DES-1024R+

Top: DES-1016R+ switch with 16 auto-sensing 10/100Mbps ports. Bottom: DES-1024R+ switch with 24 auto-sensing 10/100Mbps ports. Each switch is equipped with an open slot (on the front) for you to fit in an optional 2-port 100Mbps Fast Ethernet fiber module.

10/100Mbps Switches for Workgroups

These unmanaged 10/100Mbps switches are designed to enhance workgroup performance while providing a high level of flexibility. Powerful yet easy to use, these devices allow users to simply plug any port to either a 10Mbps or 100Mbps network to multiply bandwidths, boost response time and satisfy heavy load demands.

Choices of 16 or 24 10/100Mbps Ports

Two choices of switches are available: one with 16 10/100Mbps ports, the other with 24 10/100Mbps ports. These ports detect the network speed and autonegotiate between 100BASE-TX and 10BASE-T, as well as fulland half-duplex.

Auto-adjustment of MDI/MDIX Cross Over

All 10/100Mbps ports auto-adjust MDI/MDIX twistedpair cable cross-over, eliminating the need for crossover cables or uplink buttons. You simply plug any port to a server, a workstation or a hub, using the usual straight-through twisted-pair cable. The port will autosense the attached device type and adjust the Tx, Rx pin assignments accordingly before transmitting and receiving data.

Optional 100Mbps Fiber Ports

An open slot is provided on the front panel to let you install an optional Fast Ethernet fiber module. This module provides 2 100Mbps fiber ports for 2 server connections or switch-to-switch cascading over the reliable fiber cables, which can be up to 2km long.

Key Features

Flow Control Protects Against Data Loss

Using flow control (in full duplex and applicable to all 10/100Mbps ports), the switch monitors the buffer status of each port. During peak usage, if the buffer fills to capacity, the switch detects this and signals to the attached node to delay sending new data until the switch can accept it. This operation minimizes the chance of any buffer overrun where incoming data overwrites the current data that has not been completely flushed out of the buffer. This function works with flow control supported Fast Ethernet adapters (installed in servers) connected to the switch in dedicated bandwidth configuration. It can also be applied to switch-to-switch cascading.

Easy Expansion

Cascading 2 switches together to expand the network using the twisted-pair ports is easy. As all 10/100Mbps ports support auto-negotiation of MDI/MDIX twisted-pair cable cross-over, you simply connect 2 switches together without having to find a cross-over cable or to make sure the ports are

uplink ports. At 200Mbps full-duplex speed, all ports provide a fast switch-to-switch dedicated bandwidth. 16 or 24 10/100Mbps ports
