might need to upgrade the operating system to support SMP. For more information, see IBM BladeCenter HS40 Type 8839 Installation and User's Guide and Eserver your operating-system documentation. Input/output connectors and devices The input/output connectors that are available to your blade server are supplied by the BladeCenter unit. See the documentation that comes with your BladeCenter unit for information about the input/output connectors. The blade server has two selection buttons on the control panel: the CD/diskette/USB select button and the keyboard/mouse/video select button. See "Controls and LEDs" on page 8 for information about these buttons and their functions. The Ethernet controllers on your blade server communicate with the network through the Ethernet-compatible switch modules on the BladeCenter unit. Network signals to and from the blade server or any I/O expansion cards are automatically routed to a same-network-interface switch module through circuitry in the BladeCenter unit. 68 BladeCenter HS40 Type 8839: Hardware Maintenance Manual and Troubleshooting Guide
