19" Rack-mount 12-port Converter Chassis
1 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.

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.

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.

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.

Desktop

The Chassis can be situated on any suitable desk top. Simply attach the adhesive feet to the base of the Chassis and position where suitable, again, keep adequate space for ventilation.

3 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

4 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.

5 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.

Fan Indicator LED’s

These should be illuminated under normal operating conditions

Bay Power LED’s

These will illuminate when a Converter is supplied to the Converter.
LEDs will be extinguished if a Converter is not installed or there is a problem with the power.

6 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.
