40 Chapter 1 BayStack 420 Switch

Autosensing is used when the attached device is not capable of autonegotiation or is using a form of autonegotiation that is not compatible with the IEEE 802.3u autonegotiation standard. In this case, because it is not possible to sense the duplex mode of the attached device, the BayStack 420 Switch reverts to half-duplex mode.

When autonegotiation-capable devices are attached to the BayStack 420 Switch, the ports negotiate down from 100 Mb/s speed and full-duplex mode until the attached device acknowledges a supported speed and duplex mode.

Autpolarity detects receive and transmit twisted pairs automatically. When autopolarity is active, any straight or crossover category 5 cable can be used to provide connection to a port. If the port is set to a fixed configuration, then autopolarity is not active.

For more information about autosensing and autonegotiation modes, see Chapter 4, “Troubleshooting,” on page 173.
