The IDS-305F is a 5 port Managed Ethernet Switch that can operate in industrial environments providing advanced performance and enabling real-time deterministic network operation. Four 10/100/1000-Base-T Ethernet ports are available for networking Gigabit and Fast Ethernet devices. One 100Base-X fiber connection is available to extend Fast Ethernet operating distances over fiber. In industrial plants, where high levels of electromagnetic interference ( EMI ) is a common phenomenon, utilizing fiber is critical. EMI can cause data corruption over copper-based Ethernet links. However, data transmitted over fiber optic cable is completely immune to this type of noise ensuring optimal data transmission across the plant floor. Perle Industrial-grade Ethernet Switches are designed to stand up to extreme temperatures, surges, vibrations, and shocks found in industrial automation, government, military, oil and gas, mining and outdoor applications. With over 28 models, the Perle IDS-305F offers a choice of connectors, fiber types, temperature support and operating distances. The simple Plug and Play installation available in Perle's Fast Setup feature gets your Ethernet devices networked immediately. The familiar Command Line Interface9 (CLI ), via in-band Telnet or the out-band serial console port,will be appreciated by CCNA ( Cisco Certified Network Associate ) and CCNP ( Cisco Certified Network Professional ) trained engineers.
