Part of an Indigo 4 upper frame showing the use of full and half size EMC covers and the use of single,
double and quad rear connectors
Note:
In order to accommodate the connectors of some full height (quad) rear modules such as
the RM02, RM10 and RM19, special retaining bars without a central captive screw
should be used. The centre of the bar is then retained with separate M3 x 8mm screw.
Warning:
To maintain product safety and EMC compliance the rear of the frame should be
filled with Crystal Vision rear connectors and/or EMC covers and held in place
with retaining brackets before power is reapplied.
2.8 Indigo power supplies
The power supply module available for the Indigo 4 4U frame is the 160W rated PSU-
160i. The Indigo 4 will be fitted with at least two power supply modules.
PSU-160i – top view
Monitoring power supply status
A signal from the each of the power supplies is routed through the frame wiring to the
front panel electronics. This allows an indication by the PSU LEDs of the status of the
installed power supplies.
A fault condition is indicated when the corresponding LED is red and a normal condition
when it is green/yellow. If a PSU is removed for maintenance the corresponding LED will
be un-lit.
