Chapter 2: Overview

2. Overview

2.1 Introduction

The Switch provides (16) or (24) 10-/100-/1000-Mbps RJ-45 ports and can

support (4) Combo SFP ports for uplink. The switch is easy to install and provides

high performance in an environment where traffic on the network and the

number of users increases continuously. The switch uses the latest Gigabit chipsets

providing it with the best performance and features available; this enables the

switch to support full-duplex Gigabit speed on every port without any issues.

The switch also provides MDI/MDI-X automatic crossover detection on every port,

so it connects to another switch without crossover cable.

The 19" rackmount size makes the switch a perfect fit for medium to large work-

groups. It fits easily into your existing 19" racks and only uses 1 rack unit (RU) of

space. Because the switch is unmanaged, it’s easy to install. Just install the switch

in your rack or cabinet and you are ready to connect up to 16 more devices to

your network.

2.2 Features

• Complies with the IEEE 802.3 Ethernet, IEEE 802.3u Fast Ethernet and IEEE

802.3ab Gigabit Ethernet standards.

• Provides (16) or (24) 10-/100-/1000-Mbps Gigabit switching ports

and (4) Combo SFPs.

• 19" rackmount size.

• Supports non-blocking and non-head-of-line blocking full-wire-speed

forwarding.

• Supports store-and-forward operation.

• Features an embedded 500 KB packet buffer.

• Supports 9.6 KB JUMBO packets

• Provides 8K MAC address entry.

• Supports broadcast storm filtering.

• All ports provide autonegotiation and Auto-MDI/ MDI-X functions.

• Supports flow control: backpressure for half-duplex and IEEE 802.3x for

full-duplex mode.

• Smart plug-and-play.
