Autodisabled Ports

The Express 130T Standalone Hub automatically disables a port when it detects a serious error on that port, such as a series of more than 64 collisions on a single packet. Once the hub sees a valid packet from the device or is able to transmit a packet from the port, it automatically reenables the port. Connected devices aren’t usually affected by an autodisabled port because the port is reenabled so quickly.

If a port remains autodisabled, check the connected device’s network adapter and cabling, or unplug the network cable for a few seconds, then reattach it.
