Inline Network Adapter Cabling Requirements
Your inline network adapter ships with two types of cables: crossover and 
straight-through. When you connect the WAE inline network adapter, proper 
cabling depends on the link speed (Gigabit Ethernet or Fast Ethernet) and the 
types of devices (DCE or DTE) being connected. 
Note
You must retain the same link speed from one end of the connection to the other 
end. Inline adapter interfaces are able to autonegotiate link speeds. If any of your 
connecting interfaces are configured for Fast Ethernet (whether on a switch or a 
router), your WAE inline adapter uses Fast Ethernet. If any of your connecting 
interfaces are configured for Gigabit Ethernet, your WAE inline adapter uses 
Gigabit Ethernet. Speed and duplex settings are port-specific, so two inline ports 
can negotiate different speeds independently.
If you are connecting a WAE inline appliance between two devices using Gigabit 
Ethernet, you can use either straight-through cables, crossover cables, or any 
combination of the two cable types, regardless of the type of device. However, for 
consistency, we recommend that you use straight-through cables for all Gigabit 
Ethernet connections.

you are using Gigabit Ethernet end to end.
