    GS108T Smart Switch Software Administration Manual Figure C-3 Note: Flat “silver satin” telephone cable might have the same RJ-45 plug. However, using telephone cable results in excessive collisions, causing the attached port to be partitioned or disconnected from the network. Using 1000BASE-T Gigabit Ethernet over Category 5 Cable When you use the new 1000BASE-T standard, you must consider the limitations of cable installations and the steps necessary to ensure optimum performance.
  • Page 133: Length

    GS108T Smart Switch Software Administration Manual If installing new cable, NETGEAR recommends using Category 5e cable, since it costs about the same as Category 5 cable. If using the existing cable, be sure to have the cable plant tested by a professional who can verify that it meets or exceeds either ANSI/EIA/TIA-568-A:1995 or ISO/ IEC 11801:1995 Category 5 specifications.
