Tripp Lite's DNET1 offers network ethernet line surge suppression for 100Base-T, 10Base-T, Token Ring, AS400 / Sys3x and RS422 applications. Convenient RJ45 input and output connections with included 5 inch ethernet patch cable allows convenient placement at the protected device network connection. Surge suppression is handled with balanced arrays of high-speed avalanche diodes that divert excess energies created by electrostatic discharges, faulty wiring or lightning away from network interface connections. Tripp Lite network surge suppressors reduce blown NIC cards, garbled network transmissions, system lock-ups and hard equipment failure by safely shunting dataline surges to ground. Six inch heavy guage grounding lead connects to designated grounding lugs available on the back panel of most network workstations and pieces of internetworking equipment. Lifetime warranty
