1.3.20 Universal Serial Bus (USB)
The Universal Serial Bus (USB) provides a common interface to slower-speed peripherals. Functions such
as keyboard, serial ports, printer port, and mouse ports can be consolidated into USB, simplifying cabling
requirements. The cPB-4612 provides one USB port at its faceplate (connector J20 is Port 0). USB Port 1
and USB port 2 are routed to the cPB-4612’s J5 Rear Panel I/O connector.
The cPB-4612’s USB channels are controlled by the Intel 6300ESB device. The "Intel 855GME Chipset"
topic in Appendix D provides a link to the datasheet for this device.
1.3.21 System Environmental Monitor
This board provides an IMPI controller for monitoring the status of the system environment. The IPMI
controller monitors the system voltages, ambient board temperature, and CPU temperature. The controller
is accessed through an IPMB bus from the backplane.
See "System Monitoring and Control" in chapter 5 for more details.
1.3.22 LED Indicators
The LEDs located at the cPB-4612’s faceplate are defined below.
•
Ethernet (ENETA, RJ 45 connector):
First LED
:
Green = Network connection
Blinking Green = Network activity
Second LED
:
Off = 10 MB/sec
Green = 100 MB
•
Hot
Swap
Blue = safe to extract board
Off = not safe to extract board
1.4 Software
The cPB-4612 includes a DTI enhanced AMI Embedded BIOS loaded in on-board flash. The BIOS is user-
configurable and can boot an operating system from CompactFlash, a hard drive, CD-ROM drive, or over a
network. BIOS and firmware updates can be provided by DTI.
The cPB-4612 is compatible with all major PC operating systems, including Microsoft* Windows* 2000/XP,
Linux*, and VxWorks*. Chips may provide additional drivers for Intel peripherals, flash drives, and for
supported operating systems. Software device drivers for the cPB-4612 may be found on the DTI Product
Documentation and Software CD.
