Korenix JetNet 5428G 24+4G-port Rackmount Managed Ethernet Switch w/4-port Giga Combo

The device is mounted within the 19 inch rack, along with other 19 inch public servers or other network devices. When the lower industrial switches are aggregated to the JetNet 5428G, the 24+4G design allows connecting up to 12 100M rings plus 2 copper/fiber gigabit or FE rings. Each of the ring has its own ring redundancy protection. This is a unique and Korenix patent protected ring technology.

JetNet 5428G is designed as a fan-less rackmount switch with low power consumption and wide operating temperature. JetNet 5428G-DC, the DC input model, allows 12-48VDC input. JetNet 5428G supports Jumbo frame featuring up to 9,216 bytes packet size for large size file transmission. This is the trend for future industrial application requests.

The embedded software supports RSTP and Multiple Super Ring technology for ring redundancy protection. Full layer 2 management features include VLAN, IGMP Snooping, LACP for network control, SNMP, LLDP for network management. Secured access is protected by Port Security, 802.1x and flexible Layer 2/4 Access Control List. With JetNet 5428G, you can fulfill the technicians’ need of having best solution for the industrial Ethernet infrastructure.

High Bandwidth and Performance

JetNet 5428G series support 24 fast Ethernet ports plus 4 gigabit combo (JetNet 5428G) and 2G combo and 2 Gigabit / 100M SFP (JetNet 5428G) ports as well as wire speed forwarding and up to 9,216 bytes jumbo frame. The 24+4G combo port design provides benefits and advantages when planning your industrial network architecture. Acting as the access switch, 100M speed is still the major and popular in industrial environment. Acting as the distribution switch, Gigabit Combo ports are designed for network redundancy, connecting public server or uplink path... 2 Gigabit ports are for forming independent ring, or connecting multiple switches with RSTP protection. 2 ports for ring and the others for connecting to public servers with higher bandwidth. The upper connection can be aggregated with up to 8G bandwidth in full duplex mode by LACP. Combo Port Design to save stock of storing different kinds of transceivers.

Maximum 12+2G Rings Aggregation Capability

Advanced Security by Layer 2/4 Access Control List 
In industrial building and control room installations, multi types of advanced security features are required and must be implemented. The secured access control list (ACL) makes it easy to limit certain devices communicating with the other addressed devices and by the specific protocol. Example rules include (1) the administrator to multiple stations, (2) stations to stations and (3)stations to public servers…etc.

The ACLs provide “Permit” and “Deny” rules for any or specific host. The IP address, MAC address and port ID are the destinations allowed to be applied the rules. The protocol ID, QoS tag, TCP flag… are the operations which users prefer to control. The JetNet 5428G series is equipped with one layer 2+ switch fabric which provides flexible ACLs for the specified subjects and operations within the same LAN.

Link Layer Discover Protocol 
The Link Layer Discover Protocol (LLDP) was formally ratified as IEEE 802.1AB-2005. LLDP is the Layer 2 protocol that allows the network device/station to advertise connectivity & management information, the identity & major capabilities. If receives and establishes network management information on the local same network.

In industrial environments, most vendors provide their own discovering protocols, window utility or other tools to manage their switches. The LLDP protocol fixes the interoperability among them. With LLDP supported, users can easily browse the network devices and establish the network management information schema about the stations.
