2. Welcome
Thank you for choosing the Black Box Central Power Hub.
In tune with your network, as KVM systems expand so
too do their requirements for the reliable supply of
power. While individual Black Box power adaptors perform well, as devices proliferate they can become
unwieldy and difficult to manage. Central Power Hub
provides the next step in terms of efficiency, reliability
and power management.
The heart of the Central Power Hub 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 20W.
The overall power is generated within the main chassis by
either one or two plug-in 460W 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.
Chapter 2: Overview
2.1 Protection and control
Power integrity, safety and management are core elements of the Central Power Hub system. The main chassis features a central
microprocessor which manages all aspects of Central Power Hub operation. At start up it checks the validity of the single (or dual)
power module(s) and then enables them. It then 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 Central Power Hub unit ensure that it fully
complies with the IEC60950-1 regulation to operate as a Limited Power Source.
The modular 460W power modules are unique; the central microprocessor circuit reads the unique code from a register in each
power module and will only enable them once the correct code is received.
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.
2.2 5VDC converter dongles
Each power output port operates at 12VDC. For devices that use 12VDC, a simple connection cable (ACR1000-3PL-CBL2M) is all
that’s required to link them to each power port. However, numerous Black Box devices operate at a lower voltage of 5VDC and
these each require the use of a converter dongle (ACR1000-12V5-CBL2M) to take the place of the simple connection cable.

• Fordevicesthatrequirea12VDCsupply,a2mlinkcable(ACR1000-3PL-CBL2M) is required.
• Fordevicesthatrequirea5VDCsupply,asmallConverterdongle(ACR1000-12V5-CBL2M)isrequiredtobepositionedcloseto
the device(s) being powered. See below for details.
• Consult the precautions listed within the Safety information section.
3.1 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 ServSwitch Agility
units 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.

3.2 Connections
The multiple output ports of the Central Power Hub each provide power at 12VDC; when
powering a 12VDC device, you merely need to use a basic cable (part number: ACR10003PL-CBL2M). However, if you need to power a 5VDC device, you must use a converter dongle (part number: ACR1000-12V5-CBL2M).
3.2.1 Connecting a 12V device
Devices that require a 12VDC supply can be connected directly to a power
port using a simple link cable.
1 Connect the locking 3-pin plug at one end of the ACR1000-3PL-CBL2M
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 Central Power Hub main
chassis.

Chapter 3: Installation
3.3 Fitting/removing a power module
The Central Power Hub 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 approved power modules may be used with the Central
Power Hub. Upon startup, each inserted power module is interrogated by the Central Power Hub and only those that
present the correct identity code will be energized. If a non-authorized power module is inserted, the INVLD indicator will illuminate and the corresponding P1 or P2 indicator (as well as the indicator on the power module itself) will
flash.
Note: Module bay 1 is on the left as you view the rear of the Central Power Hub chassis, module bay 2 is on the right.
3.3.1 To fit 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 fitting a
module to a working Central Power Hub 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.
3.3.2 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
Central Power Hub 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 section of this
guide. In particular, do not use an unearthed power socket or extension cable.
Note: Various items within the Central Power Hub 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.

As discussed in the Welcome section, the Central Power Hub ports are carefully monitored to ensure safety protection while also
maintaining power consistency to the multiple devices:
• Electronicshortprotection-Ifanoverloadorshortcircuitoccursonanyoutput,thepowerislimitedtoasafevalue(bycurrent
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 Central Power Hub 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).
• 5Voverloadprotection-ApplicableonlytooutputsthatuseoptionalConverterdongles.Whentheloadexceedsapproximately
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 Central Power Hub unit and its output will
remain intact, although the listed current output for that port will fall to (or near) zero.
5.2.1 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 Central Power Hub.
2 Depending on where the trip was made, you will see different results:
• IftheCentralPowerHubelectronicshortprotectioncircuitresponded,thefrontpanelOVLD 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 appli-
cation, the port State will be shown as FAULT.
• Iftheconverterdongleoverloadcircuitresponded,itislikelythatthecorrespondingCentralPowerHuboutputportwillstill
be active.
3 Accordingly, your remedial actions will differ:
• WherethefaultisindicatedonthefrontpanelOVLD 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.
• Wherethefaultwasdetectedbyaconverterdongle,eitherusetheStatus&Controlpageofthemanagementapplication
to switch the port Off and then On; or at the Central Power Hub 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 Central Power Hub
and all related cabling for a reoccurrence of the same or similar problem.
* 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.

Chapter 5: Operation
5.3 Resetting the Central Power Hub
If it becomes necessary to reset the entire Central Power Hub 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.
5.3 .1 Device reset from the front panel
This procedure will reset the operation of the Central Power Hub 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.
• Useanarrowimplement(e.g.straightenedpaperclip)topressandreleasetherecessedfrontpanelRESETbutton.
5.3.2 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.
