Inline Network Adapter Cabling Requirements
The inline network adapter ships with two types of cables: crossover and
straight-through. When you connect the WAVE inline network adapter, the cable
that you use 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 you
configure any of your connecting interfaces for Fast Ethernet (whether on a switch
or a router), your WAVE inline adapter uses Fast Ethernet. If you configure any
of your connecting interfaces for Gigabit Ethernet, your WAVE inline adapter
uses Gigabit Ethernet. Speed and duplex settings are port specific so that two
inline ports can negotiate different speeds independently.
If you are connecting a WAVE 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.
Table 4-2
shows the cable requirements for WAVE appliance and non-WAVE
appliance connections when you are using Gigabit Ethernet end to end.
