Description
The IMM2 lights this LED and the fault LED when
microprocessor 4 is defective.
The IMM2 lights this LED and the fault LED when
there is a power fault on one of the power rails.
The IMM2 lights any of these LEDs and the fault LED
when any DIMMs 1 – 48 are defective.
This LED lights when there is Ethernet activity on port
0 of LOM controller 1.
This LED lights when there is Ethernet activity on port
1 of LOM controller 1.
This LED lights when there is Ethernet activity on port
0 of LOM controller 2.
This LED lights when there is Ethernet activity on port
1 of LOM controller 2.
This LED lights when port 0 on LOM controller 1 is
connected to the network.
This LED lights when port 1 on LOM controller 1 is
connected to the network.
This LED lights when port 0 on LOM controller 2 is
connected to the network.
This LED lights when port 1 on LOM controller 2 is
connected to the network.
This LED lights when power to LOM controller 1 is on
and working properly.
This LED lights when power to LOM controller 2 is on
and working properly.
This LED lights when there is an overcurrent fault on
one of the 12 V power rails.
This LED lights when there is activity on the RTMM.
This LED lights when there is activity on the IMM2.
The IMM lights this LED and the fault LED when there
is a problem with SAS backplane 1.
The IMM2 light this LED and the fault LED when there
is a problem with SAS backplane 2.
The IMM lights this LED and the fault LED when there
is a fault with the link between the SAS controller and
SAS Port 0 on SAS backplane 1.
The IMM lights this LED and the fault LED when there
is a fault with the link between the SAS controller and
SAS Port 1 on SAS backplane 1.
The IMM2 lights this LED when there is a fault with the
link between the SAS controller and SAS port 0 on
SAS backplane 2.
