10/100 Fast Ethernet Switch User’s Guide
Overview
9
• Connect single users either to provide power users with greater access
and thus speed, or multiple users for high bandwidth access to a shared
network server.
• Uplink connections for lower-tier switches.
10/100Mbps Ports
The 10/100Mbps twisted-pair ports are standard RJ-45 connectors for use
with unshielded or shielded twisted-pair (UTP/STP) wiring. These ports are
auto-negotiating between 10Mbps and 100Mbps, which means that they
detect the speed of devices connected to them and auto-configure to run at
that speed. The 10/100Mbps ports also operate in half-duplex mode or full-
duplex mode at either speed. In either duplex mode, the twisted-pair ports
can operate over 100 meters of Category 5 UTP or STP cable.
Possible uses for the 10/100Mbps switch ports:
• Add Fast Ethernet segments to an existing 10Mbps LAN.
• Provide a dedicated Fast Ethernet connection for a shared LAN server in
a 10Mbps LAN.
• Uplink to a higher-tier hub or switch.
