The iConverter 4GT is a compact 4-Port Ethernet switch module and is a member of the managed iConverter product family. The plug-in module offers networking features including rate-limiting, traffic classification and prioritization, and VLAN capability.

The four RJ-45 ports support 10/100/1000Mbps bridging, Half/Full-Duplex and auto-negotiation. These features are configurable using DIP-switches or through software management. The 4GT supports RJ-45 auto-crossover (MDI/MDI-X) on all four ports, eliminating the need for a crossover cable.

The iConverter 4GT supports the IEEE 802.1Q tag Virtual Local Area Network (VLAN) packet tagging and untagging (including Q-in-Q) and the 802.1p Quality of Service priority standards.

4GT VLAN 802.1ad tunneling technology enables service providers to offer their customers E-Line and E-LAN services (via Ethernet Virtual Circuit or EVC), which connect multiple business LANs at different locations and make their networks appear to be on the same local network. Q-in-Q Service tags transparently transport customer network traffic across the service provider network, isolating it from other customer and service provider management traffic.

The 802.1p prioritization standard enables delivery of Quality of Service (QoS) to high-priority, real-time applications such as voice and video over Ethernet.

The 4GT supports traffic prioritization according to Class of Service (CoS) prioritization scheme. Incoming frames are assigned to one of four egress queues based on the VLAN tag P-bit value. This allows high priority traffic, such as voice traffic, to egress the network with no impact from lower priority traffic during congestion.

The iConverter 4GT switch is available as compact, unmanaged standalone unit, or chassis plug-in module that can be managed with a Management Module (NMM2) or Network Interface Device (NID) installed in the chassis. The management module provides access to the advanced features available on the module.

The 4GT standalone unit is available with an external AC to DC power adapter or with a 2-pin terminal connector for direct connection to DC power. The standalone module can be DIN-Rail mounted using the optional DIN-Rail mounting clips (8251-0).

The hot-swappable plug-in module can be mounted in a 19 or 5-Module iConverter chassis with redundant AC and DC power supplies. It can also be mounted in a 2-Module AC or DC powered chassis, or in a 1-Module chassis with AC or DC power input.
