Chapter 1. Fundamentals SK-NET Gigabit Ethernet Server Adapters combine servers and workstation computers with the high- speed Gigabit Ethernet network (1000 Mbit/s) using fiber-optic (FO) or copper cables. At present there are eight types available. They differ in terms of the number of ports and the transmission mode. SC duplex connectors, VF-45 connectors (FO) or RJ-45 connectors (copper cabling) are used to connect to the data network. The adapters can be connected to a switch, a buffered

Chapter 1. Fundamentals Features For the SK-NET GE dual link types: Redundant Link Management (RLMT) for Fault Tolerance The two Gigabit Ethernet ports offer dual homing similar to that found in FDDI technology. In order to provide greater fault tolerance the Gigabit Ethernet Server Adapter is connected to two switch ports. These ports may be on the same switch or on two switches in different physical locations. Only one port is active at any one time but both links are monitored. The second p

Chapter 1. Fundamentals For all SK-NET GE types: 64-bit/66 MHz PCI Bus Interface Although designed as a 64-bit/66 MHz PCI bus interface, the Gigabit Ethernet Server Adapter can also be operated in 32-bit systems or at a clock frequency of 33 MHz. The cards operate as true Plug & Play adapters and automatically adjust to the different configuration options on the PCI bus. The high-speed 64-bit/66 MHz PCI bus is now state-of-the-art in high-end server systems. The theoretical bandwidth is four

Chapter 1. Fundamentals Gigabit Ethernet Server Adapters can use interrupt moderation to group these interrupts so that several data packets can be handled per interrupt. • Task Offload – Integrated Intelligent Functions Calculation of TCP, UDP, and IP checksums is CPU-intensive and is normally performed by the host CPU running the TCP/IP stack. These calculations are integrated in the hardware of the Gigabit Ethernet Server Adapters. The checksums are calculated without time loss in SysKonnect’

Chapter 2. Connecting the Network Card to the Data Network 2. Follow the safety instructions. If possible, disconnect the switch and the computer from the power supply. If you are hot plugging, you should also follow the safety instructions issued by the system vendor. 3. Remove the protective plug from the switch port which is to be used. 4. Connect the SC duplex, VF-45 or RJ-45 connector at one end of the cable to the port on the switch. 5. Remove the protective plug from the (lower) port

Chapter 2. Connecting the Network Card to the Data Network 7. Switch on the computer and the switch. If a protocol driver has not been loaded, go to Chapter 3. After driver installation, return to the next step of this list. If a protocol driver has been loaded, continue with the next step. 8. Check for correct polarity using the green Link LED (see Fig. 4) on the network card. Constant green: connection established and active. Link RX TX Flashing green: connection established and on standby.

Chapter 2. Connecting the Network Card to the Data Network Note: The lower port on the network card (marked A) is normally active; the upper port (B) is the backup port. The procedure for setting up a dual homing connection is as follows: Setting up the active connection 1. On the switch, select the port that will be used in normal operation to handle the active connection. 2. Connect this port to the lower port (A) on the dual link network card, following the instructions for Single Connectio

Chapter 3. Installing Protocol Drivers from the CD-ROM Installing Network Drivers (Protocol Drivers) The protocol drivers are located in the appropriate product directory on the CD-ROM. This directory is organized into a number of subdirectories for the various operating systems. For instructions on how to install the drivers please read the relevant Readme files. These files are available as ASCII text and in HTML format. Any last-minute changes are documented in the Release Notes and on the Sy

Chapter 4. Troubleshooting Testing the Network Card You can test the network card with the aid of the diagnostics program supplied (running on DOS). The available test modes are as follows: • Simple test without loopback: this test covers all the components but not the port (socket incl. components for transmitting/receiving the data signals). • Comprehensive port testing with loopback: all the components are tested, including the port. • For dual link network cards there is also a port-to-port
