The JetNet 5228G, a 19-inch 24+4G rackmount Managed Ethernet Switch, is equipped with 24 10/100 Base-TX ports plus 4 Gigabit RJ45 / MINI GBIC combo ports. It is a special design for building, control room and telecom applications where request high-ports density and performance. The device is mounted within the 19 inch rack, along with other 19 inch public servers or other network devices. It also supports Jumbo Frame, forwarding up to 9.2Kbps. Furthermore, the transmission of large files in industrial environments becomes more efficient and solid. The advantage of choosing the JetNet 5228G is that it supports 4 gigabit ports which allow users to trunk up to 8G uplink bandwidth, load balancing, path protection, to form network redundancy or apply MSTP to connect RSTP from different VLAN.

To fulfill the advanced management, control and security requests in industrial buildings and control rooms, the JetNet 5228G supports various advanced software features. The protocol VLAN, private VLAN, VLAN stacking, QoS, IGMP Snooping, layer 2/4 Access Control List, 802.1x, SNMP V3, LLDP, etc. complete the demand and greatly satisfy technicians’ requests. Furthermore, the low power consumption and the fan-less design enhance the benefits on the industrial requests.

Best choice for your Control Room
The JetNet 5228G is defined as the access level switch installed in the control room. Most buildings and control rooms are installed with different types of 19-inch managed or unmanaged switches where doesn’t request relatively higher operating temperature range or high level EMI/EMS protections due to the fact that it’s already well-protected from temperature effects, humidity and noises. The major concept to choose the JetNet 5228G for control rooms is the features and the cost-effective price.

The JetNet 5228G is a 19-inch design 24+4G rackmount managed Ethernet switch. The depth is simply 200mm with the fan-less design, the low power consumption and the 4 Gigabit combo ports. It provides advanced layer 2 management features, such as the Multiple Spanning Tree Protocol (802.1s), LLDP, 256 VLANs, Private VLAN, Access Control List (ACL)…etc.

High Bandwidth and Performance
JetNet 5228G supports 4 gigabit combo ports and up to 9,216 bytes jumbo frame.
Why 4 gigabit combo ports?

Act as the access switch, two gigabit ports for lower network, one or two for upper connection. The upper connection can be aggregated with up to 8G bandwidth in full duplex mode. 4 Combo Ports Design to save stock of storing different kinds of transceivers. 2 Gigabit ports for forming rings, the other 2 for connecting to public servers.

What is Jumbo Frame?

802.1s Multiple Spanning Tree Protocol
The JetNet 5228G supports 802.1s Multiple Spanning Tree Protocol (MSTP). The switch with MSTP enabled can select the root switch for each instance, block and form the forwarding path for each instance. Each instance represents for one VLAN. It is the limitation in STP/RSTP as the 2 traditional protocols only can block one path for all the existing VLANs in the same environment. 

Example: Instance 1 represent for VLAN 20. Instance represent for VLAN 10.
In instance 1, there are one root and one blocking path. The VLAN 20 data can be transmitted from switch 3 to 1 to 2 or vise versa.
In instance 2, there are another root and another blocking path. The VLAN 10 data can be transmitted from switch 3 to 2 to 1 or vise versa.

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, 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.

Multicast VLAN Registration (MVR) Multicast VLAN Registration (MVR) is a useful application to lower the multicast stream loading of the source port. In traditional multicast program, when hosts that belong to different VLANs require the same multicast programs, the source station copy the multicast data and forward to each VLANs through the same router port. The result is waste of the network bandwidth. To solve this problem, you can enable the MVR feature on 5228G. Assign the MVR multicast VLAN and available MVR multicast groups for the source station. Configure the MVR source or receiver for the ports. So that the hosts belongs to different VLANs can receive the same multicast program but can’t communicate with each other.

Advanced Security by Layer 2/4 Access Control List
In industrial building and control room installations, the 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 5228G equipped with one layer 2+ switch fabric which provides flexible ACLs for the specified subjects and operations within the same LAN.
