Getting Started2.2 Connecting powerThe Integrator/CP can be powered from the external Power Supply Unit (PSU)packaged with the system or from an alternative external D.C. supply. Figure 2-2 showsthe power supply connectors.Power buttonJ39V to 20V D.C.+GNDFuse(T2.5A)5V OK3V3 OKStandbyJ412V 35W PSU(packaged with system)External power buttonconnector(J5)Figure 2-2 Powering the assembled Integrator/CP systemConnect either:• the PSU packaged with your system to J4 on the baseboard. The PSU is capableof supplying 12V at 2.92A from an A.C. supply of between 100V and 240V. (Thisis the preferred supply.)• an external supply, between 9V and 20V D.C., to connector J3.Onboard voltage regulators provide 3.3V and 5V. The on-board regulators can supplythe maximum currents shown in Table 2-2 on page 2-5 from a 9V to 20V input. Thisinput is protected by a 2.5A time-delayed fuse and shuts down if the supply voltage dipsbelow 9V. On some models, the fuse is in a different location, but it is easily recognized.When you apply power to J3 or J4, the standby LED illuminates. To power the systemup, press the power button (S1).CautionDo not connect power to the power connector on the core module.2-4 Copyright © 2002 ARM Limited. All rights reserved. ARM DUI 0159B
