Service: Upgrading the Hardware for additional information. The controller automatically detects, sizes, and initializes the memory array, depending on the type, size, and speed of the installed DIMMs, and reports memory size and allocation to the server via configuration registers. NOTE Use DIMMs that have been tested for compatibility with the server board. Contact your sales representative or dealer for a current list of approved memory modules. PCI Riser Slots The server board has two PCI riser slots. Riser slot B (item D in Figure 2-5) provides the following features: • 184-pin, 5-volt keyed, 64-bit expansion slot connector • Support for a 3-slot PCI riser card • Support for both full-length and low-profile PCI cards Riser C (item K in Figure 2-5) provides the following features: • 184-pin, 5-volt keyed, 64-bit expansion slot connector • Support for a 3-slot PCI riser card • Support for only low-profile PCI cards • RADIOS enabled for use with zero channel RAID cards (SCSI version only) Video The server board uses an ATI RAGE XL PCI graphics accelerator with 8 MB of video SDRAM. The embedded SVGA video subsystem supports: • Resolutions up to 1600 x 1200 under 2D and 1024 x 768 under 3D • CRT and LCD monitors up to 100-Hz vertical refresh rate The server board supports disabling of the onboard video through the BIOS setup menu or when a plug-in video card is installed in any of the PCI slots. SCSI Controller The SCSI version of the server board includes an embedded Adaptec AIC-7902W controller providing dual Ultra-320 Low Voltage Differential (LVD) SCSI channels to the two internal SCSI drive bays. Channel B is routed to the two internal SCSI drive bays. Channel A is routed to the external U-320 connector. The SCSI bus is terminated on the server board with active terminators that cannot be disabled. The onboard device must always be at one end of the bus. The device at the other end of the cable must also be terminated. LVD devices generally do not have termination built-in and need to have a termination source provided. Non-LVD devices generally are terminated through a jumper or resistor pack on the device itself. Network Controller NOTE To ensure EMC product regulation compliance for intra-building lighting surges, the server must only be used with shielded LAN cables that are grounded at both ends. The server board uses the Intel Fast Ethernet Controller 82546EB and supports two 10Base-T/100BaseT/1000Base-TX network subsystems. 24 Chapter 2

Service: Upgrading the Hardware for additional information.
The controller automatically detects, sizes, and initializes the memory array, depending on the type, size,
and speed of the installed DIMMs, and reports memory size and allocation to the server via configuration
registers.
NOTE
Use DIMMs that have been tested for compatibility with the server board. Contact your sales
representative or dealer for a current list of approved memory modules.
PCI Riser Slots
The server board has two PCI riser slots. Riser slot B (item D in Figure 2-5) provides the following features:
•
184-pin, 5-volt keyed, 64-bit expansion slot connector
•
Support for a 3-slot PCI riser card
•
Support for both full-length and low-profile PCI cards
Riser C (item K in Figure 2-5) provides the following features:
•
184-pin, 5-volt keyed, 64-bit expansion slot connector
•
Support for a 3-slot PCI riser card
•
Support for only low-profile PCI cards
•
RADIOS enabled for use with zero channel RAID cards (SCSI version only)
Video
The server board uses an ATI RAGE XL PCI graphics accelerator with 8 MB of video SDRAM. The
embedded SVGA video subsystem supports:
•
Resolutions up to 1600 x 1200 under 2D and 1024 x 768 under 3D
•
CRT and LCD monitors up to 100-Hz vertical refresh rate
The server board supports disabling of the onboard video through the BIOS setup menu or when a plug-in
video card is installed in any of the PCI slots.
SCSI Controller
The SCSI version of the server board includes an embedded Adaptec AIC-7902W controller providing dual
Ultra-320 Low Voltage Differential (LVD) SCSI channels to the two internal SCSI drive bays. Channel B is
routed to the two internal SCSI drive bays. Channel A is routed to the external U-320 connector.
The SCSI bus is terminated on the server board with active terminators that cannot be disabled. The
onboard device must always be at one end of the bus. The device at the other end of the cable must also be
terminated. LVD devices generally do not have termination built-in and need to have a termination source
provided. Non-LVD devices generally are terminated through a jumper or resistor pack on the device itself.
Network Controller
NOTE
To ensure EMC product regulation compliance for intra-building lighting surges, the server
must only be used with shielded LAN cables that are grounded at both ends.
The server board uses the Intel Fast Ethernet Controller 82546EB and supports two 10Base-T/100Base-
T/1000Base-TX network subsystems.
