NEC N8100-1061F Server User Manual


 
General Description 2-19
PCI Riser Slots
The mother board has two PCI riser slots. Riser slot B provides the following features:
Bus speed up to 100 MHz
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 provides the following features:
Bus speed up to 66 MHz
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
Video
The mother board uses an ATI RADEON 7000 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 mother 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-7902 controller providing
dual Ultra320 Low Voltage Differential (LVD) SCSI channels.
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-LVDs devices generally are terminated through a jumper or
resistor pack on the device itself.
