3com 3C35004 System Processor


Status LEDs

LED Color Description
PWR Green The system processor is receiving power.
RUN Blinking Green
Steady Green
The system processor is operating.
The system processor is running diagnostics.
SYS Steady Yellow
Blinking Yellow
The system processor failed at power up.
A hardware/software mismatch has occurred.
INS Yellow The system processor is not fully seated.
PS1 Yellow The first power supply is out of specification.
PS2 Yellow The second power supply is out of specification.
FAN Yellow The fan has slowed or shut down.
TEMP Yellow The system has overheated.
SERVICE Yellow System service mode is active.
PCMCIA INS Green A PCMCIA card is inserted in the system.

System Diagnostics — LED Activity

When you first power up the system, the system processor PWR LED and RUN LED light green, indicating that the system is receiving power and running diagnostics. After the system diagnostics are successfully completed, the RUN LED blinks green, indicating that the system is operating. If the SYS LED lights yellow, the system processor has failed at power up.

You can view messages displayed during power-up diagnostics if you connect a terminal, workstation, or PC with terminal emulation software
