Inserting and removing power
supplies
The 1050 3U ICON frame accepts both main and redundant 1950 universal power
supplies which autosense input voltage between 90 and 253 volts and 50-60 Hz.
The power supply integral fan provides cooling for itself and all modules. There is
an 80mm deep space between the front of the modules and the door to allow the
cross flow cooling air to reach each module. However, the front door
must be kept
closed
for this cooling to function.
The adjustments on this power supply unit are set at the factory and should not
require re-adjustment.
Power supply insertion for the 1050 3U frame involves the following steps:-
•
slide the 1950 power supply into one of the available slots at the left of
the 1050 frame using the top and bottom PSU guides
•
tighten the captive screw at the rear of the frame
•
insert mains cable
•
repeat for the second power supply
•
ensure front door is closed
•
if only one PSU is fitted, use the left hand slot to encourage good air-flow
