CHAPTER 1: INTRODUCTION This installation guide describes the NETGEAR FS726 and FS750 Modular Fast Ethernet Switches. NETGEAR’s FS726 and FS750 are expandable, high-performance, IEEE-compliant network switches designed for users who require a large number of ports and want the high-speed capability of 10/100 switching to eliminate bottlenecks, boost performance, and increase productivity. Both switches are designed with front module bays that will accommodate either copper gigabit modules or fiber gigabit modules for high-speed connection to a server or your network backbone. Built-in modularity gives you the flexibility to buy according to your immediate needs, then add to your system later. You can purchase the optimal combination of copper and fiber gigabit modules for your network – both the same or one of each, as either will function in each module bay. To simplify installation, both switch models are shipped ready for use, with no configuration required. Everything necessary for setup comes in the box. This chapter provides the following information: • Description • Features • Package contents
Description NETGEAR’s FS726 and FS750 Modular Fast Ethernet Switches are flexible, powerful, and easy-to-use network solutions. Both switches have two front panel module bays that can be used with gigabit uplinks to create a high-performance backbone connection. Each module bay accepts either a copper Gigabit Ethernet module (1000BASE-T,
