Installation Guide for the Model SW510 and Model SW518 Ethernet Switches
Increased bandwidth is another advantage of the Model SW510 and Model SW518 switches. In
addition to 10 Mbps ports, each switch has two Fast Ethernet ports that create a high-throughput
connection to a backbone or server with 100 Mbps transmission. In addition to partitioning an
overloaded network, the switches provide a link between traditional 10BASE-T and the faster
100BASE-TX networks. All ports on the switches can operate in either full-duplex or half-duplex
data transfer mode to support the interconnection requirements of other high-speed devices.
Up to nine switching paths (18 paths in full-duplex mode) can be established at the same time,
with each path crossing two ports, performing switching that sends packets to the appropriate port
according to the destination address scanned from the packet header. This technique reduces the
latency of packet transmission to 75 microseconds ( s) or less. Compared to approximately 800 s
for a bridge or 1800 s for a router, the Model SW510 and Model SW518 switches deliver a major
improvement in the performance of your network.
Because the Model SW510 and Model SW518 switches are devices functioning on the media
access control (MAC) layer, they are protocol independent and are compatible with IEEE802.3,
IEEE802.3u, TCP/IP, NetWare, DECnet, and XNS protocols. Each of these switches can be
configured easily in most environments as a standalone device to form a workgroup consisting of
10 to 18 subnetworks or workstations, as a simple twisted-pair LAN, or as a multiport bridge. With
their low port-to-port latency and high forwarding efficiency, the Model SW510 and Model
SW518 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.
Dividing your network into smaller and more manageable segments, each linked to the larger
network with a switch, creates a maximum distance for communications between end nodes that is
unlimited.
Features
The Model SW510 and Model SW518 switches have the following key features:
•
Use in segment or desktop applications
Network productivity is improved by segmenting network traffic or providing private 10 Mbps
access to the desktop or server, with no changes to the software or network interface.
•
Eight 10 Mbps unshielded twisted pair (UTP) Ethernet ports on the Model SW510 switch;
Sixteen 10 Mbps UTP Ethernet ports on the Model SW518 switch
One of the 10 Mbps UTP ports is configurable as Normal (MDI-X) or Uplink (MDI).
