Maintenance
The error LED will light up continuously if power rail levels are outside operational limits.
When the fan speed signal is present and power rails are normal the error LED is unlit.
Removing a PSU
To remove a PSU proceed as follows:
•
Apply sideways pressure on the PSU handle towards the right and remove the PSU by
pulling it forward
•
Take care when removing the lower PSU not to damage the panel ribbon cable
Caution:
There are no user serviceable parts inside the power supply module covers. The
safety covers should not be removed even when the module is disconnected.
Note:
Check that the 2/1 switch behind the control panel is set correctly for the number
of PSUs installed to prevent redundant PSU warnings.
Inserting a PSU
To insert a PSU proceed as follows:
•
Check that any second power supply is the same type as already fitted
•
Offer up the PSU to the frame guide rails – it may help to turn the lower PSU handle fully
outwards to clear the panel hinge
•
Carefully push the PSU all the way into its socket
Notes:
PSU modules should only fit into the PSU slots behind the PSU fan assembly.
Do not attempt to fit a PSU into a video or audio module slot.
Check that the 2/1 switch behind the control panel is set correctly for the number
of PSUs installed to prevent redundant PSU warnings.
Fitting the fan assembly
To replace the PSU fan assembly proceed as follows:
•
Offer up the fan assembly ensuring that the two lugs fit into two slots in the right hand
side of the frame just in front of a plastic stop
•
Carefully move the fan assembly into position ensuring that the two PSU fan jacks fit into
the PSU jack sockets (SK 1)
•
Take care not to damage the panel ribbon cable
•
Tighten the two captive screws to the left of the PSU fan ensuring that they are not too
tight to be undone without a screwdriver.
•
If the unit was unpowered it may now be powered and tested
