The main difference with the Australian panels is that they are assembled in the
Australian (Tyco) range of rack cabinets.
Some further specific differences follow:
• Only the Expansion Bay is used, with the Controller CPU and Motherboard mounted
in the right hand side of the first one. The standard US Controller Bay is not used.
• The Operator Interface is fitted to an Australian specific 4U hinged bracket mounted
above the first bay.
• Australian specific bay mounting brackets and trims are used. This includes the
standard range of 19” rack mount panels and brackets.
• Only one version of SPS is available. This mounts on a specific bracket and also to an
expansion bay, and is unique to Australia.
• Only one version of IDNet card is used, ie the 4100-3101.
• Two of the addressable modules were modified specifically for AS4428, i.e. 4090-
9117AU Addressable Power Isolations, and the 4090-9120AU 6 Point I/O.
• Other cards / modules not used in Australia include the large range of Evacuation
products and some modems.
Standard 4100 motherboards and cards fit in a 4100U bay. The following items however,
do not fit:
• 4100 Switch/LED display modules;
• The range of Australian brackets that mount to the front of a 4100 bay. This includes
some EWIS products, Brigade interface brackets, T-Gen bracket, and printer.
• The metal bracket that mounts into a 4100 bay (as does a Motherboard), and houses:
the 25W and 50W amplifiers; the T-Gen; two MiniGens; the 1948 24V 2A PSU; or
the Powerblock PSU.
A revised version of this bracket has been designed to mount the T-Gen, two
MiniGens or the 1948 PSU into a 4100U bay. It does not, however, take the two
amplifiers. The Powerblock. PSU is not available in this form.
Note that although 4100 cards fitted to motherboards, and the bay mounting brackets, can
be fitted in directly behind Switch/LED modules, they cannot be fitted behind the 64/64
Switch/LED Controller mounted to the inside of the bay door. This is typically mounted
behind the LED/Switch Modules fitted to the 3
rd
and 4
th
positions from the left.
