KBU 64 Rackmount Specification

1KBU 64 Rackmount Specification

1.1Introduction

This manual describes the Rackmount version of the KBU64. The standalone KBU 64 has its own manual, Publication 80-10100000. For information on the command menus and parameters in the rackmount version, you will need to refer to the standalone KBU 64 manual.

The rackmount KBU 64 is a dual channel rack mountable card that uses the KBU 64 Card Frame as a host for power and management via the Management Card. The rackmounted KBU 64 consists of a KBU card and a rear interface card (card 'pair'), both cards connecting to a motherplane for power source and management. Rear interface cards may be ordered as X.21, V.24, or V.35 variants.

Power supply is via two switching supplies, which normally load share when both are fitted.

Figure 1.1 The KBU 64 Rackmount Version

Up to 13 KBU 64 card pairs may be fitted with either one or two power supplies for resilience. The 1st card slot is for the Manager Card which controls all cards within the rack via the KBU 64 polled management system. If the Manager Card is not fitted, management of each card can be performed by connecting a terminal directly to the command port of the rear interface card. When fitted, the manager card must be placed in slot 1, the left-hand most slot of the rack.

1–2	80-10100001-09

KBU 64 Rackmount Specification

The rackmount version of the KBU 64 is functionally the same as the standalone in most respects, as it uses the same software. Therefore most of the sections of your KBU64 Manual manual (Publication 8010100000) relating to KBU 64's operation are relevant.

The rackmount card functionality differs in the following ways:-

∙There is a single 15 way command port on each KBU 64 rear card for all commands and alarms. There is no separate alarm port or alarm relay output on the cards. The command port has the same function as the standalone 25 way command port.

∙The Management Card (if fitted) provides a command port for access to all KBU 64 cards in the rack.

∙Standard physical interfaces are provided for X21 (15 way 'D'), V35 (34 way MRAC), and V24 (25 way 'D'). This means that the V11/V28 selection links are not provided as they are no longer necessary. A choice of 3 rear interface cards exist to provide these interfaces.

∙The interface LED's are as for the standalone except that the Link LED's have been omitted for front panel clarity.

∙The ISDN cable is connected to the Rear Interface Card by an RJ 45 style plug.

∙Power indication for each power supply is present on the Manager Card.

2.2 Rear Interface Cards

With all 3 card types the USER ports are configured as physical DCEs, the LINK ports as DTEs. The USER ports are female and the LINK are male for X21 and V24, both USER and LINK ports are female for V35.

All three card types use standard pin connection and so require 1 to 1 cables for connection to both user equipment and link equipment.

Manager Card

3 Manager Card

3.1 Introduction

The KBU 64 Manager Card is a discrete card for use with only rackmount KBU 64 cards. Like the rackmount KBU 64, the Manager Card also consists of a card pair. The rear card provides a command port for management of all KBU 64 cards within its rack.

The Manager Card must always be fitted in slot 1, the slot on the left when viewing the rack from the front.

Important

When the manager Card is used you cannot use the command port of any KBU 64 Rear Interface Card. With the Manager Card fitted you must remove links 12, 13 and 14 on every KBU 64 Rear Interface Card to disconnect the card command interface. If you do not do this the signal flow to the Manager Card will be corrupted.

Manager Card

3.2 Front Panel

The front panel of the Manager Card has the following controls and indicators:

∙Transmit and receive data LED’s for the command terminal data lines. These LED’s display data activity on both the transmit and receive data circuits.

∙AC power indication for each of the power supplies. These LED’s are fed from the AC power sensing circuits from each power supply.

∙A lock out switch for each of the 13 channels. These are provided to enable the user to set the poll number for individual KBU 64 cards. Once the cards have been programmed ALL the lockout switches must be set to enable the KBU 64s. The lockout switches can also be used to isolate a KBU card that is streaming unwanted alarms, so allowing other KBU cards to have access from the Manager Card.

∙An LED for each channel to indicate which channel is actively selected and in communication with the Manager Card. When another KBU 64 card is polled that card's LED will light and the previously selected card LED will extinguish.

3.3Rear Panel

The command port on Manager Rear Interface Card is a female 25 way 'D' type and uses the same V28 level circuits and pin connections as the standalone KBU 64.

Card Installation

4 Card Installation

Each KBU 64 ‘front’ card must be associated with an appropriate (V.24, X.21, or V.35) rear interface card i.e. they should always be installed in pairs (although no damage will result in partial installation)

If the KBU 64s are to be managed individually via their rear panel command port and there is no manager card present then, after connection of the user, link, and command cables, the KBU 64s can be treated in the same manner as standalone KBU 64s for configuration purposes.

When installing KBU cards in a rack make sure to configure the Rear Interface Card straps correctly, depending on whether a Manager Card is fitted. Refer to KBU64 Manual (Publication 80-10100000) - Link Settings.

4.1 Manager Card Installation

When the KBU 64s are to be managed with a KBU 64 rack manager card then the manager card must be placed in slot 1, the slot on the far left when viewing the rack from the front.

If the Manager command port is conected direct to a terminal/PC then cable CAB0017 or CAB0018 is required (CAB0017 has a female connector and CAB0018 a male connector at the terminal end). If connected to a PSV port sharer please contact your Technical Support for details.

With a directly connected terminal it may be necessary to force CTS or DCD to the terminal, depending on the terminal’s requirements.

KBU64 Rackmount User Manual

4.2 Configuration Using a Manager Card

With the Manager Card pair and all KBU card pairs fitted the first task is to set the individual KBU 64 poll numbers. Once all the units are installed and a suitable terminal connected to the rack manager card command port, the lockout switches should be set to disable access to all the KBU 64s except one (for the sake of convenience it is better to configure the left most KBU 64 first). The individual poll address can then be set by typing the following commands:-

1> SET POLL xxx[CR]

where	xxx	represents the unique address in the range 001 to
999

Next, the KBU 64 card needs to be set for polled mode by typing

1> SET CONSOLE POLL[CR]

To check that the KBU 64 is responding, type

1> POLL xxx [CR]

where

xxx

represents the address that you have just set

The lockout switch for this KBU 64 should then be set to disable the KBU 64 and the next KBU 64 can be programmed by enabling via the lockout switches etc. etc.

Once all the KBU 64s have been programmed, the lockout switches must be set to enable ALL the KBU 64s.
