Universal Serial Bus version 1.1 or 2.0 connectors Use a Universal Serial Bus (USB) connector to connect a USB device. USB version 1.1 technology transfers data at up to 12 Mb per second (Mbps) with a maximum of 127 devices and a maximum signal distance of 5 meters (16 ft) per segment. If multiple USB devices are attached to the server, the USB hub must be version 2.0; otherwise, all USB 2.0 devices will transfer data at 12 Mbps. USB devices are configured automatically, using Plug and Play technology. The following illustration shows a USB connector. 1 4 Use a 4-pin cable to connect a device to a USB connector. If you need to connect more USB devices than the server has USB connectors for, use a USB hub to connect additional devices. If you connect a PS/2 (non-USB) keyboard to the keyboard connector, USB ports and devices are disabled during POST. If you connect a USB keyboard that has a mouse port, the keyboard emulates a mouse, and you cannot disable the mouse settings in the Configuration/Setup Utility program. Video connector The integrated super video graphics array (SVGA) video controller is not removable, but you can disable it through the Configuration/Setup Utility program or by installing a PCI video adapter. Note: If you install a PCI video adapter, the BIOS will automatically disable the integrated video controller. The following illustration shows a video connector. 5 1 15 11 58 xSeries 346 Types 8840 and 1880: Hardware Maintenance Manual and Troubleshooting Guide
