Connecting Network Devices
The EdgeIron 4802CF is designed to interconnect multiple segments (or
collision domains). It may be connected to network cards in PCs and
servers, or to hubs, switches or routers.

servers, or to hubs, switches or routers.
Note: Before connecting cables, you may want to first configure the
Spanning Tree Protocol to avoid network loops. Refer to the User
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.

is required; for 10BASE-T, Category 3, 4 or 5 cable can be used.
For 1000BASE-T connections, Category 5, 5e, or 6 (recommended) cable
is required with all four wire pairs connected. You should also test the
cable installation for IEEE 802.3ab compliance. See “1000BASE-T Cable
Requirements” on page B-5.

Cabling Guidelines
The RJ-45 ports on the switch support automatic MDI/MDI-X operation,
so you can use standard straight-through twisted-pair cables to connect to
any other network device (PCs, servers, switches, routers, or hubs).
