Insert up to four Tripp Lite N484-Series copper and/or fiber cassettes (sold separately) into this cost-effective enclosure panel. Mounting in just 1U of space in an EIA-standard 19-inch rack, the compact N484-01U-MINI includes no protruding front door or rear cable management, which allows more inside rack space. It is ideal for a wide range of singlemode and multimode applications in small and medium enterprise environments where equipment is connected in up to three adjacent racks. The fully passive mini panel adds no heat or cooling load.
