Interpreting internal LEDs
This section describes LED states visible inside of the 703t server
cabinet.
MPB96 LED states
There are three LEDs on the top of the MPB96 board. They are visible
even from outside the server cabinet, through the rear grill.
“PCI FPGA Done” LED (closest to the I/O card bracket)
This LED should go ON at power up and then OFF right away. This
LED activity indicates that the board is working properly and was
correctly detected by the system.
If the LED stays ON after power up, the card is faulty, and you must
replace the board.
“DSP FPGA Done” LED
This LED comes on at power up and stays ON until the CallPilot drivers
are loaded just before the diagnostic screen starts.
If this LED stays ON after the system has booted in the operating system
and the CallPilot diagnostic screen has started, either the board is faulty
or there is a problem with the CallPilot DSP and Windows Bus drivers.
“CTbus FPGA Done” LED (furthest from the I/O card bracket)
This LED works in tandem with the “DSP FPGA Done” LED, and
should go on and off at the same times.
