1 INTRODUCTION

OVERVIEW

The SMCGS1610 and SMCGS2410 are the first available unmanaged switches
that can be transformed into a smart switch with the use of a single button.
DHCP prevention combined with loopback detection and prevention, improves
the network environment and reduces network maintenance costs. The switches
also provide DoS attack protection, minimizing virus attacks and increasing
network uptime.

The SMCGS1610 and SMCGS2410 switches feature a non-blocking switching
architecture that forwards and filters packets at full wire-speed for maximum
throughput. The switches are compatible with all 10, 100, and 1000 Mbps
Ethernet devices because they are standard-based. The switches protect your
existing network investments while providing you with a straightforward
migration path to faster Gigabit speeds.

The SMCGS1610 and SMCGS2410 switches are plug-and-play devices; no
configuration is required. Auto MDI/MDI-X cable detection on all ports eliminates
the need for crossover cables. Each port can be used as an end-node or uplink
port, and any port can be simply plugged into a server, hub, router, or switch,
using straight-through or crossover cable. Diagnostic LEDs, which display link
status and activity, allow you to quickly detect and correct problems on the
network.

RJ-45 PORTS

The switch contains 16/24 1000BASE-T RJ-45 ports. All ports support automatic
MDI/MDI-X operation, so you can use straight-through cables for all network
connections to PCs or servers, or to other switches or hubs.

Each of these ports support auto-negotiation, so the optimum transmission
mode (half or full duplex), and data rate (10, 100, or 1000 Mbps) is selected
automatically.

Each port also supports IEEE 802.3x auto-negotiation of flow control, so the
switch can automatically prevent port buffers from becoming saturated.

SMART BUTTON

When the Smart button is engaged, the unmanaged switch automatically
initiates smart switch functionality. The Smart button enables the following
functions:

◆ DHCP Prevention - restricts installation of a DHCP server to port 1 only,

preventing rogue DOS servers from being connected to the network.

◆ Loopback Detection and Prevention - The switch checks all ports for a

loopback condition every 2 seconds. Upon detection of a loopback condition,
the switch blocks the affected port’s traffic for 3 seconds and flashes the

Loop On Red The switch has detected a loop condition and

disabled the appropriate port. When the loop
clears, the LED will turn off.
