When THEN
•
check each of the three individual
branches of the DS30 cable for faults, or
replace the cable.
•
check for a faulty MGate card (NTRB18CA)
in the switch.
Blue LED
The blue LED in the back of the 703t system is not used in CallPilot.
It comes on for only a moment during a server reboot.
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.
RAID controller LED states
Refer to "Slot definition and numbering" (page 172) for the slot position
of the RAID boards in your server.
