1. General

1.1. Introduction

The CCUR provides a local Inter-Communication point between CCU modules

within a CCU Net system. The CCUR gives customers the advantage of using

multiple types of CCU while been able to have them communicate together

using one common protocol (CCUNet).

The functionality of the CCUR is to provide power, communication and CCU

fault reporting between numerous and varied CCU’s.

This document is aimed at a technical audience so that they may be able to

understand and evaluate the operation of a CCUR.

1.2. Scope of this document

The purpose of this document is to give a simplified outline of the complete

configuration of a CCUR. The text below should provide a once off referral to be

read by a technical audience that has little knowledge of a CCUR. A clarified

description of the CCUR’s operation, including both hardware and software,

shall be combined to display the racks full integration.

1.3. Intended Audience

Incheon International Airport Korea Technical Staff, Base 2.

2. Hardware Components

The CCUR has 3 main hardware components. These being the User Interface

with LCD display, the power supply and the backplane with CCU card slots.

Each of which integrate to implement the CCUR’s functionality.

2.1CCUR Power Supply

There are two power supply configurations supported by the CCUR. The first

being a single primary supply and the second, a primary supply with a

redundant backup supply (used in the event of a primary supply failure). Each

power supply populates 3 slots in the rack and is combined with a power supply

CCU. Multiple CCUR systems utilise this CCU for communication between

racks. The diagram above shows the CCUR power supply and the appropriate

indicators.

Figure 2.1: CCUR Power Supply

Looking at the left side of each power supply face plate there is an ON/OFF

switch (I/O) and an external power source input. The ON/OFF switch controls

flow of power from the external power source to the backplane. It is possible to

have the switch OFF and the board still running if a secondary CCUR/PSU

board is installed. On the right, from the top, there is a relay for failure

annunciation. Below the relay are the CCUpower supply LED indicators and

under the LED’s is the CCU power supply communication port. The Power

Supply Communication Port is standard DCE RS232 communication. See

Appendix A for pin wiring.

ATTN: The external power supply cable must be plugged into the connector

and the rack power switch must be turned off before powering on the external

power supply.

2.2CCUR Backplane and Slots

The CCU Rack consists of 21 slots. Depending on the configuration of the rack

slots 4-21 will have a custom configuration. Slots 1, 2 and 3 will always be the

same. The CCU primary power supply will reside in slot 1, the CCU/LCD card

will be in slot 2 and slot 3 will be empty. Therefore with a single power supply up

to 18 additional CCU cards can be fitted in the rack.

Shown below is a demonstration implementation. It can be seen that this is a 2

power supply configuration (primary and redundant supplies, slots 1-3 and slots

19-21). A bank of CCUR/422 cards sit next to the primary power supply and are

used for external communication with 8 devices. A CCUR/232 card resides in

slot 18 and provides RS232 communication with another external device. Each

of these cards connect to the backplane and use CCUNet protocol for

intercommunication. Hence providing 18 separate connections to the CCUNet.

2.5CCUR LCD

The CCUR/LCD board’s primary objective is to supervise the CCUR cards in the

rack and to provide visual and audible annunciation if any are in fault.

Below is a diagram of the CCUR/LCD board. Descriptions of the ports are shown

as well as the jumper pins.

Figure 2.5: CCUR/LCD board

2.5.1 Reprogramming Port

The reprogramming port has the 3 CPU settings on the top 3 pairs of jumpers.

R is the RESET jumper, A is MOD A and B is MOD B jumper. The remaining 6

pins are the port connections to the reprogramming PC’s COM port (RS232).

ATTN: The reprogramming port must only be used by a qualified service

engineer with appropriate training and experience.

2.5.2 LED Port, Keyswitch Port and KeyPad Port

Each of these ports have bus cables connected to them which come from the

CCUR LCD face plate.

2.5.3 CCU Rack Address Jumper

The 3 jumpers, numbered 1-3, are the jumper selectable addresses of the CCU

rack the CCUR LCD board is plugged into. CCUR addresses can be specified

from 0 to 7 and must be the same for every card on the rack. The following

diagram shows the jumper selection for the appropriate addressing.

Figure 2.2.3: CCUR Fibre HUB address jumper settings

These jumpers set the 3 high address bits of the CCU address (8 bits long).

The remaining 5 bits are determined by the slot number the card is plugged into.

NOTE: Each of the cards in the rack must have the same rack address

jumper settings. If the address of the rack is to be changed then the rack should

be powered OFF before changing each of the address jumpers on the CCUR

cards.

DO NOT ALLOCATE OTHER CCU NODE ADDRESSES WITHIN THE 1-

32 ADDRESS RANGE (ie. lower 5 bits) SELECTED BY THE RACK

ADDRESS.

2.5.4 Volume Control

Using a philips(star) head screw driver the loudness of the fault buzzer can be

adjusted to suit your needs. The total rotation of the screw is only 360oso

please rotate the screw slowly.

2.3User Interface with LCD Display

The front of each rack has a keyswitch, a LCD display and various buttons. While

the keyswitch is in the LOCK (OFF) position the rack will not respond to any button

being pressed and will show limited system information on the LCD.

2.3.2 Error messages and Fault Procedures

There is one fault “error message” that is displayed on the CCUR LCD display

1. CARD NOT PRESENT OR FAULTY

Figure 2.3.2: CCUR LCD Display

1. CARD NOT PRESENT OR FAULTY

This error message is displayed if a slot that would normally be occupied is

not plugged in properly or the card is faulty. The latter meaning there is no

communication to or from that card –probable cause a chip has blown or the

firmware has encountered an erroneous state.

To rectify this problem, firstly try pushing the card in again so that it is

secure and will clip in. If this does not clear the message then the card should

be replaced immediately and the faulty card should be checked and fixed by a

service engineer.

2.4Adding and Removing CCUR Cards

In the event of a CCUR card becoming faulty it will need to be replaced. To

complete the replacement there are 4 steps to follow.

NOTE: Although all cards in the CCU Rack are "hot swappable", some require a

specific procedure to remove them. The CCUR/PSU, for instance, must have it's

ON/OFF switch in the OFF position and the external power for that card must be

powered down before card removal. If unsure check the specific manual for the

CCUR card.

1. Check and ensure you have correctly identified the card that is faulty. This

should have been done by inspecting the CCUR’s LCD for the slot number and the

card’s name.

2. Unplug the cable(s) from the CCU PORT(s).

3. Unscrew Top most and Bottom most screws. The top one will be a philips (or star)

screw and the bottom one will be a blade (or flat) screw.

4. Use the black clip above the card to pop the card out. Quickly and firmly raise the

top clip. Carefully slide the card out.

5. Slide the replacement card in until it has 1 centimetre left to go. Then

confidently push the card in the rest of the way until the top black clip has

locked the card into place.

6. Screw in the Top most and Bottom most screws.

7. Reconnect the cable(s) to the card.

If successful, the fault message will disappear from the CCUR LCD.
