Sleep/Resume

This two pin header, when connected to a momentary switch, can be used to put the system into a power managed state (standby) that will reduce the system’s power consumption. If the system is in Stand By mode and the switch is pressed, the system will instantly “wake up” or Resume full system activity. When used with a power supply with a high efficiency rating, the Advanced/ZE is easily capable of reducing the system power to below EPA Energy Star requirements. The function of the Sleep/Resume button can also be achieved via the keyboard with a hot key sequence programmable in setup.

Infra-Red (IrDA) connector

Serial port 2 can be configured to support an IrDA module via a 5 pin header connector. Once configured for IrDA, the user can transfer files to/from portable devices such as laptops, PDA’s and printers using application software such as LapLink. The IrDA specification provides for data transfers at up to 115kbps from a distance of 1 meter.

Speaker

The external speaker provides error beep code information during the Power-On Self Test if the system cannot use the video interface. See the appendix for more information about error beep codes.

BACK PANEL CONNECTIONS

The back panel provides external access to an AT style keyboard connector integrated on the Advanced/ZP baseboard. Figure 4 shows the general location of the AT style keyboard connector.
