NEC Express5800/120Rd-1’s system board includes a dual-channel gigabit network interface
controller based on the Intel 82546EB. The 82546EB is a highly integrated PCI LAN controller in a
21 mm2 PBGA package. The controller supports 10/100/1000 operation on both the channels and it
supports alert-on-LAN functionality.
The 82546EB controller supports the following features:
- 64-bit, 100MHz PCI-X interface
- Integrated IEEE 802.3 10Base-T, 100BASE-TX, and 1000Base-T 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, 100 Mbps and 1000 Mbps operation
- Low power +3.3 V devic e
The auto-sensing PRO/100+ Server Adapter from Intel can also be supported on NEC
Express5800/120Rd-1. By installing multiple PRO/100+ boards, high-availability (load balancing,
fault tolerance) and top perfor mance features are p rovided for the most demanding networking
environments.
NEC Express5800/120Rd-1 has an integrated ATI Rage XL PCI graphics accelerator with 8MB of video
SDRAM that supports all standard IBM VGA modes.
The embedded SVGA video subsystem supports:
- Pixel 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
NEC Express5800/120Rd-1 offers 2 free 64-bit/100MHz PCI slot:
1 slot is full length, other one is low p rofile.
These I/O slots ar e mounted on a PCI riser c a rd.
They are all Plug and P l a y ready and PCI connector s are parity enabled.
