3.4.3
Power Supply Units (Mod. A1532)
The Power Supply Units (Model A1532) deliver voltage (+48 V, 750 W) for the system
boards supply. The SY1527 mainframe can house up to three A1532 units allowing to
reach a 2250 W maximum output power.
Any configuration of the SY1527 system includes at least one A1532 unit for the power
supply of the board section.
Each of the A1532 Power Supply Units can be placed in any of the housings from #1 to
#3 on the mainframe’s front part , i.e. any housing except for the first housing on the right
(Housing #0) which is reserved to the Primary Power Supply (refer to Fig. 3.1, p.19).
Both the Primary Power Supply and the Power Supply Units have bias pins to be
inserted into the relevant mating holes of the backplane. In order to avoid a
misplacement of the Primary Power Supply, the latter has a bias pin placed in a different
