Fan-less design
The DIS-300G Series Industrial Gigabit Managed Switches are designed specically to
withstand wide temperature range, vibrations and shock. These rugged, yet easy to deploy,
switches have superior environmental specication compared to those of commercial network
switches. With its hardened design combined with high availability network features, these
switches form vital parts of any network infrastructure facilitating the increasing demand for
smart cities, city-wide surveillance and wireless connectivity.
With its comprehensive feature set, DIS-300G managed switches are easy to congure, partition and
organise user’s network and provide reliable and quality of service. The DIS-300G-8PSW and DIS-
300G-14SPW switches are PoE switches which are compliant with both IEEE 802.3af and IEEE 802.3at
PoE standards and delivering up to 30 watts power per port along with data on standard Ethernet
cabling. These switches can be used to power any IEEE 802.3af/at compliant PoE PD devices, which
eliminates the need for additional wiring. They also provide additional PoE power management
features which can greatly reduce the deployment eort of planning PoE power budget.
Customers
The DIS-300G Series family of switches is ideal for customers looking for cost-eective and
customisable networking solutions with redundancy and security, designed for industrial
environments.
