ADDER RED-PSUPRO 19-Inch Rack Mountable Power Distribution Unit User Guide

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 difficult to manage. RED-PSUPRO provides the next step in terms of efficiency, 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.

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.

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.

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) to take the place of the simple connection cable.

Installation

LOCATION
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) 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 Adder Link Infinity 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 fixed 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) as the link. Connect the converter dongle 2.5mm jack to the power input of the device.

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.

To disconnect a 3-pin locking plug

1. Use the management application to remove power from the required power outlet – the green indicator must be off.
2. Grasp the outer body of the 3-pin plug.
3. Gently pull back the body of the outer plug. As the body of the plug slides back, it will release from the socket and you can fully withdraw the whole plug.

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.

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.
   

3. Connect the locking 3-pin plug to one of the power output sockets on the rear panel of the RED-PSUPRO main chassis – the lead is 3m (10 feet) 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 fitted. 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 fit a power module
Note: Power modules are hot-pluggable (i.e. while power is applied to the other module), be sureto observe safe working practices and anti-static precautions when fitting a module to a working RED-PSUPRO chassis.

1. If a blanking plate is fitted, 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, fit a blanking plate to cover the vacant bay.

IMPORTANT: Please read and adhere to the electrical safety information given within the Safety information leaflet. In particular, do not use an unearthed power socket or extension cable. Note: Various items within the RED- PSUPRO casing generate heat when in operation and will become warm to the touch. Ensure that air can circulate freely at the rear of the enclose, particularly by the power module cooling fans. Do not operate the equipment in ambient temperatures exceeding 50 degrees Centigrade. Do not place the products in contact with equipment whose surface temperature exceeds 50 degrees Centigrade.

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 recognizes 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 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-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 defined within the management application). No configuration 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 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.
