Cell Site Hardware LED Descriptions
RCU,
SBRCU
x Red Lighted during the self-test initiated
upon powerup or after a reset and
goes off after successful comple-
tion of the self-test; lighted during
normal operation if the RCU/
SBRCU has a board error or is
insane.
Yellow Lighted during non-volatile memory
(NVM) update.
Green Lighted when the RCU/ SBRCU is
transmitting.
RTU
x Red Lighted during the self-test initiated
upon powerup or after a reset and
goes off after successful comple-
tion of the self-test; lighted during
normal operation if the RTU has a
board error or is insane.
Yellow Lighted during NVM update.
Green Lighted when the RTU is transmit-
ting.
RFG
xx Red Upon powerup, lights for approxi-
mately 4 to 6 minutes while oscilla-
tor is warming up and then goes off;
during normal operation, lighted red
LED indicates an oscillator failure
or, for a crystal oscillator, that the
oscillator may be in an unlocked
state.
Yellow For a rubidium-crystal oscillator
combination, indicates that the
backup crystal oscillator is
phase-locked to the rubidium oscil-
lator; for a two-rubidium oscillator
combination, indicates that the
backup rubidium oscillator is ready
for operation.
Green Indicates that the oscillator is active.
