4-68 Chapter 4: Hardware ServiceA maximum of 1A @ 5V, and 1A @ 12V can be drawn from any one ofthe three auxiliary power connectors. There is also a maximum totalcurrent that can be drawn from all of the auxiliary power connectorstogether. The 5V and 12V auxiliary power outputs can deliver 3A oftotal combined current.Example: 1A @ 5V and 2A @ 12V, or 3A @ 5V and 0A @ 12V, etc.They are specified in this manner because most peripherals draw about1A from either 5V or 12V, but not both.Auxiliary Power Board (with Cash Drawer Connector)The Auxiliary Power Board distributes power to two auxiliary powerconnectors, a printer power connector, and a cash drawer kick-out. Italso provides fuses that maintain the outputs within Class II safetylimits. These fuses are socketed and can be individually replaced.An LED is provided on the board as a servicing aid to indicate that allof the auxiliary power fuses are good (when lit). The LED is visiblefrom the back of the workstation when the cable cover is removed.
