The wiring configuration of the port is set automatically with automatic
MDIX detection. You may not disable automatic MDIX detection. For
automatic MDIX detection to work successfully, the network device you
connect to the port must also support the feature. If it does not, the NET
MGMT port defaults to MDIX. This may entail the use of a crossover cable.
Here are the guidelines to choosing a straight-through or crossover cable
for the port:
 You may use a straight-through cable to connect the port to a
network device that operates at 1000 Mbps.
 You may use a straight-through or crossover cable to connect the
port to a network device that supports automatic MDIX detection
and that operates at 10 or 100 Mbps.
 You must use a straight-through cable to connect the port to a
network device that operates at 10 or 100 Mbps and has a fixed
wiring configuration of MDI.
 You must use a crossover cable to connect the port to a network
device that operates at 10 or 100 Mbps and has a fixed wiring
configuration of MDIX.
After cabling the ports in the chassis, go to Chapter 9, “Powering On the
Chassis” on page 173.
