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
