SeRF Module LEDs
NOTE:
The SeRF Module LEDs automatically enter a LED Roll Test sequence (cycle through its colors) when the
SeRF FPGA is loaded (approximately 4 minutes after initial power up) or when a SeRF synthesizer failure
occurs. The LED Roll Test sequence takes approximately two seconds to complete, and cycles the
ALARM, SYNTH, and STATUS LEDs, after which the LEDs begin normal operation. Additionally, an active
SeRF Synthesizer failure causes the same LED sequencing approximately every minute until the SeRF
failure clears.
LED
LED Color Description
POWER
• GREEN • Power OK and operating properly
• RED
• Power supply out of tolerance
• OFF
• No power present
STATUS
• GREEN
• RED
• No alarm for the SeRF II Module
• Initial bootup sequence and should become GREEN within 1 minute;
if RED after bootup, a Major alarm exists for the SeRF Module
SYNTH
• GREEN • Locked
• RED
• Unlocked or is in initial bootup sequence
ALARM
• GREEN • No major alarm is present in the PRU or in any downstream unit
• RED
• Initial bootup sequence, or a major alarm is present in the PRU or in any downstream unit
