Overview

The DES-108 Fast Ethernet Switches provide a quick, easy and economical way to add high speed networking to home offices, small and medium businesses. With data transfer speeds of up to 200 Mbps the DES-108 are ideal for fast file transfers.  They provide five or eight ports for easy expansion of your network for connecting printers,scanners,storage, and backup devicesto any network.

Robust Design

The DES-108 are designed with durability and performance in mind. Their sturdy metal housing ensures the product can withstand extreme temperatures and can be placed in typical industrial environments such as factories, construction and mining. They help to dissipate heat and reduce stress on internal components.

Effortless High Speed Networking

They are easy access, auto-sensing 10/100 front Ethernet ports with two LED indicators per port to quickly distinguish link status and speed. The DES-108 switches also support Auto MDI/MDIX Crossover allowing each port to be plugged directly to a server, hub, router, or switch using regular straight-through twisted-pair Ethernet cables. Support for IEEE 802.1p QoS is included, which organises and prioritises time-sensitive and important data for efficient delivery.
