6-pin IEEE 1394 (FireWire) connector (rear) 24 6 13 5 Keyboard connector There is one keyboard connector on the rear of the computer. Use this connector to connect a PS/2 (non-USB) keyboard. The following illustration shows a keyboard connector. 6 5 4 3 2 1 If you attach a keyboard to this connector, Universal Serial Bus (USB) ports and devices are disabled during the power-on self-test (POST). Parallel connector There is one parallel connector on the rear of the computer. Use this connector to connect a parallel device. The following illustration shows a parallel connector. 13 1 25 14 The parallel connector supports two standard IEEE 1284 modes of operation: enhanced parallel port (EPP) and extended capability port (ECP). If you configure the parallel port to operate in bidirectional mode, it supports the ECP and EPP modes. When the parallel connector is configured as bidirectional, use an IEEE 1284-compliant cable that does not exceed 3 meters (9.8 ft). Use the Devices and I/O Ports options in the IBM Configuration/Setup Utility program to configure the parallel connector as bidirectional. Serial connectors There are two serial connectors on the rear of the computer. Use these connectors to connect serial devices. The following illustration shows a serial connector. 1 5 6 9 Universal Serial Bus connectors There are eight USB 2.0 connectors, two on the front and six on the rear of the computer. Use the USB connectors to connect optional telephony and multimedia devices. USB 2.0 technology transfers data at up to 480 Mbps (megabits per second) with a maximum of 127 external devices and a maximum signal distance of 5 meters (16 ft) per segment (if the device that is attached to the computer is a USB 2.0 device). If multiple USB devices are attached to the computer, the USB hub must be USB 2.0; otherwise, all USB 2.0 devices will transfer data at 12 Mbps. 60 IBM IntelliStation M Pro Type 9229: User's Guide
