JetNet 4010 is an industrial Managed Fast Ethernet Switch, designed with 7-10/100TX and 3-10/100
RJ-45 / 100FX SFP combo ports. The flexible 3 combo ports offer flexibility for additional fiber connections by plugging different types of 100MM SFP modules, which can support 2KM in Multi-Mode or 120KM in Single-Mode. The combo ports make port combination even easier, such as 8 RJ ports and 2 fiber ports, or 9 RJ ports and 1 fiber port. The standard 10 port Fast Ethernet switch greatly reduces total cost by up to 15% for fiber uplink network.

In addition to cost savings, the flexible design of the JetNet 4010 can adapt to the world's fastest Ring
Technology by Korenix. It only takes 5ms to recover from link failure, no matter how many nodes are
inside a ring, and the restore time is zero when the failed link is recovered. The patented Multiple Super
Ring provides the most flexible ring topologies, such as shared link of multiple rings, or shared unit
of multiple rings, making it the best possible. The Multiple Super Ring is highly compatible to Rapid
Spanning Tree by the new Dual Homing plus design. JetNet 4010 also enhances security designs, such as
SSH, 802.1X, etc.

3 Flexible Fast Ethernet Combo Ports
The JetNet 4010 is designed with three combo Fast Ethernet ports. Each combo port combines one Small
Form factor Pluggable (SFP) socket for 100Mbps multimode or single mode SFP transceiver, as well
as one RJ-45 copper port in 10Mbps full duplex, 100Mbps half /full duplex link mode. The switch will automatically detect the priority of cable connections for each combo port. Users are able to connect two 100Mbps SFP ports of JetNet 4010 as a Fast Ethernet Fiber Redundant Ring topology and the third combo port as a fiber uplink port or an applicable port.

Comprehensive Redundant Solutions- Multiple Super Ring (MSR) Technology
The JetNet 4010 supports MSR (Multiple Super Ring) the next new generation of RSR (Rapid Super Ring) Ring technology. This new technologies is perfect for different network redundancy applications and structures. With the MSR technology, a node can be configured to multiple rings with the failover time in as little as 5ms and ZERO-second restore time. In addition, users can extend the ring topology by adding hundreds of JetNet 4010 to meet the network needs without compromising the speed of the network.

The MSR also facilitates the JetNet 4010 to connect with core management switch via standard Rapid Spanning Tree Protocol or through multiple paths or nodes to increase the reliability by Rapid Dual Homing (RDH) Technology. By integrating MSR and Link Aggregation Control Protocol (LACP) the JetNet 4010 can enhance the link availability and to increase the link capacity. Two or more Fast Ethernet connection are bundled in order to increase the bandwidth and to create resilient and redundant links.

Rapid Dual Homing (RDH) Technology
Rapid Dual Homing (RDH) replaces DualHoming II and can be used for ring coupling. While keeping easy
configuration and multiple redundancies, the failover time is much faster (less than 50 ms) and the restore
time is ZERO (seamless restoration). Uplinks can be auto detected and gathered into groups. In each group, uplinks are sorted into Primary, Secondary, and Standbys by their link speed. The uplink with the
highest speed is more likely to be the active path for data transmission. Link aggregation is also integrated
into RDHTM. An uplink can be a link or several links aggregated as a trunk, which provides better redundancy and link capacity.
