Thanks shalvors. I know that GigE requires all 4 pairs, and that 10/100/1000 hardware should throttle down to 100 BaseT if only 2 pairs are present. I was wondering if anyone has experienced or heard of dropped connection issues when running GigE hardware on 2 pair 100 BaseT.

I am troubleshooting a server to clients connectivity issue. I have changed all patch cords and swapped the rj45 jacks. I have not tried installing a new NIC in the server as of yet. However, I did discover today that the cat5 cables at the 12 port patch panel only have the orange and green pairs punched down as per 100 base tx. I wonder if anyone has run into any intermittent connectivity issues when running Gig E on only 2 pair 100 base tx.

10/100/1000 ethernet over 2 pair wiring

Networking hardware includes the physical devices facilitating the use of a computer network. Typically, networking hardware includes gateways, routers, network bridges, modems, wireless access points, networking cables, line drivers, switches, hubs, and repeaters. But it also includes hybrid network devices such as multilayer switches, protocol converters, bridge routers, proxy servers, firewalls, network address translators, multiplexers, network interface controllers, wireless network interface controllers, ISDN terminal adapters and other related hardware.

Networking Hardware-Other

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.

Networking

A switch is a device that filters and forwards packets of data between LAN segments. Switches operate at the data link layer or the network layer of the Open Systems Interconnection (OSI) Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. A hub is a connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports; when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.
