)
- Segment B: 64-bit, 133 MHz, 3.3 V, full-length PCI (P64-B) supporting the following
configuration:
o Two slots: 64-bit, 100MHz PCI-X Slots (PCI-X Slot 3 and Slot 4)
o Single-channel Adaptec* AIC-7901 wide Ultra-320 SCSI Controller3
o Zero Channel RAID (ZCR) support. Also known as modular M-ROMB (Slot4)
- - Segment C: 64-bit, 133 MHz, 3.3 V, Full-length PCI (P64-C) supporting the
following configuration:
o Two slots: 64-bit, 100MHz PCI-X4 Slots (PCI-X Slot 15 and Slot 2)
• LPC (Low Pin Count) bus segment with two embedded devices:
- Baseboard Management Controller (BMC) providing monitoring, alerting, and logging
of critical system information obtained from embedded sensors on server board
- Super I/O controller chip providing all PC-compatible I/O (floppy, serial, parallel,
keyboard, mouse) X-Bus segment with one embedded device:
o Flash ROM device for system BIOS: Intel® 32 megabit 28F320C3 Flash
ROM
• Three external Universal Serial Bus (USB) ports on the rear of the board with an
additional internal header that provides two optional USB ports for front panel support.
• Two serial ports: One external serial port (Serial A) on the back edge of the board and
one internal header providing an optional Serial B
6
port.
• Two IDE connectors, supporting up to four ATA-100 compatible devices
• Six (two for redundancy) multi-speed system fans and two single speed CPU fans
• Multiple server management headers providing on-board interconnects to the board’s
server management features
• SSI-EEB3.0 compliant board form factor, the board size is 12 inch by 13 inch
2
NIC1 is the designated Server Management NIC.
3
Single Ended Mode not supported.

The BIOS is responsible for setting the mode (PCI or PCI-X) and bus speed for the two segments provided by the
P64H2. The actual bus mode/speed will be determined by the least capable card installed on that bus. The BIOS will
program the bus at 133MHz with one slot populated, and 100MHz when two slots are populated.
5
PCI slot 1 is designed to support a 2-slot PCI riser card, Segment C will run at a maximum of 100 MHz if a riser card is
used.
6
Serial B is the designated Server Management serial port.
