Install Guide

Introduction

This guide describes the installation of the MIL-5008H hub and its integration into
a network. It covers unpacking the product, connection of power, cabling
requirements and connection to the RJ-45 ports, and installing the optional feet
and rack mount ears. In addition, this guide describes the meaning of the LEDs,
provides trouble shooting suggestions, and a theory of operation of the MIL­5008H.

The MIL-5008H complies with the IEEE 802.3u standard for 100BASE-TX class II
hubs supporting half duplex, 100Mbps bandwidth. Each port supports auto
partitioning with reconnection after fault correction.

The LEDs easily update the user on the status of the hub. This includes collision
and power status, link integrity, data reception, and port partitioning.
