Industrial Ethernet Switch – JetNet 5428G / 5428G-DC / 5428G-2G-2FX

ethernet switch - JetNet5428G


The JetNet 5428G series, the 19-inch 24+4G Managed Ethernet Switch, is equipped with 24 10/100 Base-TX ports plus 4 Gigabit RJ45 / MINI GBIC combo ports (JetNet 5428G) and 2G combo and 2 Gigabit / 100M SFP sockets (JetNet 5428G-2G-2FX). The switches are special design for control rooms where high-port density and performance are required. The Gigabit Combo port design allows 10/100/1000 triple speed, and the SFP ports accept all types of Gigabit SFP transceivers, including Gigabit SX, LX, LHX, ZX and XD for several connections and distances.

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.
