Introduction
WELCOME
Thank you for choosing the Adder RED-PSUPRO system. In tune with your network,
as KVM systems expand so too do their requirements for the reliable supply of power.
While individual Adder power adaptors perform well, as devices proliferate they can
become unwieldy and difcult to manage. RED-PSUPRO provides the next step in terms
of efciency, reliability and power management.
The heart of the RED-PSUPRO system is a modular chassis which occupies a 1U 19”
rack slot. Arranged along its rear panel are eight or sixteen low voltage output ports.
These ports are then linked via cables and/or Converter dongles to the devices that
require power. Each output has a nominal power rating of 30W.
Protection and control
Power integrity, safety and management are core elements of the RED-PSUPRO system.
The main chassis features a central microprocessor which manages all aspects of REDPSUPRO operation. It energizes each of the power ports in a carefully coordinated
sequence to reduce the instantaneous load on the power module(s). After start up, each
power port is 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
recognizes the overload condition and trips the output – this happens approximately
one second after the fault happens. Once this occurs, you will need to correct the
source of the short circuit and then reinstate the output either via the front panel
CLEAR button or the management application. The other power output ports will
remain unaffected during this period.
• 5V overload protection - Where an optional converter dongle is used to supply a 5V
device, an extra layer of vigilance is brought into play. If the load on a dongle exceeds
approximately 5.5A, then an internal circuit will trip to protect the power modules
and the cabling. Once the cause is dealt with, a simple toggling of the power port will
restore output.
• Limited power source (LPS) - Further automated protection circuits within the REDPSUPRO unit ensure that it fully complies with the IEC62368-1 regulation to operate
as a Limited Power Source.
Available anywhere, via the in-built Ethernet port, a browser-based management
application allows authorized admin users to monitor and control the power module(s)
and all of the individual power output ports.
INSTALLATION
CONFIGURATIONOPERATION
The overall power is generated within the main chassis by either one or two plug-in
495W power modules. Adding the optional second power module provides redundancy
for mission critical installations. During normal operation, the overall load is shared
between the twin power modules, with the full load transferring instantly to one if the
mains supply to the other should fail.
5VDC converter dongles
Each power output port operates at 12VDC. For devices that use 12VDC, a simple
connection cable (VSC48) is all that’s required to link them to each power port.
However, numerous Adder devices operate at a lower voltage of 5VDC and these each
require the use of a converter dongle (PSU-RPS-5V-3M) to take the place of the simple
connection cable.
Please consider the following important points when planning the position of the REDPSUPRO unit:
• The RED-PSUPRO main chassis occupies a single 1U (19”) rack slot and requires
either one or two (when the redundancy option is used) mains inputs.
• For devices that require a 12VDC supply, a 2m link cable (VSC48) is required.
• For devices that require a 5VDC supply, small Converter dongles (PSU-RPS-5V-3M) are
required to be positioned close to the devices being powered. The converter dongle
can be up to 3m away from the RED-PSUPRO main chassis. See opposite for details.
• Consult the precautions listed within the Safety information section.
Mounting converter dongles
For each device that requires a 5VDC supply (12VDC devices require only a simple
cable), a Converter dongle is required. Each converter dongle must be placed in close
proximity to the device. To assist with mounting dongles in congested spaces, an optional
elongated rack bracket is available for AdderLink Innity units (see page 3) that allows
each dongle to be positioned just behind the device that it is powering.
Insert the tabs of the dongle
through the wider spaced holes of
the rack bracket and then slide the
dongle back to lock it in place.
Note: The indentations on the side
of the converter dongle allow it to
be xed to other surfaces using a
single plastic cable tie.

CONNECTIONS
The multiple output ports of the RED-PSUPRO each
provide power at 12VDC; when powering a 12VDC
device, you merely need to use a basic cable (part number: VSC48). However, if you need to power a
5VDC device, you must use a converter dongle (part number: PSU-RPS-5V-3M) as the link.
Connecting a 12V device
Devices that require a 12VDC supply
can be connected directly to a power
port using a simple link cable.
To connect a 12V device
1 Connect the locking 3-pin plug at
one end of the VSC48 cable to the
power input socket of the device the lead is 2m (6.5 feet) in length
2 Connect the locking 3-pin plug at
the other end of the cable to one
of the power output sockets on
the rear panel of the RED-PSUPRO
main chassis.
VSC48 link cable
PSU-RPS-5V-3M dongle
Connecting a 5V device
Devices that require a 5VDC supply require the use of a Converter dongle to form the
link between the RED-PSUPRO port and the device, while also transforming the voltage
level. Each converter dongle has two leads: a 2.5mm power jack and a locking Kycon®
3-pin plug.
To connect a 5V device
1 Mount the converter dongle close to the device that will be
powered. An optional elongated rack bracket is available to
allow the dongle to be mounted immediately behind the
device (see page 3).
2 Connect the 2.5mm power jack of the dongle to
the power input socket of the device - the
lead is 250mm (9.8”) in length.

Fitting/removing a power module
The RED-PSUPRO main chassis can accommodate two power modules, although
operation is perfectly possible with just one module tted. The addition of a second
module provides redundancy for critical installations.
IMPORTANT: To ensure correct and reliable operation, only Adder power
modules may be used with the RED-PSUPRO.
Note: Module bay 1 is on the left as you view the rear of the RED-PSUPRO chassis,
module bay 2 is on the right.
To t a power module
Note: Power modules are hot-pluggable (i.e. while
power is applied to the other module), be sure
to observe safe working practices and anti-static
precautions when tting a module to a working
RED-PSUPRO chassis.
1 If a blanking plate is tted, remove it to
reveal the power module bay.
2 Observing suitable anti-static precautions,
remove the new power module from its
packing.
3 Carefully slide the power module into the
vacant bay until the locking clip ‘clicks’ to
hold the module in place.
4 Insert an IEC power cord into the socket
on the module and apply power to the
module.
To remove a power module
Note: Power modules are hot-pluggable (i.e. while power
is applied to the other module), be sure to observe safe
working practices and anti-static precautions when
removing a module from a working RED-PSUPRO chassis.
1 Isolate power from the module to be removed and
disconnect the IEC power cord.
2 Push the locking lever to the left so that the
module un-clips and use the handle to carefully pull
the module out of the bay.
3 If no replacement module is to be used, t a
blanking plate to cover the vacant bay.

RESTORING POWER OUTPUTS
As discussed in the Welcome section, the RED-PSUPRO 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-PSUPRO
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-PSUPRO 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 rst 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-PSUPRO.
2 Depending on where the trip was made, you will see different results:
• If the RED-PSUPRO 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-PSUPRO 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-PSUPRO 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-PSUPRO and all related cabling for a reoccurrence of the
same or similar problem.
RESETTING THE RED-PSUPRO
If it becomes necessary to reset the entire RED-PSUPRO 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-PSUPRO unit, equivalent to a cold
reboot. All power outputs will be removed and then restored in a staggered manner (as
dened within the management application). No conguration details will be changed.
To reset the RED-PSUPRO 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 conguration 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 owing to the device. Roughly speaking, 5.5A at the 5V level will be
reported at the management application as 2.3A at 12V.
