Auto-MDIX
Note that some newer PCs and IP Switches feature "Auto-MDIX" Ethernet connectors. These Ethernet
connections will automatically sense the direction of the connection and do not require cross-over cables.
IP Switch Configuration – Speed & HDX/FDX Negotiation
Some IP Switches (like some HP Pro-Curve Switches) that have Auto Speed and Duplex negation may not be
able to auto-negotiate with the HIB-IP unit. This may cause the HIB-IPs units (and their connected MCN
modules to cycle off-line and on-line in the MCN software.
In those cases, we recommend that you manually configure the Ethernet port in the IP switch that connects to
the HIB-IP.
Manual Configuration:
Speed: 10 Mbits/sec
Duplex HDX
