Introduction
1 Introduction
The Indigo range comprises of four frame types, 4U frames for up to 24
modules, 2U frames for up to 12 modules, 1U frames for up to 6 modules and
a 1U Desktop Box for up to 2 modules. Each frame type has several front
panel variants, being, either a passive front panel, an active panel with controls
and a display or a Statesman-enabled version without controls or a display.
Apart from the Indigo DT Desktop box, all the Indigo range of frames has
plug-in PSU modules.
This manual is about the plug-in Indigo PSU modules fitted to 4U, 2U and 1U frames.
The PSU-160i is an Indigo plug-in PSU module providing a power output
of160 Watts. The PS-80i is also available as a spare 80 Watts power supply
for the Indigo 1-DP frame.
All of the Indigo PSU’s have a built-in processor, which communicates with
the front panel display processor (referred to as a PIC) such information as
power rail voltage levels (+5.75V and –6.0 V) and the PSU fan speed. The
PSU also stores its own serial number in the non-volatile memory.
As the panel processor regularly receives status updates from the PSU
processors about power rails and fan speed, the front panel is then able to
update its status LEDs and control the alarm changeover relay according to the
PSU condition. The relay contacts are available on the Remote sockets at the
rear of the frame.
A cool operating temperature is maintained by a de-mountable fan that is
positioned in front of the PSU bay, drawing air through the slotting in the front
panel.
