4-, 8-, AND 16-PORT SERVSWITCH EC SERIES IP KVM SWITCH

2. Overview

2.1 Introduction

The 4-, 8-, and 16-Port ServSwitch™ EC Series IP KVM Switches allow you to use
the Internet or your TCP/IP enabled network to remotely monitor and control
critical PC servers and workstations using an industry-standard Web browser or
VNC client. Or, use On-Screen Display (OSD) or hotkeys to manage the switch.

The ServSwitch supports industry-standard networking and management protocols
such as TCP/IP and SNMP. It offers secure management options including SSL
encryption, SSH tunneling, and RADIUS. The ServSwitch is platform-independent
and can be managed using any Java™ enabled Web browser.
