Black Box Extreme Media Converter Switch - fiber media converter - 10Mb LAN

Convenient and compact networking device with Plug-and-play installation. The robust metal case protects circuitry and communications from the demands of industrial applications. No internal airflow required for cooling. The convection case works as a heat sink. Resists dirt debris smoke insects and moisture (IEC529 IP40 rated). Designed for NEBS compliance to withstand shock vibration and high altitudes. Copper ports auto-negotiate to network and device speeds. Autocross (MDI-X) on the copper side. Cascade easily without the need for a crossover cable. Provides full 10- 100- and 1000-Mbps switching for high-performance LANs. Supports VLANs. Retrieves and transmits 802.1q tagged data packets unchanged. Use store-and-forward type switching to eliminate bad packet propagation and maximize bandwidth. Dynamically allocates buffer space minimizing the dropping of frames on congested ports. Collision-based flow control (half-duplex mode only) stops frames from entering when buffer queue space is low. Internal addre
