After the switch writes a core dump file or other debug information to the storage device, and before you can view the contents on the device, you must ensure it is safe to remove the device from the switch. Use the eject usb-device command to prepare the device for removal. After you run the eject usb-device command, you can manually remove the storage device from the switch and read the data on the device.
To access and read the data on a removable storage device, use a PC with the appropriate hardware, such as a compact flash reader/writer and follow the manufacturer‘s instructions to access the compact flash card and read the data.
