The MDI/MDIX wiring configuration of the ports is set automatically with
automatic MDIX detection. You may not disable this feature on the ports.
For automatic MDIX detection to work successfully, the remote device
connected to a port must also support the feature. If it does not, a port on a
line card defaults to MDIX. This may require the use of a crossover cable.
Here are the guidelines to choosing straight-through or crossover cabling
for the ports:
 You may use straight-through cables on ports that are connected
to network devices that operate at 1000 Mbps.
 You may use straight-through or crossover cables on ports that are
connected to network devices that support automatic MDIX
detection and that operate at 10 or 100 Mbps.
 You must use straight-through cables on ports that are connected
to network devices that have a fixed wiring configuration of MDI
and that operate at 10 or 100 Mbps.
 You must use crossover cables on ports that are connected to
network devices that have a fixed wiring configuration of MDIX and
that operate at 10 or 100 Mbps.

the bottom role, orient the connector with the release tab on the
bottom. Refer to Figure 86 on page 134.
 To remove a cable from a port, pull gently on the release tab and slide
the cable connector from the port.
