Universal Serial Bus (USB) Interface
The baseboard provides two stacked USB ports (Port 0 on top, Port 1 on bottom). The built-in
USB ports permit the direct connection of two USB peripherals without an external hub. If more
devices are required, an external hub can be connected to either of the built-in ports.

ICMB Connectors
The external Intelligent Management Bus (ICMB) provides external access to IMB devices that are
within the chassis. This makes it possible to externally access chassis management functions, alert
logs, post-mortem data, etc. It also provides a mechanism for chassis power control. Optionally,
the server can be configured with an ICMB adapter board. This board provides two SEMCONN
6-pin connectors to allow daisy chained cabling.
