The USB connectors located on the rear panel of the workstation provide an interface for
the keyboard and mouse to the system. These USB connectors support only the HP
keyboard, scroll mouse and hub. The keyboard and mouse may be plugged into the rear of
the workstation or plugged into the USB hub.
No
other USB configuration is currently
supported. Consult the documentation that accompanies each input device for specific
information concerning its use.
For more information on the Universal Serial Bus, refer to the following URL:
CAUTION
Usage of devices other than USB specification may result in unpredictable
functionality and inferior performance of the B1000/C3000 workstations.
NOTE
The USB clip on the rear of the chassis provides strain relief for the USB
cables.
HP Parallel I/O Connector
The 25-pin HP Parallel I/O interface uses IEEE 1284 I/O interface protocols to support
peripheral
devices
such
as
printers
and
plotters.
Consult
the
documentation
that
accompanies each peripheral device for specific information concerning its use.
802.3 Network Connectors
The B1000/C3000 workstations have a built-in Twisted Pair (TP) connector for the 802.3
(ETHERNET) or 10BaseT/100BaseT network. Connections to ThinLAN networks require
