Controls and Indicators
Revision 0.0
The function of the ILE module indicators is as follows.
•
P (GREEN). This LED turns ON whenever 28VDC is applied to the ILE module.
•
F (RED). This LED turns ON whenever the ILE module has a fault condition.
•
S (YELLOW). This LED turns ON whenever the encryption key(s) are loaded into the ILE
module.
The ZEROIZE button is used to zeroize (delete) the encryption keys loaded in the ILE module.

FSM-C Module Controls / Indicators
NOTE
The F (RED) LED turns on until after the CNS4 has booted up, started communicating, and loaded
encryption keys into the FSM-C module.
The FSM-C module (Figure 3.3) has three LED status indicators: P, F, and S. During normal
operation, P and S will be ON; F will be off. The illumination level of the LEDs is preset and non-
adjustable. The function of these indicators is as follows.
•
P (GREEN). This LED turns ON when 28VDC is applied and FSM-C module initialization has
occurred.
•
F (RED). This LED turns ON whenever there is a Built-In Test (BIT) failure or operational
problem related to the FSM-C module. If the problem is also related to the CNS4, the S0 will
turn ON.
•
S (GREEN). This LED turns ON whenever the FSM-C module is active (reading / writing data).
The REMOVAL REQUEST button is disabled in this configuration.
