To reset the switch, use the Tools> Reset command or remove AC power from the switch and then reapply AC power. If the problem continues, contact NETGEAR technical support. In North America, call 1-888-NETGEAR. If you are outside of North America, please refer to the support information card included with your product. -

• A ‘U’ for a given port and VLAN will mean that packets leaving the switch from that port and VLAN will be Untagged. Inversely, a ‘T’ for a given port and VLAN will mean that packets leaving the switch from that port and VLAN will be tagged with the respective VLAN ID in which it participated in. - Page 94 Two examples of for setting up VLANs will be given. Example 1 will step through a simple two-group VLAN setup. Example 2 will step through a more elaborate setup illustrating all possible scenarios for a comprehensive understanding of tagged VLANs. Example 1 This example shows the basics of setting up a VLAN.
- Page 95 In the VLAN Membership page, use the space bar to modify the matrix until the desired ports are all members of the selected VLAN as either tagged or untagged ports. Page 94 of 105...
- Page 96 To allow untagged packets to participate in the ‘First’ VLAN, make sure to change the Port VLAN IDs for the relevant ports. Access the PVID Settings page then use the space bar to add an ‘X’ indicating which Port VLAN ID is assigned to which port. Page 95 of 105...
- Page 97 Example 2 This example demonstrates several scenarios of VLAN use and how the switch will handle VLAN and non-VLAN traffic. Setup the following VLANs: Configure the VLAN membership. Each image below shows a different VLAN to be setup. Be sure to set all of them as follows.

APPENDIX E: CONNECTOR PIN ASSIGNMENTS This appendix provides information about the RJ-45 plug and the RJ-45 connector used for the NETGEAR Model GSM712 Managed Gigabit Switch. RJ-45 Plug and RJ-45 Connector In a Fast Ethernet network, it is important that all 100BASE-T certified Category 5 cabling use RJ-45 plugs. The RJ-45 plug accepts 4-pair UTP or shielded twisted-pair (STP) 100-ohm cable and connects into the RJ-45 connector. -

APPENDIX F: CABLING GUIDELINES This appendix provides specifications for cables used with the NETGEAR Model GSM712 Managed Gigabit Switch. Fast Ethernet Cable Guidelines Fast Ethernet uses UTP cable, as specified in the IEEE 802.3u standard for 100BASE-TX.The specification requires Category 5 UTP cable consisting of either two-pair or four-pair twisted insulated copper conductors bound in a single plastic sheath. -
Page 105: Figure F-1. Straight-Through Twisted-Pair Cable
Patch Panels and Cables If you are using patch panels, make sure that they meet the 100BASE-TX requirements. NETGEAR recommends Category 5 UTP cable for all patch cables and work area cables to ensure that your UTP patch cable rating meets or exceeds the distribution cable rating. - Page 106 Cabling The 1000BASE-T product is designed to operate over Category 5 cabling. To further enhance the operation, the cabling standards have been amended. The latest standard is Category 5e, which defines a higher level of link performance than is available with Category 5 cable. If installing new cable, we recommend using Category 5e cable, since it costs about the same as Category 5 cable.
