Crystal Vision Introduction
Indigo PSU Manual R1.1 2 16/06/2010
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 Indigo range of plug-in PSU module are available in power outputs of, 75 watt (PSU-
75i), 150 watt (PSU-150i), 160 watt (PSU-160i) and dual 55 watt for the Indigo 1-DP
(PS-55i). The 150-watt PSU is also available with 48Vdc input, (PSU150i-48V).
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.
In general, the 75-watt PSU-75i was used in the 1U Indigo 1 frames and the 150-watt
PSU-150i is used in both of the larger 2U and 4U frames. The recently introduced PSU-
160i will in time supersede both the PSU-75i and PSU-150i. The dual PS-55i power
supply modules can only be fitted into specially modified Indigo 1-DP frame.

Indigo 1-DP power supply module
The Indigo 1-DP is fitted with a pair of removable slim-line 55-watt power modules.
These modules fit side by side in the place of the single PSU module in an adapted Indigo
1 frame.
Note: The maximum power is limited to 55 Watts. Ensure this maximum is not exceeded by
the inappropriate selection of cards fitted into the frame.
Left/Right conversion
For a pair of PS-55i power supply modules to fit side-by-side in the 1U power supply bay
it is necessary for them to be handed i.e. a power supply module set for the right hand
position will not fit into the left-hand and visa versa. Reconfiguring a PS-55i to its
opposite handing requires the power supply module to be repositioned on its carrier-
board. The removal of two fixing screws will allow this repositioning of the module.

Dual power supplies mother-board.
The PS-55i power supply modules are mounted into the Indigo 1-DP frame by way of a
retained mother-board. This mother-board which remains in situ contains the CPU, alarm
relay and low voltage fusing for the frame bays. It is also the purpose of the mother board
to connect the two PS-55i power supplies to the frame and supply the mains input
connection. There are no user adjustments on this board so removal should not normally
be necessary.
Dual PSU mother-board assembly

Crystal Vision Installation
Indigo PSU Manual R1.1 7 16/06/2010
The dual power supply mother-board is retained by a pin at the front end of the central
runner. This pin is press fitted into a hole in the chassis. To remove the mother-board lift
the front of the runner to disengage the pin and pull forward to unplug and remove.
Refit in reverse ensuring that the pin is fully located into the chassis hole.
Mains Combiner
In situations where power redundancy is required in the Indigo 4 a third PSU module is
added. For this third PSU to function in the event of one of the two mains inputs failing,
the PSU-CMB or PSU-CMB2 mains combiner is fitted to the vacant slot in the upper
PSU bay. The mains combiner has been designed to be narrower than a PSU module so
preventing either the mains combiner or PSU module from being inter-changed. The
mains combiner has a pair of alarm relay contacts which will close on the loss of a mains
supply or internal fault. These contacts are available from the Remote connectors on the
rear of the frame. See power supply relay connections for details.
Note: The PSU-CMB is used with the Indigo 4 frame when fitted with a PSU-150i third
supply. The PSU-CMB2 is used with a PSU-160i third supply. PSU-CMB and PSU-
CMB2 are note interchangable.

Configuring Indigo 2 PSUs
The 2U Indigo 2 frame will take either one or two PSU modules. If one PSU module is
fitted, either the upper or lower slot in the PSU bay may be used. If one or two power
supply modules are fitted the frame must be configured accordingly. The position of the
two-position slide switch on the top right of the front panel PCB must be set to one or
two.
Indigo 2/2A/2S front panel hardware settings – PSU configuration
If both power supplies are fitted the slide switch is set to position two. If the switch is set
to one and there are two power supplies fitted, the LOWER PSU LED will flash from
GREEN to OFF every 2-3 seconds to warn that the switch is set to one instead of two.
Warning: These servicing instructions are for use by qualified personnel only. To reduce risk
of electric shock, do not perform any servicing other than that contained in the
Operating Instructions unless you are qualified to do so. Refer all servicing to
qualified service personnel.
Refer also to the General Safely Summary in the Installation chapter.
Configuring Indigo 4 PSUs
The 4U Indigo 4 frame will take either two or three PSU modules. The PSU modules are
to be fitted in both the lower and the uppermost slot positions. The two vacant slot
positions are for the Mains Combiner module upper and third PSU module lower.
Note: The third PSU module relies on the presence of the Main Combiner module for its
operation. If two or three PSU modules are fitted again the frame must be configured
accordingly. The position of the two-position slide switch on the top right of the lower
front panel PCB must be set to one for two PSUs or two for three PSUs and Mains
combiner.
If the PSU configuration switch is set incorrectly the lower front panel PSU status LED
will flash as a warning.

Inserting and removing power supplies
In multi-supply frames one of the power supplies at a time 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 or handles 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-75i – 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.
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 two/one switch behind the control panel is set correctly for the number of
PSUs installed to prevent redundant PSU warnings.

Crystal Vision Installation
Indigo PSU Manual R1.1 10 16/06/2010
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 PSU extractor
handle fully outwards to clear the panel hinge
Carefully push the PSU all the way into its socket
Note: 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 two/one switch behind the control panel is set correctly for the number of
PSUs installed to prevent redundant PSU warnings.
Refitting 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 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
If the frame is powered, the PSU fan should now be operating and the PSU FAN LED
should be green.

Power supply related faults operate a relay the contacts of which are brought out to the
Remote connectors. These contacts can be used to operate external indicators as desired.
Please refer to the power supply pinout section for more details.
The PSU-150i-48V line fuse is located internally to the PSU module. Replacing this fuse
will involve dismantling the module. See replacing PSU-150i-48V fuse
Note: The red LED built into the front of the vertical PCB on the LHS of the PSU will flash
repeatedly (on for one second and off for one second) if there is no speed fan signal
present on the connector SK1( the front LHS of the PSU). This will occur when the PSU
Fan assembly is removed or if the PSU fan stops. When the fan speed signal is present
the LED is unlit. The same red led will light up continuously if levels of the power rails
(+5.75V or –6.0V) are outside operational limits. Refer to Section 2.6 for further details.
Replacing the mains input fuses
The mains input fuses are fitted inside the IEC 320 connectors at the rear of the frame. A
spare fuse is also stored inside the connector. The fuse can only be accessed when the
power cord is disconnected.
The sequence is as follows: -
Disconnect ALL the power cords (one or two depending on configuration) from
the rear of the frame.
Using a flat bladed screwdriver or similar tool gently lever out the fuse drawer
from the relevant IEC connector using the tab visible at the bottom of the
connector depression
Remove the defective fuse and replace with either the spare fuse or with a 5A,
250V time delay fuse
Replace the fuse drawer and reconnect the power cords

and spare fuses
If a fuse blows repeatedly this indicates a fault either in the associated power supply
module or elsewhere. Return the frame and/or power supply to the manufacturer or dealer
for repair.
Note: Replace the fuse only with one of the same type and rating (5A, 250V time delay).
Replacing the PSU-150i-48V fuse
The supply input fuse is fitted inside the PSU150I-48Vdc module. The fuse can only be
accessed once the PSU module has been removed from the frame.
The sequence for replacing the fuse is as follows: -
Remove the un-powered PSU module from the frame.
Using a pozi headed cross-bladed screwdriver remove the six screws securing
the transparent insulation cover from the under side of the PSU.
Remove the four further screws one from each corner of the dc-dc module and
prise its rear edge from the carrier board. The DC-DC module will then swing
out still attached by its input wiring loom. This loom maybe disconnected to
allow the complete removal of the module or it is possible to replace the fuse
whilst still attached.
Note: As a precaution the screw retaining the CPU module may be removed to prevent
excessive strain being put on it.
Remove the defective fuse and replace with either the spare fuse or with a 10A,
250V time delay fuse.
A spare fuse is stored in a clip which is attached to the PSU module and can be
accessed once the module is removed.
Reassemble in reverse order.

If a fuse blows repeatedly this indicates a fault either in the associated power supply
module or elsewhere. Return the frame and/or power supply to the manufacturer or dealer
for repair.
Note: Replace the fuse only with one of the same type and rating (10A, 250V time delay).
Indigo 1-DP
The Indigo 1-DP does not have externally accessible mains fuses. They are situated on the
Power supply modules. To service these fuses it is necessary to remove the power supply
module from the frame.
PS-55i showing mains fuse.
To replace the mains fuse first remove the protective cover. The fuse may then be prized
from its carrier with the aid of an instrument such as a flat bladed screwdriver. Take care
not to damage any surrounding components or wiring. Once the replacement fuse has
been inserted ensure the safety cover is replaced before refitting the module.
Note: Replace the fuse only with one of the same type and rating (5A, 250V time delay).
