7546 Parts List
191-151  IBM 7546 INDUSTRIAL COMPUTER (-011)
192-298  IBM 7546 INDUSTRIAL COMPUTER (-A11,411)

Power
197 W, used in the 8577/9577 Dual voltage with manual switch

205W, 84F7405 (SWAG)-  Auto-ranging (no switch)
15F8625, Battery (for 205 w power supply) 
04G2162, Tray, Battery

When the 205W power supply is installed in the 7546 with the optional backup battery in place, the maximum number of DASD devices that can be installed internally is reduced to three.  This is because the battery is
located in a bay that could otherwise accept a DASD device.
