The input/output connectors that are available to the blade appliance are supplied by the BladeCenter unit. See the documentation that comes with the BladeCenter® unit for information about the input/output connectors.
The blade appliance has two selection buttons on the control panel: the media tray select button and the keyboard/video/mouse select button. See Blade appliance controls and LEDs for information about these buttons and their functions.
The Ethernet controllers on the blade appliance communicate with the network through the Ethernet-compatible I/O modules in the BladeCenter unit. Network signals to and from the blade appliance or any expansion cards are automatically routed to a same-network-interface I/O module through circuitry in the BladeCenter unit.
