MAKING NETWORK

CONNECTIONS

Connecting Network Devices

The TigerSwitch 10/100 is designed to interconnect multiple segments (or collision domains). It may be connected to 10 or 100 Mbps network cards in PCs and servers, as well as to Ethernet and Fast Ethernet hubs, switches or routers. It may also be connected to remote devices using the optional 1000BASE-SX modules.

Note: Before connecting cables, you may want to first configure the Spanning Tree Protocol to avoid network loops. Refer to the Management Guide for more information.

Twisted-Pair Devices

Each device requires an unshielded twisted-pair (UTP) cable with RJ-45 connectors at both ends. For 100BASE-TX connections, Category 5 cable is required; for 10BASE-T, Category 3, 4 or 5 cable can be used.

Cabling Guidelines

Every twisted-pair connection must have a wiring crossover to transmit and receive data. For convenience, this crossover is built into all RJ-45 ports on the switch—these are fixed crossover ports (MDI-X). Since network cards do not cross their internal wiring to
