SYSTEM STATUS INDICATORS AND THE ACO SWITCH
When the RFL 9508D front door is closed, four LED indicators are visible. These LEDs are labeled:
POWER, NORMAL, ALERT, and ALARM, as shown in Figure 8-6, and indicate the operational
status of the 9508D chassis at a glance. Table 8-2 gives a description of these indicators and also
includes a description of the power supply fail indicator and the alarm cutoff switch.
