H3C IE4320 Series Industrial Ethernet Switch Rack Mount Fanless Cooling

H3C Industrial Ethernet 4320 switch series is H3C's latest industrial Ethernet switches designed for rugged environment and wide operating temperature. IE4300 industrial switch series use the new H3C independent intellectual property operating system Comware V7, while ensuring rich software features, it further provides powerful hardware protection capabilities, which can work for a long time in the harsh environment of -40℃~85℃, it has IP40 protection level and no fan cooling performance.

H3C IE4320 industry switches series includes the following models:

• IE4320-28F: 24 x 100/1000BASE-X SFP Ports (8 combo ports), 4 x 1G/10GBASE-X SFP+ Ports, AC+AC;
• IE4320-28S: 24 x 10/100/1000BASE-T Ethernet ports (8 combo ports), 4 x 10G BASE-X SFP+ ports, AC+AC;
• IE4320-28S-HPWR: 24 x 10/100/1000BASE-T Ethernet ports (16 ports support PoE+, 8 ports support PoE++), 4 x 10G BASE-X SFP+ ports, DC+DC;

H3C IE4320 series industrial switches have multiple reliability protections at the device level and link level. It adopts a fanless heat dissipation energy circuit design, and through multiple heat dissipation structures such as built-in heat sinks and heat dissipation guides, it can perform consistently in various harsh environments, and the operating temperature range can reach -40°C~75°C. It supports lightning protection and can adapt to a variety of outdoor harsh environments.

Apart from device level redundancy, H3C IE4320 series industrial switches also provides diverse link redundancy support such as LACP/STP/RSTP/MSTP/Smart Link protocols. It supports IRF2 and 1: N redundancy backup as well as cross-device link aggregation which substantially increases network reliability.

H3C IE4320 series industrial switches make switch management with ease with the support of SNMPv1/v2/v3, which can be managed by NM platforms, such as Open View and iMC. With CLI and Telnet switch management is made easier. And with SSH 2.0 encryption, switch management security is enhanced.

H3C IE4320 series industrial switches support VLAN division based on MAC address, which solves the intelligent and flexible management of mobile office. Combined with the unique global and VLAN-based ACL distribution policy, it simplifies user configuration and greatly saves hardware resources.

H3C IE4320 series industrial switches adopt new energy-saving chips and innovative architecture design solutions to achieve low power consumption of gigabit switches, bring users green, environmentally friendly and energy-saving new network access products, and reduce user maintenance costs. At the same time, H3C IE4320 series industrial switches adopt a variety of green energy-saving designs, including auto-power-down (port automatic energy-saving). If the interface status is always down for a period, the system will automatically stop power supply to the interface and automatically enter the energy-saving mode; Supports EEE energy saving function. If the port is idle for a period, the system will set the port to the energy saving mode. When there is a packet to be sent and received, it will wake up the port to resume services through the monitoring stream sent regularly to achieve the effect of energy saving.

H3C IE4320 series industrial switches adopt a shallow body with a combo port design, and the power does not exceed 30W under normal working conditions, which is suitable for more scenarios.

IEEE 1588v2 is a master-slave synchronization system. During the synchronization process of the system, the master clock periodically publishes the PTP time synchronization protocol and time information, and the slave clock port receives the time stamp information sent by the master clock port, and the system calculates the master clock accordingly. Slave line time delay and master-slave time difference, and use the time difference to adjust the local time to keep the slave device time

Frequency and phase coincident with master time. IEEE1588v2 can realize frequency synchronization and time synchronization at the same time. The accuracy of time transfer mainly depends on the accuracy of the two condition counters and the symmetry of the link. Compared with traditional timing technology, IEEE1588v2 has obvious advantages. It adopts two-way channel, the precision is ns level, the cost is low, and it can adapt to different access environments and so on. Under the background of the industry that requires increasing precision, IEEE 1588v2 has become an inevitable trend of development.
