICATORS
Figure 10-2 shows the location of all controls and indicators on the RFL 93B SV. These controls and indicators
are described below. Those described as front-panel controls are accessible with the RFL 93B DISPLAY in-
stalled in the RFL 9300 chassis; all others are only accessible when the RFL 93B SV is removed from the chas-
sis, or is on a card extender.
LED INDICATORS
DS1 SYS ALARM - Front-panel indicator; lights red when a system-wide problem is detected.
DS2 TX/RX ALARM - Front-panel indicator; lights red when a communications failure is detected.
