To connect the inline network adapter using the correct cables for Fast Ethernet
connections, follow these steps:
Step 1
Determine the type of cable that you would use for a direct connection between
your two end devices (without a WAVE inline network appliance connected
between them) by using the following standard cabling rules:
•
When you are directly connecting two network devices that are similar, such
as two switches, use a crossover cable.
• When you are directly connecting two network devices that are different, such
as a switch and router, use a straight-through cable.
Note
Because the inline network adapter has an internal crossover connection
that becomes active when the InlineGroup interface is placed in
mechanical bypass mode, you must decide which cable you would use to
connect the two network devices directly, and then you must install the
other cable type (on one side, usually the WAN side of the inline
appliance) instead.
Table 5-3 shows the cable requirements for WAVE and non-WAVE connections
when you are using Fast Ethernet end to end.
