1-12 System Overview
Autodetect and autoswitching for 10 or 100 Mbps network speeds
Support for both 10 Mbps and 100 Mbps networks, capable of full or half
duplex, with back-to-back transmit at 100 Mbps.
The network status LEDs on the system board, which are visible from the rear of the
chassis indicate:
Transmit/receive activity on the LAN
Valid link to the LAN
10/100 Mbps transfer mode.
SCSI Controller
The system board includes an embedded Adaptec AIC-7896 dual function SCSI
controller. The Adaptec AIC-7896 contains one independent Ultra2 (LVD) wide and
one Ultra wide SCSI interface that share a single PCI bus master controller.
No logic, termination, or resistor loads are required to connect devices to the SCSI
controller, other than termination in the device at the end of the cable. This system can
be cabled from either of the two onboard SCSI interfaces to the SCSI backplane on the
rear of the hot swap chassis were termination is provided on the SAF-TE board.
Video Controller
The system has a high-performance SVGA subsystem that supports the following:
BIOS compatibility with VGA, EGA, CGA, Hercules Graphics, and MDA
2 MB of Video Random Access Memory (VRAM) video buffer
16-bit bus for high-speed display memory access
Hardware accelerated bit block transfers (BITBLT)
Display power management system
Supports 72Hz refresh, non-interlaced at: 640x480, 800x600, 1024x768, or
1280x1024 resolutions
Displays of up to 16M colors at 640x480 and 800x600 resolutions, 64K colors at
1024x768 resolutions and 256 colors at 1280x1024 resolutions.
