1 KBU 64 Rackmount Specification
1.1 Introduction
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.

KBU 64 Rackmount Specification
80-10100001-09 1–3
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 80-
10100000) 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.

description of operation.
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.

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
80-10100001-09 3–3
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.
3.3 Rear 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.

KBU64 RackmountUser Manual

20 108 Data Terminal Ready
These command ports are PSV4/1 compatible and can therefore be
connected to external port sharing devices (PSV’s) for management of
multiple racks of KBU 64s in the same way as the standalone version.

Card Installation
80-10100001-09 4–1
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.

80-10100001-094–2
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.
