1. INTRODUCTION

This guide is intended for the system or network administrator responsible for installing and monitoring a Transition Networks’ pocket switch. A working knowledge of local area network (LAN) operations, including familiarity with communications protocols used on interconnected LANs, is assumed.

Transition Networks’ Pocket Switches

Transition Networks’ pocket switches (E-PSW-TX-02 and E-PSW-FX-02) provide a smooth network migration from legacy Ethernet™ 10BASE-T to Fast Ethernet 100BASE-TX or 100BASE-FX, supporting increasing network demands through incremental upgrades to existing network investments.
