Introduction

Cable Requirements

You can use Category 5 (Cat 5) Ethernet cables for 10 Mb/s and 100 Mb/s network connections to the BayStack 21 network card.

Use the following guidelines when using Cat 5 cables:

Maximum length between a workstation and a hub is 100 meters (m).

Maximum length between two hubs is 10 m.

Maximum length between two hubs which are functioning as Ethernet Class 2 Repeaters is 100 m.

Maximum total length between two workstations is 205 m.

Fast Ethernet Cables (100 Mb/s)

You must use a Cat 5 straight-through cable with one RJ-45 connector on each end for 100 Mb/s Ethernet connections. Do not use a crossover cable.

Ethernet Cables (10 Mb/s)

You can use Cat 3, Cat 4, or Cat 5 unshielded twisted pair (UTP) cable or an EIA/TIA-568 100 ohm shielded twisted pair (STP) cable for 10 Mb/s Ethernet connections. You must use a straight through cable with one RJ-45 connector on each end. Do not use a crossover cable.
