OnLine introduces new infrastructure products

Extreme's Summit® 400-24 family of switches

Extreme's new Layer 3 fixed Gigabit Ethernet switches are designed for IP telephony, wireless and converged applications. The new Summit® 400-24 family of switches will provide its users with new UniStack™ stacking technology, Link Layer Discovery Protocol (LLDP) for simplifying device discovery and Extremes' AccessAdapt™ technologies to deliver native wireless LAN and IP telephony support.

According to OnLine, the new switches will benefit users in the Middle East. "The combination of the Summit switches with Extreme's Black Diamond modular switches will provide enterprises a leading edge as network managers can build an open converged network with higher availability in a simple two-tier design," said K. Ganesan, Divisional Director, OnLine Distribution "The Summit 400-24 switches are still consistent with Extremes approach to simplicity and flexibility."

Transition Networks' Industrial Hardened Media Converters and Switches

OnLine also announced the release of Transition's complete line of hardened media converters and switches designed for industrial Ethernet applications. These devices are designed to reliably operate in harsh networking environments found on factory floors, outdoor enclosures or other hazardous environments.

"As Ethernet makes the migration from office LANs to the factory floor, Transition offers its new hardened Industrial line of products as a compliment to its already extensive portfolio of industry leading, office-grade conversion products," said Ganesan. "Offered in multiple configurations and connector options, they easily represent one of the largest unmanaged switch offerings in the industry and are backed by an unsurpassed lifetime warranty."

The 10/100 copper Ethernet ports provide full 10/100Base-TX capability and support Auto-Negotiation and AutoCross (automatic MDI/MDI-X) while the fibre ports provide full 100Base-FX capability. The media converter model additionally offers Link Pass Through, which provides the ability to "pass through" the loss of Rx signal on one of the media ports to the Tx signal of the other media port. In addition, certain models incorporate Redundant Ring technology, which helps increase reliability and system uptime in an industrial automation network by protecting critical communication needs utilizing redundant fibre links with switching recovery times of less than 300ms.

All models offer redundant 12-48VDC power inputs with auto-sensing capability. In addition, dry contact relays are offered to provide alarming in the event of a port link failure or power supply failure. The rugged metal enclosure has an IP30 rating and comes standard with integrated DIN-rail mounting. All devices are UL safety rated and UL approved for use in Class I, Division 2 hazardous locations.
