Using the BayStack 350 Series 10/100 Autosense Switch
4-6
893-00992-E
In both situations, the BayStack 350 switch “autosenses” the speed of the
connected station and, by default, reverts to half-duplex mode. If the connected
station is operating in full-duplex mode, it cannot communicate with the switch.
To correct this mode mismatch problem, follow these steps:
1.
Use the Port Configuration screen to disable autonegotiation for the
suspect port (see “Port Configuration” on page 3-36).
2.
Manually set the Speed/Duplex field to match the speed/duplex mode of
the connected station (see Table 3-13 on page 3-37).
You may have to try several settings before you find the correct speed/duplex
mode of the connected station.
If the problem persists, follow these additional steps:
1.
Disable the autonegotiation feature at the connected station.
2.
Manually set the speed/duplex mode of the connected station to the same
speed/duplex mode you have manually set for the BayStack 350 switch
port.
Port Interface
Ensure that the devices are connected using the appropriate crossover or
straight-through cable (see Appendix C, “Connectors and Pin Assignments”).
Note:
Nortel Networks recommends that you manually set the BayStack 350
switch port to the desired speed/duplex mode when connecting to any of the
following Nortel Networks products:
• Nortel Networks 28000 product family
• Nortel Networks 58000 product family
• BayStack Model 302T switch (100 Mb/s port)
