Inserting and removing power supplies
The PSU-160i power supply can be inserted and removed while the system is powered
without damage. However, this must be done quickly as there will be no forced convection air,
as the PSU fan assembly has to be removed.
To gain access to the Indigo PSUs proceed as follows:
•
If possible, power down the frame
•
Pull down the front panel using the black knobs at either side of the panel
•
Release the two captive screws to the left of the PSU fan
•
Remove the fan assembly by applying sideways pressure on the fan assembly outwards
and towards the right hand frame side
Note:
Take care not to damage the panel ribbon cable when removing the fan
assembly.
Once the fan assembly has been pulled backwards to free the fan connector plugs, the PSU
fan will stop and the front panel PSU FAN LED will change from green to red.
Removing the PSU fan assembly
Lower PSU-160i – front view
In addition to the PSU and fan LEDs on the front control panel, there is also a red error LED
on the PSU. This LED will flash slowly if there is no fan speed signal present on the fan
connector SK1 when the PSU fan assembly is removed or if the PSU fan stops.
