ABOUTTHISGUIDE

This guide provides all the information you need to install and use a SuperStack® II Switch 1100 unit with default settings. If you want to change the way the Switch works using management software, refer to the “SuperStack II Switch Management Guide” (part numberDUA1695-0BAA0x).

The guide is intended for use by network administrators who are responsible for installing and setting up network equipment; consequently, it assumes a basic working knowledge of LANs (Local Area Networks).

This guide is intended for use with both Switch 1100 models:

3C16950 — 24 10BASE-Tports

3C16951 — 12 10BASE-Tports

All pictures and example screens show the 24-portmodel, however, all procedures apply to the24-portmodeland the12-portmodel.

If the information in the release notes that are shipped with your product differs from the information in this guide, follow the instructions in the release notes.
