Introduction

This manual provides information covering installation and set-up procedures of the G­Converter Card Cage System.

Accommodation within the Card Cage System is provided for up to 18 Channel Cards; 1
Manager Card; and 2 Power Supplies. All cards may be ‘hot swapped’. The Card Cage
System is normally supplied with a single 40W 230V AC Power Supply Module. Additional
Power Supply Modules can be supplied to meet specific requirements.

Overview

The Card Cage System, manufactured from extruded aluminium, comprises 21 slots, within a
19-inch, 3U enclosure. A PCB back plane, which provides interconnection between the
front and rear sections of the Channel cards, is located towards the back of the enclosure.
Channel connection is achieved by simply plugging the appropriate front and rear sections
into the back plane.

TECHNICAL: 0118 931 2233

G-Converter Chassis

Manager Card

The Manager Card is a single section card that plugs into Slot 19 of the Card Cage System.
This card provides the facilities for setting up and controlling all types of Data Channel
Cards, additionally it is used to log and report faults on the Channel Cards, Power Supplies
and Cooling Fan. Both a 10 Base-T Ethernet port and an RS232 Supervisor port are
provided. Access to these ports is via the fixed rear panel of the Card Cage System.

The Manager Card is essential for controlling most types of Data Channel Cards, exceptions
being the G-Converter 2.048Mbps and the G-Converter Nx64k.

8

SALES: 0118 965 5100

G-Converter Chassis

The Nx64 Channel Cards are universal and may be operated with/or without a Manager Card.
Rotary switches, recessed into the front panel, permit selection of the data rate in [N x 64k
increments]. The selected N rate is simultaneously confirmed via the numeric display.

The 2.048Mbps Channel Cards have no set up or alarm features negating the need for the
Manager Card.

Manager Card LED Indication

On the front of the Manager Card are five LEDs. In order, from top to bottom, they are:-

LED name Function

Manager Card operational Red = faulty,

green =ok

Ethernet activity Amber = TX and RX, green = link active,

Off = no link
PSU 1 operational Red = faulty, green =ok
PSU 2 operational Red = faulty, green =ok
Fan operational Red = faulty, green =ok

Removal of Manager Card

The Manager Card can only be fitted in slot 19.

The Manager Card can be ‘hot swapped’ by simply releasing the retaining screws on the top
and bottom of the Manager Panel and with the aid of the injector/ejector handles withdraw
the card. Simply reverse this process to install the card.

N.B if the Data Channel Cards were powered during the swapping of a Manager Card then
the new Manager Card will interrogate the data channel cards for set up parameters and store
these in its non volatile memory.

Power Supplies

The Card Cage provides accommodation for up to two Euro-cassette t ypes, 40 watt, Power
Supply Modules. Typically, a single Power Supply will be fitted; adding a second Power
Supply reduces the probability of power failure.

The Power Supplies are connected to individually fused and filtered IEC inlets; each module
is capable of powering the fully populated Card Cage. If two modules are installed loading
is shared between them. In the event of one o f the modules failing the other will suppl y the
complete Power requirement of the Card Cage.

Installation

Before installation, refer to the safety warnings, approvals requirements and emc
requirements in the appendices.

Environmental Considerations

The equipment must be operated under the following atmospheric conditions:

Temperature: 0 to 40 degrees centigrade.
Humidity: 0% to 90% non-condensing.

Card Cage System

The Card Cage System should be housed in a cabinet that is considered by EN60950 to be a
suitable electrical and fire enclosure. Refer to Appendix A for safety warnings. A fixing
flange is fitted to the front of the Card Cage to mount the unit into the cabinet.

Manager Card

Note: THE MANAGER CARD MUST ONLY BE PLUGGED INTO SLOT 19.

The Manager Card is connected to the 9 Way-D Supervisor Port, and the RJ45 10Base-T
port, located adjacent to the fan on the rear of the Card Ca ge. Connection between individual
Channel Cards and the Manager Card is achieved via the back plane (See Figures 1 and 2).

There are no user configurable links on the Manager Card.

Power Supplies

The Power Supplies are installed in Slots 20 and 21. Slot 21 is located on the ex treme right
hand side of the Card Cage, when viewing it from the front, (See Figure 1). Mains power for
Slots 20 and 21 is provided by a pair of IEC connectors, the upper connector is allocated for
Slot 21, the lower connector for Slot 20.

When only one Power Supply is fitted it should be into Slot 21 with mains power being
supplied via the upper IEC connector. A blanking panel should be installed to cover Slot 20.

Channel Cards

Channel Cards for the Card Cage may be selected to meet several requirements; the cards are
fitted into slots 1 to 18. The cards can be ‘hot swapped’ by simply releasing the retaining
screws on the top and bottom of the panel and with the aid of the injector/ejector handles
carefully withdrawing the card. Simply reverse this process to install a card.

Diagnostics

For diagnostics of the Channel Cards see the relevant Data Channel Card manual.

Manager Card

The upper LED of the 5 LED display being illuminated red indicates Manager Card faults. If
the Manager is suspected to be faulty, test the functionality of the card by substitution with a
known working card.

Power Supply and Fan faults are also indicated on the Manager Card LED display,[the LED
display is shown in the diagram at the top of Page 8], in case of failure, the LED is
illuminated red.

Power Supply operation is additionally indicated by a single LED, on the front panel of the
module, this LED should be green if the Card Cage is powered.

Power Supply

The Power Supply is a 40Watt universal input (88 Vac to 264 Vac) delivering 5volts to the
back plane PCB. The Manager Card monitors the output volta ge of the Power Supplies; a
corresponding red LED on the Manager Card front panel indicates deviation outside limits.
If a Power Supply Module is suspect and the chas sis contains two Power S upplies then it can
be ‘hot swapped’ with a replacement unit. To ‘hot swap’ a Power Supply Module, release the
two retaining screws on the top and bottom of the Power Suppl y front panel and remove the
unit. Simply reverse this process to install a card. Ensure that if a Power Supply is

removed it is allowed a minute to discharge before it is plugged back into a rack system.

If the green LED on the Power Supply is not illuminated then check the fuse in the IEC
connector. If t he fuse has blo wn replace it with a “Little fuse” 5 x20mm 1.0A anti-surge. If
the PSU blows a fuse for the second time then it is faulty and should be returned for repair.

There are no user serviceable parts within the Power Supply.

Fan Assembly

This is a high reliability component and should not fail. Replacement of this component
should only be performed by a qu alified engineer. Und er no circumstances should the
fan be replaced while the chassis is powered.

SNMP Traps

When managing the unit via SNMP, it is possible to configure the chassis to send SNMP
Trap messages to a remote system when a fault condition occurs. Any fault conditions
configured to generate a minor or major alarm will also generate Traps.

Appendix C - EMC Requirements

To ensure compliance with the EMC directive, some care must be taken to ensure that the units
are installed properly, using suitable screened cables and connections. The following must be
observed:

This product relies on the use of screened cables for connection to the 9 Way 'D-Type'
Supervisor port. The cable must have the foil or braid screen connected effectively to the metal
headshell to ensure continued compliance.

The diagram below illustrates an example of a suitable screen connection. Note how the foil or
braid screen is bent back over the 'C' clip to achieve a pressure contact of the screen against the
shell:

It is important to keep the screen to shell connection as sh ort as pos sib le.
