•  Name - the primary identity of this RED-PSU unit.
•  Description - a further opportunity to add more information about 
the RED-PSU unit. 
•  Location - a useful feature if you have multiple RED-PSU units 
distributed around.
•  Login required - when ticked, all users will be requested to enter a 
valid username and password prior to access being granted.
•  Start up delay - this setting determines the time delay in seconds that 
should elapse, after mains power is first applied to the unit, before 
the power modules apply their full supply to the RED-PSU chassis. 
This feature is useful when multiple RED-PSU units are fed from the 
same mains power feed. By staggering the switch on points of the 
various units, the impact of multiple switched mode power supplies 
and their initial in-rush currents are greatly reduced. Values range 
from 0 to 10 seconds.
•  Channel interval - this setting determines the time delay, in seconds, 
that should elapse between each power output port being energized. 
This performs an important task in preventing initial power overloads 
as each device reaches its quiescent state. Values range from 0.1 to 2 
seconds. 
•  Firmware version - displays the current version of internal software 
used within the RED-PSU logic system. 
•  Identity - used to visually identify the RED-PSU unit when multiple 
units are installed together. Click the Flash LED button to flash the 
front panel LED indicators, as follows:
•  Click the button once to flash the LED indicators five times.
•  Click the button twice to flash the LED indicators indefinitely.
•  Click the button a third time to stop the flashing.

The RED-PSU main chassis contains various indicators to provide you with status 
information. There are four main indicators on the front panel as well as green and 
amber indicators on the network port connector.
Red status indicators
The red status indicators on the front panel provide various key power and operation 
feedback:
P1
On:  The power 
module in bay 1 has 
a mains input and is 
operating.
Flashing:  An invalid 
power module has 
been inserted into 
bay 1. inVlD
Flashing:  One (or 
both) of the power 
modules is an invalid 
type.
o
VlD

ReStoRinG Po
WeR outPutS
As discussed in the Welcome section, the RED-PSU ports are carefully monitored to 
ensure safety protection while also maintaining power consistency to the multiple 
devices:
•  Electronic short protection - If an overload or short circuit occurs on any output, 
the power is limited to a safe value (by current pulsing) until the microprocessor 
recognises the overload condition and trips the output – this happens approximately 
one second after the fault happens. The resulting trip is indicated on the RED-PSU 
front panel by the OVLD being on and also within the management application 
(‘FAULT’ is shown next to the affected port within the Status & Control page ) . 
•  5V overload protection - Applicable only to outputs that use optional Converter 
dongles. When the load exceeds approximately 5.5A*, a dongle will internally trip its 
power output. In most cases this will occur before the electronic short protection 
(mentioned above) reacts. In such cases, the power trip will not be reported back to 
the RED-PSU unit and its output will remain intact, although the listed current output 
for that port will fall to (or near) zero.   
to restore a power output
1  Following an automatic power trip, your first task is to locate the cause of the 
problem. It may have been a temporary overload issue that has subsided or something 
more permanent. Perform thorough checks on the implicated device and all of the 
power cabling between it and the RED-PSU.  
2  Depending on where the trip was made, you will see different results:
•  If the RED-PSU electronic short protection circuit responded, the front panel 
OVLD indicator will be lit and also the rear panel green indicator adjacent to 
the affected port will be OFF . Within  the Status & Control page  of the manager 
application, the port State will be shown as FAULT.
•  If the converter dongle overload circuit responded, it is likely that the 
corresponding RED-PSU output port will still be active. 
3  Accordingly, your remedial actions will differ:
•  Where the fault is indicated on the front panel  OVLD indicator (once you have 
diagnosed and corrected the cause), use a narrow implement (e.g. straightened 
paperclip) to press and release the recessed front panel CLEAR button.  The power 
output to port will be reinstated. Alternatively, within the management application 
(Status & Control page ), click the FAULT state shown against the affected port. 
•  Where the fault was detected by a converter dongle, either use the  Status & 
Control page  of the management application to switch the port Off and then 
On; or at the RED-PSU rear panel remove and reconnect the converter dongle 
connection.  
4  For a suitable period after resuming the power supply to the affected port, closely 
monitor the device, the RED-PSU and all related cabling for a reoccurrence of the 
same or similar problem. 
ReSettinG the  ReD-PSu
If it becomes necessary to reset the entire RED-PSU unit, this can be achieved either 
using the management application (see  The Systems operation page) or the recessed 
RESET button on the front panel. Using either method it is possible to enact a basic reset 
(equivalent to removing and restoring mains power) or a full factory reset.
Device  reset from the front panel
This procedure will reset the operation of the RED-PSU unit, equivalent to a cold reboot. 
All power outputs will be removed and then restored in a staggered manner (as defined 
within the management application). No configuration details will be changed.
to reset the ReD-PSu device
1  Use a narrow implement (e.g. straightened paperclip) to press and release the 
recessed front panel RESET button.
Factory reset from the front panel
This procedure will perform a cold reboot but will also return all configuration details 
to their factory settings. Note: The IP address will be returned to 192.168.1.22 (DHCP will be 
disabled) and all user entries apart from the main admin will be removed. 
to perform a factory reset
1  Use a narrow implement (e.g. straightened paperclip) to press and hold the recessed 
front panel RESET button for 20 seconds.
  
* If you are using the management application to monitor supply currents, remember that due 
to the conversion from 12VDC to 5VDC, the values shown at the power output ports (within the 
app) differ from the currents flowing to the device. Roughly speaking, 5.5A at the 5V level will be 
reported at the management application as 2.3A at 12V.
