A minor system fault is an error or event that
has little impact on system operation. The
system continues to operate.
A power supply fault indicates that one of the
power supplies is not providing power. The
MJR LED is also lit.
Information
When these LEDs are on, all three DS30
connections are working properly and the
cables are connected correctly. If one or more
LEDs are off, one of the following conditions is
present:
•
One or more connections to the switch
are 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.
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.
The power supply has its own LED:
•
OFF = system or power supply is off or
faulty
• Red/Amber = power supply is faulty or
cable is disconnected
•
Green = power supply is working correctly
and powered on
