Input/Output Connectors And Devices - IBM BladeCenter HS20 Installation And User Manual

Input/output connectors and devices

The input/output connectors that are available to the blade server are supplied by
the BladeCenter unit. See the documentation that comes with the BladeCenter unit
for information about the input/output connectors.
The blade server has two selection buttons on the control panel: the media tray
select button and the keyboard/video/mouse select button. See "Understanding the
control panel and LEDs" on page 14 for information about these buttons and their
functions.
The Ethernet controllers on the blade server communicate with the network through
the Ethernet-compatible I/O-modules on the BladeCenter unit. Network signals to
and from the blade server or any expansion cards are automatically routed to a
same-network-interface I/O-module through circuitry in the BladeCenter unit.
