General Description 2-19

SCSI Controller

The baseboard includes an embedded Adaptec AIC-7902, which contains two independent channels.
You can enable or disable the SCSI controller in BIOS Setup. Both channels support 16-bit SE or
LVD SCSI operations at the following speeds:

„

Ultra320 (320 MB/sec)

„

Ultra160 (160 MB/sec)

„

Ultra 2 (80 MB/sec)

„

Ultra Wide SE (40 MB/sec)

The baseboard provides active terminators, termination voltage, resettable fuses, and protection
diodes for both SCSI channels. You can disable the onboard terminators in BIOS Setup.

Network Interface Controllers

NOTE:

To ensure EMC product regulation compliance, the system

must be used with shielded LAN cables.

The baseboard includes two network interface controllers (NICs):

„

Intel 82550 NIC that supports 10Base-T and 100Base-TX networks

„

Intel 82544 NIC that supports 10Base-T, 100Base-TX networks, and 1000BASE-T
networks

The 82550 controller supports the following features:

„

32-bit PCI

„

Integrated IEEE 802.3 10Base-T and 100Base-TX compatible PHY

„

IEEE 820.3u auto-negotiation support

„

Chained memory structure similar to the 82559, 82558, 82557 and 82596

„

Full duplex support at both 10 Mbps and 100 Mbps operation

„

Low power +3.3 V device

„

IP checksum off-loading

NIC 1 can be used as both a network interface and server management interface.
