Controls and Indicators
3.1
Chassis Indicators
The DTS1 has four LED status indicators (Figure 3.1) on the bottom of the front panel:
•
POWER
•
FAULT
•
KEY LOADED
•
DRIVE CAPACITY
The brightness of the chassis LEDs can be independently set from 0 to 100% brightness. This
accomplished by changing the duty cycle of the power applied to the individual LEDs. The CLI
ledctrl command is used in association with -s option to select the individual LED and -d option to
select its duty cycle. See paragraph 12.3.14

3.1.1
POWER LED
This LED will illuminate green shortly after the 28 volt supply is switched on. This LED remains
illuminated while power is supplied.
3.1.2
FAULT LED
This LED may illuminate for a short time after power is applied (during booting) and will extinguish
if the Built-In-Test (BIT) passed. The periodic BIT will illuminate this LED if it detects an anomaly
such as an out of tolerance voltage level. If an error or failure has occurred in the encryption
hardware or software the FAULT LED will light and no encrypted data can be transferred. If the
FAULT LED remains on, try:
•
Restarting the DTS1
•
Reseating the RMC
section for possible causes and solutions. Contact Curtiss-Wright
Defense Solutions if the fault indications persist.
3.1.3
KEY LOADED LED
When this yellow LED is illuminated, it indicates that the encryption key has been successfully
loaded to the RMC.
3.1.4
DRIVE CAPACITY LEDs
NOTE
The capacity LEDs only correlate to the entire unpartitioned physical RMC. On partitioned RMC
modules the LEDs are not valid. See paragraph 12.3.22
to acquire disk and partition
capacity information.
