D-Link announces 32-port 10/100M rackmount dual speed hub

D-Link, supplier of networking products, has announced the availability of its DFE -932RX 32-port 10/100M rackmount dual speed hub.

The DFE-932RX can operate with either IEEE 802.3 10BASE-T connections (twisted-pair Ethernet operating at 10 megabits per second), or IEEE 802.3u 100BASE-TX connections (twisted-pair Fast Ethernet operating at 100 megabits per second).

According to D-Link SA branch manager, Bertus Moller, all of the twisted-pair ports support NWay auto-negotiation, allowing the hub to automatically detect the speed of a network connection. "This means you can connect all of your Ethernet and Fast Ethernet hosts to any hub in the series, without any rewiring required when a host is upgraded from 10Mbps to 100Mbps."

"If you stack four 32-port hubs, it gives a total of 128 Ethernet or Fast Ethernet ports. A 32-port dual-speed stackable Ethernet/ Fast Ethernet Hubs stack operates as a Class II Fast Ethernet repeater, allowing it to be linked to another Class II Fast Ethernet stack in the same collision domain," explains Moller.

In the basic configuration, the 10Mbps and 100Mbps segments are separate but can intercommunicate and because each unit has built-in switch, it can intercommunicate in a stack of up to four units.

"An add-in module is also available, providing a 100BASE-FX connection. The hub in this series each has one slot for a slide-in module," concludes Moller.

Product features:

Compatible with the IEEE 802.3 10BASE-T Ethernet and 802.3u 100BASE-TX, 100BASE-FX Fast Ethernet industry standards for interoperability with other Ethernet/Fast Ethernet network devices.

Ethernet connections support Category 3 or better twisted-pair cables. Fast Ethernet connections support both shielded twisted pair and Category 5 unshielded twisted-pair cables.

Fast Ethernet connections support a maximum distance of 100 meters from end-station to hub, and a total network diameter of 205 meters. 32 NWay RJ-45 ports for connecting stations to the network.

Built-in switch allows bridging between 10Mbps and 100Mbps segments.

LED indicators for Power, FX Link/Rx, 100M Activity, 10M Activity, 10M Collision, 100M Collision, Switch Activity, 10M Link/Rx, and 100M Link/Rx. Two proprietary daisy-chain ports for stacking up to four hubs to form one logical hub.

Uplink port allows easy linking of two Fast Ethernet hub stacks to further expand your network.

Standard-size (19", 1U height), rack mountable Optional slide-in module: 100BASE-FX /SC, 100BASE-FX /ST
