Status Mode Button and LEDs
The status mode button is used to select the corresponding status indicated by the port status LEDs. Each press of the status mode
button selects the next mode in the following sequence.
1.
STAT: Port LEDs indicate link and traffic activity (the default mode).
2.
SPD: Port LEDs indicate the link speed.
3.
ID: Port LEDs indicate the stack unit ID when the switch is in stacking mode, or the PE ID when in SPX mode.
4.
USB: Indicates files are being copied to a USB drive connected to the USB port.
When in USB mode, pressing the status mode button for 5 seconds copies files, such as FastIron image and manifest files, configuration
files, and Show Tech (supportsave) files from the switch to the USB drive. This capability must be enabled by using the
reverse-manifest
enable
command in the CLI.
The switch system automatically copies files from an inserted USB drive to the system flash after a system reload. The USB drive must
have the files preloaded. The status mode automatically selects USB mode when a USB auto-copy begins.
The following table describes the USB status mode LED for a file copy to or from a USB drive.
