Troubleshooting
If you have any problems with your system, please check the following items prior to
calling for support.
No power to PC blade
• Check the power button on the front of the PC blade.
• Verify that the power circuit to the chassis is operational.
• Check all power strips, UPS, and extension cords to make sure they are in
working order.
No video or link lights at desktops and no power to blades
• R4300: Have a qualified service technician check the fuse.
Chassis power does not come on
• R4300: Have a qualified service technician check the fuse.
Video link shows red at blade but green on C/Port
• The switch matrix in the R4300 chassis may be in a partially switched condition.
Switch the affected blade to the Admin C/Port and then back.
Fiber Optic Troubleshooting
No video and/or digital link present
• Check all the C/Port and fiber optic cables and their associated jacks for signs of
damage or wear. Replace any suspicious cables with new, commercially
manufactured cables and test the remaining cables with a quality tester.
• Non-commercial cables are frequently the culprits when equipment fails to work
properly. For this reason, ClearCube strongly discourages the use of
Non-commercial cables.
• Check that the power supply brick is the proper one for the Fiber C/port. It should
have a rated output of +5 VDC, 7 A; –5 VDC, 1 A. The power supply for the
standard C/Port and the MVX does not work with the Fiber C/Port.
CAUTION: DOUBLE POLE/NEUTRAL FUSING
The DIM employs fuses in both the neutral and hot lines.
