The VP22 provides the standard 0.5 A at 5 V to the peripherals. Power on
each USB port is protected by a single polyswitch fuse (size 6 V/1.1 A, this
current rating allows for inrush currents). Additional ports can be added
through the use of an external USB hub.
PCI Expansion Slots
The VP22 supports four 32-bit, 33 MHz PCI expansion slots. These are
+5 V signaling slots that accommodate 5 V or universal PCI
boards.
Ethernet Interface
The VP22 provides a 10/100BaseTX Ethernet transceiver interface using
an Intel 82562EM integrated Ethernet device. The Ethernet interface is
accessed via an industry-standard, rear-panel-mounted RJ-45 connector.
The 82562EM chip is assigned an Ethernet Station Address. The address
is unique for each board (assembly) and is displayed on a label affixed to
the board. In addition, the Ethernet address is stored in the configuration
ROM interfaced to the 82562EM Ethernet device.
The Ethernet interface on the rear panel of the VP22 motherboard is
accompanied by two LED indicators.
