Installation Guide for the Model SW502 and Model SW507 Ethernet Switches
simple twisted-pair LAN, or as a multiport bridge. With its low port-to-port latency and high-
forwarding efficiency, the Ethernet switches can also be connected to other switching hubs.
The maximum distance between end-nodes is not restricted as it was with the traditional repeaters. By
dividing your network into smaller and more manageable segments, each linked to the larger network
with a switch, the maximum distance for communications between end-nodes is unlimited.
Features
The key features of the NETGEAR Model SW502 and Model SW507 switches are:
•
Conforms to the ISO/IEC 8802-3 and ANSI/IEEE 802.3 10BASE-T standard.
•
Conforms to the IEEE 802.3u 100BASE-TX standard.
•
Improves network productivity by segmenting network traffic or providing private 10 Mbps
access to the desktop or server, with no changes to the software or network interface.
− One 10 Mbps Ethernet port on the Model SW502 switch provides Bayonet-Neil Councelman
connector (BNC), attachment unit interface (AUI), or unshielded twisted-pair (UTP)
interfaces.
− Six 10 Mbps UTP Ethernet ports on the Model SW507 switch.
•
One additional UTP port running at 10 Mbps or 100 Mbps that can be configured as Normal
(MDI-X) or Uplink (MDI).
•
Switch-selectable half/full duplex. Doubles the throughput of point-to-point connections by
enabling individual ports to transmit and receive concurrently when the other end also supports
full-duplex.
•
Adaptive forwarding modes. Automatically switches the forwarding mode from cut-through
(minimizes network delay) to fragment-free cut-through, to store-and-forward (minimizes bad
packets) as network gets increasingly busy.
Minimum latency of packet transmission (leading edge to leading edge) less than 20 µ s.
•
•
Address learning function to build the routing information database. Routing table contains 4 K
entries per port to store MAC addresses for attached network nodes.
•
Wire-speed filtering and forwarding. Provides "traffic cop" function by directing traffic to the
appropriate route without slowing down the traffic.
•
Provides a 64 Kbyte buffer for each 10 Mbps port and a 160 K buffer for the 100 Mbps port.
