Server LEDs
The LEDs indicate the state of your server and can help you troubleshoot
startup problems. The following tables provide useful information on the
external and internal LEDs.
External LEDs
Description Information
MPB96 DS30 link LEDs
(three green LEDs located
on the card bracket and
visible from the back of the
server) When these LEDs are on, all three DS30 connections are working
properly and the cables are connected correctly. If one or more
LEDs is off, one of the following conditions is present:
• One or more connections to the switch is interrupted. Check
each of the three branches of the DS30 cable for faults, or
replace the cable.
• An MGate card in the switch is defective.
Blue LED at the back of the
server This LED is currently not used. The blue LED comes on only for a
moment at server startup.
NIC LEDs Each network interface card (NIC) has two LEDs:
• The upper LED shows that the network cable is connected.
• The lower LED blinks to indicate data transfer.
Internal LEDs
Description Information
MPB96 board LEDs The three red LEDs at the top of the MPB96 board are visible
through the grill at the back of the server.
• The PCI FPGA Done LED (the closest to the card I/O bracket)
comes on at startup and turns off immediately. This indicates
that the board works properly and was detected correctly by
the system. If this LED stays on after the startup, the card is
defective and must be replaced.
• The DSP FPGA Done LED comes on at startup and stays on
