Page 8: Introduction
Chapter 1 Introduction The Compaq Netelligent 1108 100Base-TX Repeater (Part No. 267022-001) provides a high-speed solution to increasingly heavy network traffic and slow data throughput. The repeater uses the IEEE 802.3u, 100Base-TX standard to increase the speed of network transmissions by a factor of about 10. This enhanced performance greatly improves your network's efficiency. -

Page 21: Setting The Uplink Switch
Installing the Hub Setting the Uplink Switch The uplink switch lets you convert the repeater's 8th RJ-45 port to an uplinkable port so that you can interconnect two repeaters without the need for special crossover cables. The default setting for the switch is MDI-X (Media Dependent Interface-Reversed that is, standard repeater port). -
