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.
