Hub, switch, Patch Panel Problem

Hub, switch, Patch Panel Problem

Hub, switch, Patch Panel Problem

I have a problem with a ssegment of my net work where I have a switch from the backbone whci hfeeds to a hub then to a patch panel.  Some of my drops do not work through the hub but work OK when directly through the switch.  I replaced the hub with a new hub and same thing.  Any ideas?

RE: Hub, switch, Patch Panel Problem

The Switch is full duplex, or can be, the hub MUST be half duplex.  If your end devices are hard coded to be full duplex, they will only work in the switch.

I tried to remain child-like, all I acheived was childish.

RE: Hub, switch, Patch Panel Problem

If it work fine without the patch panel, suspect the PATCH PANEL!

RE: Hub, switch, Patch Panel Problem

He didn't say that it worked without the patch panel. He said it worked with a SWITCH and not a HUB!!

shot in the dark,... have you verified/ mapped the cable pair pinout of each port off of the patch panel to its opposite end.  Ensure that there are no opens or incorrect wiring, e.g. 568A on one end, 568B on the other, etc.


RE: Hub, switch, Patch Panel Problem

Jimbopalmer has already hit the nail on the head. If the drops work with the switch then the wiring is correct. The problem is with the half duplex nature of the hub.
