The D-Link DGS-1216T is housed in a new style 19” rackmount case with an easy-to-view front panel and diagnostic LEDs and feature an innovative fanless design to ensure quiet operation compared to standard switches.Has 16 10/100/1000BASE-T Auto-negotiating, Auto-MDI/MDI-X ports with 802.3x Flow Control.

Some friends asked why won’t Gigabit connection get a link?

I find the answer on the dlink website : www.dlink.com

A common problem when connecting different gigabit devices is Auto-sensing between the two different ports. When connecting two Gigabit devices it is imperative that the port speed be set the same on both sides. Some Managed Gigabit products have the ability to have the port speed set at either 1000Mbps/Full duplex or Auto. Other Un-Managed products don’t have the ability to modify the port speed at all. If you are using an Unmanaged device, or a device that doesn’t have the ability to set the port speed at 1000Mbps/Full duplex, you may not be able to connect to a device whose port speed is set to 1000Mbps/Full duplex.

When useing D-Link DGS-1016D switch,if the link speed is not 1.0 Gbps, than the cabling between the two endpoints should be examined. If using Gigabit over Copper (1000 Base-T) than you can use Ethernet cable Cat 5 or better (Cat5E, Cat6 or Cat6E). If the cable is pinned improperly, than the network connection will not run at gigabit speeds. Gigabit over copper uses all 8 wires of the Ethernet cable.

If you are using a store bought/factory pinned cable, and the connection speed is still not connecting at 1.0 Gbps, there may be a bent/broken pin on either the NIC, or the switch port. Isolate each portion of the possible problem, until you are able to find the defective port on the network. This can be done by using known good gigabit ports, and cabling.
