1.1.7 Console Port is Not Responding
The WS5000 Series Switch console port is physically connected to the host computer’s serial port, but pressing
the [Enter] key gets no response from the switch. Table 1.6 provides suggestions to troubleshoot this issue.
1.1.8 WS5000 CLI Prompt Displays DIAG>
The WS5000 Series Switch changes into the diagnostics mode, displaying the DIAG> prompt, when it
encounters a critical internal failure, such as when the switch is unable to start. This is a fatal error that should
never happen.
From the DIAG> prompt, the following options are available:
•reset
• shutdown
• restore
Before contacting the Symbol Support Center, perform the following suggested corrective actions:
1. From the DIAG> prompt, invoke the reset command.
DIAG> reset
This command resets the system.
2. From the DIAG> prompt, invoke the restore default configuration command:
DIAG> restore <default config>.cfg
3. From the DIAG> prompt, invoke the restore system image command. Restore a known good image, not
the image used when the switch went into diagnostics mode.
DIAG> restore WS5000_x.x.x.0-00xx.sys.img
