Introduction
Product Overview
The 19" Rack-Mount Converters Chassis offers the
user a dedicated and secure environment for multiple
Media Conversion applications. It also allows the user
to utilize existing and new Media Converters either in
the Rack or in stand-alone installation.
Flexibility - The Chassis supports up to 12-port
card-based media converters covering 10Base-2,
10Base-T, 10Base-FL, 100Base-TX and 100Base-FX,
FDDI, ATM, Gigabit 1000Base-T, Gigabit SX / LX,
RS-232, RS-422/485 conversion. In addition, both
Multi-mode and Single-mode options are supported
too.

Reliability - The Chassis also supports two high
quality hot swappable power supplies. Either Power
unit can be removed without disturbing the Chassis’s
operation – offering total efficiency, maximum
redundancy and minimum down time. Each module is
supplied from a common shared power bus – but as
an added precaution, each is individually protected in
the event of a problem on the bus or from the power
supply. Each Converter can also be changed without
power down.
Functionality - The Chassis was carefully designed
to offer a lifetime of operation. Incorporated into the
Chassis are three long life cooling fans to ensure a
cool operating environment. Each fans is monitored
and connected to the LED Status panel. The Chassis
also features an LED Status panel. This indicates that
power is supplied to each module and that the Fans
are functioning correctly. Power supply also features a
“trigger guard” to prevent the supply from being
accidentally switched off.

Installation
This chapter will take a look at how to install
Converters into the Chassis and the different
options available for placement of the Chassis
System within its operating environment.
First, it is important to unpack the Chassis and
ensure that all the components listed on page 1-8 are
present. In some cases, the Chassis may come
complete with certain Converters already installed.
You can either install the converters first or then place
the Chassis, or you can place the Chassis and then
install the Converters. We recommend that you do the
latter as it is more convenient.
-10-
19" Rack-mount 12-port Converter Chassis
Installing the Bracket
All the Converters are made using a standard case.
This allows it to fit into the Chassis with ease. The
Converter can be mounted directly into the Chassis
without using the supplied panel but we strongly
advise against this.
We have supplied a special panel that easily
attaches to the Converter. This allows for the
secure placement of the converter into the Chassis. It
also seals off the front panel and allows the
Chassis cooling system to function correctly. The
Chassis also looks more professional this way.
-11-
19" Rack-mount 12-port Converter Chassis
Place the converter into the bracket assembly, ensuring the
power supply socket is positioned at the bottom of the
converter.
Once in place, secure the converter onto the bracket using
the two original screws you removed earlier.
-12-
19" Rack-mount 12-port Converter Chassis
Installing the Converter
Once the Converter has been attached to the bracket,
it can be installed into the Chassis. The converters
can go into the Chassis in any order and can be
placed in any available bay.
Special care must be taken to ensure the correct
mating of the power connector. Choose an available
bay and align the converter so that it fits between the
upper and lower guide rails.
Always ensure that the converter power
socket is positioned at the base of the
Chassis.
Never force the Converter into the
Chassis - check power socket position
and alignment.

If necessary, you may move the converter up & down
or left & right to meet the power connector.

19" Rack-mount 12-port Converter Chassis
Installing the Chassis
The Chassis is made from a combination of steel and
aluminum and is very sturdy in design. This allows the
Chassis to be installed in the following ways.
Rack-mount
The Chassis is built to established EIA Standards and
as such will fit into any 19” EIA designed rack. Refer
to the section “Rack-mount”
Wall-Mount
The Chassis can be mounted separately on a wall
with the use of a shelf. This should be securely
mounted on a suitable structure and must be able to
hold at least 15kg. The shelf should also be big
enough to accommodate the Chassis whilst still
offering space for adequate ventilation.

Chassis and position where suitable, again, keep
adequate space for ventilation.

Power Supplies
The Converter Chassis is normally supplied with one
redundant, hot – swappable power supply as shown
below. The design of the power system is based
around flexibility and maximum redundancy. For
normal operation, one power supply is good enough
to run fully loaded 12 converters simultaneously.
However, for critical application, to install two power
supplies are always recommended.
During 2-power operation, both power supplies will be
switched on and will share the currant load between
them. In the event that a power supply should fail, the
other supply will take 100% of the load. This will
happen instantaneously and will have no adverse
effect on the operation of the Chassis.
Similarly, if a Power Supply is removed for servicing, it
can be switched off and removed while the Chassis
continues to function as normal.

The Power Supplies can be removed from the
Chassis by simply removing the securing screws
and
ulling the supply unit out from the Chassis
Always exercise Caution when removing supplies
Always switch Power Supply off before removing
Always remove Power Cable from Supply before
removing
Do not touch Power Supply components after removal they may hold residual electrical charges

Rack Kit
The Chassis comes with a 19” Rack Mounting Kit.
This basically comprises of two brackets and a set of
bolts.
The brackets are fitted to the Chassis via six bolts.
It is strongly recommended that you use all six bolts
and use the ones supplied with the Chassis. This will
ensure that no unnecessary stress is endured by the
Chassis or the brackets.
Each bracket has EIA standard mounting holes and
are symmetrical so that either bracket can be used on
either side of the Chassis.

LEDs
To enable the operator to establish the operational
status of the Chassis, a simple LED display panel is
installed.
Its simplicity hides the fact that the Chassis employs a
sophisticated power distribution system.
All Converters are supplied from the one hotswappable Power Supply. However, this is where their
common connection stops. Each bay has its own
protection system that isolates each Converter from
any problems that might occur with either the power
supplies or another faulty Converter.
This offers the best possible protection to your
investment in the various Media Converters.

Cooling
The Chassis holds up to two Power Supplies and
twelve Media Converters, so it needs to have some
form of cooling.
This Chassis has three fans located at the rear, they
draw air into the Chassis. Each fan is connected to
the Status Monitoring Panel on the front of the
Chassis. Even with only one fan working, the Chassis
will be able to operate under normal operating
temperatures.
For the purpose of cleaning, the Fan panel assembly
can be removed for periodic maintenance. Switch the
power off to the Chassis (both power supplies!!),
remove the six securing screws and disconnect the
three power cables supplying DC to the fans.
Clean fans with a dry cloth and reverse the above
procedure.
