1.What is a server NIC? (Back to top)
Server NICs are network cards designed to handle high volumes of data
throughput. They also often include multiple port load balancing or
standby backup functions.
2.What is the DGE-500SX? (Back to top)
The DGE-500SX is a Gigabit NIC, which means that it has a 1000Mbps data
throughput rate. It uses a multimode SC fiber optic connector and is based
on the Level-One LXT1001 GMAC.
3. Does the DGE-500SX include any indicators or external controls?
(Back to top)
This NIC has four LEDs for: Full Duplex, Link, Transmit/Receive, and
1000Mbps.
4. Does the DGE-500SX support VLAN tagging? (Back to top)
Yes. The DGE-500SX is fully VLAN ready.
5. Does the DGE-500SX support IEEE 802.3x flow control? (Back to top)
No. The current version does not support flow control.
6. Does the DGE-500SX support Chip-Level Internet Protocol (CLIP)?
(Back to top)
Yes. The DGE-500SX is built around a Level-One GMAC that supports CLIP.
7. What is CLIP? (Back to top)
Chip-Level Internet Protocol is a means for the GMAC itself to handle
IP checksum tasks. The benefit of this feature is reduced host CPU
processing overhead (and resulting increased PC performance).
8. What is a GMAC? (Back to top)
A Gigabit Media Access Controller is a chip designed to control a
network device, such as a NIC, that runs at 1000Mbps (or 1Gbps).
9. What is a multimode SC fiber optic connector? (Back to top)
Multimode refers to the ability of the connector to handle the
propagation of multiple frequencies of light. SC stands for "socket
contact," which means that the cable connector and the fiber optic port
come into direct contact. This is a bipolar connector, which means that
the send and receive ports are not interchangeable. Cables must be
properly matched to the ports (send-to-send, receive-to-receive).
10. What is the maximum data transmission range of the DGE-500SX?
(Back to top)
Two cable types are supported, each with a different maximum range:
- For 850nm 62.5/125 cable : 220 meters
- For 850nm 50/125 cable : 500 meters
11. What OS driver support is provided for the DGE-500SX? (Back to top)
Driver support is currently (as of 10 Jan 2000) provided for:
- Windows 95 NDIS3
- Windows 98 NDIS5
- Windows NT 4.0 NDIS4
- Windows 2000 Beta NDIS5
- Linux OS Kernal v2.0/2.2
- Netware v4.11/4.2/5.0
12. Is there a difference between the SC socket's two connectors on the
DGE-500SX? (Back to top)
Yes. The connectors are bipolar. The upper one is for transmit and the
lower one is for receive. Together the two connectors make up one fiber
optic port.
13. Where can I best make use of a Gigabit NIC? (Back to top)
Gigabit Ethernet cards work excellently to open up server throughput
bottlenecks.
