4.3 Installing the MS-SW5 into the A-100 rack
The module MS-SW5 need solely a power supply of +5 Volts, make sure that your backplane
provided well this voltage and with sufficient current.
If no, install a converter from +12 Volts to +5 Volts DC (no linear regulator, only switching
converter)
To install MS-SW5 yourself, pay attention to the following notes:
● First of all, take the A-100 rack's mains plug out of the wall socket !
● Check very carefully that the red wire of the flat cable is connected to the minus 12Volts on
the A-100 bus board.
● Failure to check this may result in the module’s instant destruction as soon as the power is
turned back on!
● The module has to be connected only to an A-100 bus board that is powered by a specified
A-100 power supply with 5 Volts rail.
● For damaged modules that have been connected obviously in the wrong way to the bus
board the warranty is void !
● Place the module carefully into the space in the rack, and fasten it firmly in place with the
supplied screws and nylon washers. Put back any covers or blanking plates, and screw them
in firmly.
● Now plug the system A-100 back into the main power supply, and switch it on.
● Test out the newly installed MS-SW5.
● If it doesn’t seem to be working as expected, immediately disconnect the system from the
power supply again. In this case, double-check the connections, making completely sure that
the ribbon cable is the right way round where it connects to the module and the bus.
