Troubleshooting Table J-4: Troubleshooting: Upgrading Firmware Using the Serial Port Problem On the serial console screen, a message that GbE Interconnect Switch failed to load runtime image (firmware) is displayed. From the serial console, pressing the pound (#) key during the boot procedure does not force the GbE Interconnect Switch into the download mode. After forcing the GbE Interconnect Switch into the download mode, the console screen displays a message to change the baud rate for your terminal emulation session for ZModem transfer and also displays unusual characters. After starting to download the firmware file, the download fails. The GbE Interconnect Switch configuration is corrupt. Possible Cause The Runtime image (firmware file) is corrupt. The Flash file system is partially corrupted. You did not press the pound (#) key during the time the boot procedure responds to this special key. Your terminal emulation session baud rate does not match the GbE Interconnect Switch serial console baud rate in the download mode. The firmware file is not the correct one or is corrupt. An error was made when saving the GbE Interconnect Switch configuration. Possible Solution Download the new runtime image (firmware file) using the procedure in Appendix G. Call your service representative. Press the pound (#) key immediately when you see the boot procedure starting the Power-On SelfTest. Pressing the pound (#) key in the middle of the Power-On Self-Test process puts the GbE Interconnect Switch into the download mode instead of the runtime mode. Change the baud rate of your terminal emulation session to match the GbE Interconnect Switch serial console baud rate in the download mode. IMPORTANT: The baud rate for the GbE Interconnect Switch serial console in the download mode and runtime mode are two separate settings. Obtain the latest firmware file that is specified for this GbE Interconnect Switch. Reboot the GbE Interconnect Switch and reload the factory settings. This action clears all settings and restores them to the initial values that were present when the GbE Interconnect Switch was purchased. Refer to the management interface reference guides for more information. After reloading the factory settings, reconfigure the GbE Interconnect Switch settings. IMPORTANT: When rebooting, you have the option to reset all settings except the IP address.

Table J-4:

Troubleshooting: Upgrading Firmware Using the Serial Port

Problem

Possible Cause

Possible Solution

The Runtime image (firmware

file) is corrupt.

Download the new runtime image (firmware file)

using the procedure in Appendix G.

On the serial console

screen, a message that

GbE Interconnect Switch

failed to load runtime

image (firmware) is

displayed.

The Flash file system is partially

corrupted.

Call your service representative.

From the serial console,

pressing the pound (

) key

during the boot procedure

does not force the GbE

Interconnect Switch into

the download mode.

You did not press the pound (

)

key during the time the boot

procedure responds to this

special key.

Press the pound (

) key immediately when you see

the boot procedure starting the Power-On Self-

Test. Pressing the pound (

) key in the middle of

the Power-On Self-Test process puts the GbE

Interconnect Switch into the download mode

instead of the runtime mode.

After forcing the GbE

Interconnect Switch into

the download mode, the

console screen displays a

message to change the

baud rate for your terminal

emulation session for

ZModem transfer and also

displays unusual

characters.

Your terminal emulation session

baud rate does not match the

GbE Interconnect Switch serial

console baud rate in the

download mode.

Change the baud rate of your terminal emulation

session to match the GbE Interconnect Switch

serial console baud rate in the download mode.

IMPORTANT:

The baud rate for the GbE

Interconnect Switch serial console in the download

mode and runtime mode are two separate settings.

After starting to download

the firmware file, the

download fails.

The firmware file is not the

correct one or is corrupt.

Obtain the latest firmware file that is specified for

this GbE Interconnect Switch.

The GbE Interconnect

Switch configuration is

corrupt.

An error was made when saving

the GbE Interconnect Switch

configuration.

Reboot the GbE Interconnect Switch and reload the

factory settings. This action clears all settings and

restores them to the initial values that were present

when the GbE Interconnect Switch was purchased.

Refer to the management interface reference

guides for more information.

After reloading the factory settings, reconfigure the

GbE Interconnect Switch settings.

IMPORTANT:

When rebooting, you have the option

to reset all settings except the IP address.
