Preface

Congratulations on your purchase of the GS-4012F/4024 Ethernet Switch.

This preface introduces you to the GS-4012F/4024 Ethernet Switch and discusses the conventions of this User’s Guide. It also provides information on other related documentation.

There are two GS-4012F models. The GS-4012F DC model requires DC power supply input of -48 VDC or -60 VDC, 1.2A Max. The GS-4012F AC model requires 100~240VAC/1.5A power.

About This User's Guide

This manual is designed to guide you through the installation and configuration of your GS-4012F/4024 for its various applications.

Syntax Conventions

•“Enter” means for you to type one or more characters. “Select” or “Choose” means for you to use one of the predefined choices.

•Command and arrow keys are enclosed in square brackets. [ENTER] means the Enter, or carriage return key; [ESC] means the Escape key and [SPACE BAR] means the Space Bar.

•Mouse action sequences are denoted using a comma. For example, “click the Apple icon, Control Panels and then Modem” means first click the Apple icon, then point your mouse pointer to Control Panels and then click Modem.

•For brevity’s sake, we will use “e.g.,” as a shorthand for “for instance”, and “i.e.,” for “that is” or “in other words” throughout this manual.

•The GS-4012F/4024 Ethernet Switch may be referred to as “the switch” in this User’s Guide.
