Dual Fast Ethernet Connector J6A/B; Floppy Drive Interface - Kontron CP6500-V User Manual

Functional Description
2.2.14

Floppy Drive Interface

The onboard floppy disk controller supports either 5.25 inch or 3.5 inch (1.44 or 2.88 MB) floppy
disks. The floppy disk port is only available on the CompactPCI rear I/O interface.
2.2.15 Fast Ethernet
The CP6500-V board includes two 10Base-T/100Base-TX Fast Ethernet ports based on the
Intel 82551ER Fast Ethernet PCI Controller, which is connected the PCI interface.
The Intel 82551ER Fast Ethernet Controller architecture is optimized to deliver high perfor-
mance with the lowest power consumption. The controller's architecture includes independent
transmit and receive queues to limit PCI bus traffic.
The Boot from LAN feature is supported.
The following figure illustrates the pinout and LED positioning of the J6A/B connector.

Dual Fast Ethernet Connector J6A/B

Note ...
The maximum length of cabling over which the Ethernet transmission can oper-
ate effectively depends upon the transceiver in use.
The Ethernet connectors are realized as RJ45 connectors. The interfaces provide automatic
detection and switching between 10Base-T, 100Base-TX and data transmission.
The two Fast Ethernet channels may be configured via the BIOS setting or the rear I/O config-
uration register for front I/O or rear I/O. The standard software configuration is front I/O.
RJ45 Connector J6A/B Pinouts
The J6A/B connector supplies the 10Base-T, 100Base-TX and interfaces to the Ethernet con-
troller.
