What type of cables do I use to connect my ProxyAV appliance to Cisco products?
If the ProxyAV (2000-E) is connected to a Cisco router, you must use a cross-over cable if the Ethernet Media Link Speed is set to anything but Auto Negotiate. Although a patch cable works with Auto Negotiating, Blue Coat recommends using a cross-over cable if the ProxyAV is connected to a Cisco router to avoid conflicts with the differing behavior. If you are using a Cisco switch, a patch cable can be used.
