Quartet/440 TX provides ultimate performance for PCI servers operating on 10BASE-T Ethernet or 100BASE-TX Fast Ethernet technology. Quartet/440 TX supports up to four network segments on four independent channels-for cumulative throughput of 400 Mbits/sec., or 800 Mbits/sec. with Full Duplex operation. This high speed adapter multiplies flexibility, performance and Full Duplex capability by four to provide the easiest migration possible from 10BASE-T to 100BASE-TX Fast Ethernet.

AUTOSENSE CONFIGURATION PROVIDES FLEXIBILITY

The AutoSense feature of Quartet/440 TX allows the adapter to detect the maximum line speed of your network automatically. Simply connect the Quartet/440 TX into any existing 10BASE-T or 100BASE-TX network device, no adapter configuration required. For maximum flexibility, this AutoSense feature works with all 10 and 100 Mbits/sec. devices, including those without NWAY line speed negotiation.

DESIGN INNOVATION FOR FAST ETHERNET

There's no limit to how you can use your

Quartet/440 TX. Here are just a few examples.

PROVIDE A BRIDGE BETWEEN STANDARD 10 MBPS AND FAST ETHERNET.

Each Quartet/440 TX port configures line speed dynamically and automatically-connect one or more of the Quartet's ports to standard Ethernet hubs and printers, and connect the other ports to Fast Ethernet repeaters. The Quartet server bridges between network speeds for you. Choose the best port configuration for your network.

DOUBLE THE PERFORMANCE WITH FULL DUPLEX SUPPORT

Use a Quartet/440 TX with a Fast Ethernet switch to double the throughput of your server. Quartet/440 TX drivers easily configure to support Full Duplex operation at either 10 Mbits/sec or 100 Mbits/sec, for up to 800 Mbits/sec of bandwidth on a single network adapter.

MULTIPLE QUARTETS, NOT MULTIPLE SERVERS

Add a Quartet to your server and instantly gain four new segments. Streamline your network operations by adding multiple Quartet adapters to a single server. The bandwidth capacity of multiple Quartets means more room for growth, without adding expensive servers to your network.
