Chapter 5 WAVE Interface Modules
Network Adapter Cabling Requirements
Network Adapter Cabling Requirements
Gigabit Ethernet—Copper
The Interface Module 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 5-5 shows the cable requirements for WAVE appliance and non-WAVE appliance connections
when you are using Gigabit Ethernet end to end.
3 Speed — Off No link is detected.
Green On 10 Gigabit Ethernet connection.
Yellow On 1 Gigabit Ethernet connection.
