W&T Ports and indicators
Auto Negotiation: 10/100BaseT, Full/Half Duplex
In its factory default setting the W&T USB-Server uses Auto-
Negotiation mode. To prevent communication problems caused
for example by a duplex mismatch, we recommend also
operating the used port on the switch or hub in Auto-
Negotiation mode. Here both the transmission speed and the
duplex procedure are automatically negotiated and
correspondingly set in the devices.

Managable switches often use special protocols
(Spanning Tree Protocol, Port-Trunking, ...), as needed
for example for uplinks to other switches or the wideband
connection of servers. These protocols are generally not needed
for connecting normal terminal devices such as the USB-Server,
but they may slow down opening of communication
considerably after a restart. We recommend disabling these
protocols and functions on the port used for the USB-Server.
Please consult with your system administrator in this regard.
