If the problem persists:
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 450 switch
port.
Port Interface
Ensure that the devices are connected using the appropriate crossover or
straight-through cable (see
Appendix F, “Connectors and Pin Assignments”).
Software Download Error Codes
Table 4-3 describes error codes that are associated with the software download
process. The error codes appear only on the console screen of the switch that is
connected to your TFTP load host during the software download process.
If an error code appears during the download process, perform the appropriate
corrective action provided in
Table 4-3. If the suggested corrective action does not
resolve the problem, contact your Nortel Networks Technical Solutions Center
(see
“How to Get Help” in the Preface section of this guide).
Note: Nortel Networks recommends that you manually set the BayStack 450
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)
