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
repeater, or directly to a second station (see also Fig. 1).

Computers in which the adapter is to be installed must have one free slot that complies at least with
PCI specification v2.0. A 32-bit or a 64-bit PCI bus running at 33 or 66 MHz may be used. Optimum
performance is generally obtained with a 64-bit/66 MHz PCI bus.
