Software Download This section contains instructions for downloading device software (system and boot images) through a TFTP server or USB port. The TFTP server must be configured before downloading the software. Software Auto Synch in Stack When several units are stacked, they must all run the same software version. When a new slave device is inserted into the stack, it is first checked for compatibility (meaning that the master can run firmware upgrade/downgrade to the slave unit), and if found compatible, its boot and image software versions are automatically updated with the Master's. If the slave is found not compatible, it is shutdown. A SYSLOG message is sent when a master synchronizes a slave's software. System Image Download When the device boots, it decompresses the system image from the flash memory area and runs it. When a new image is downloaded, it is saved in the other area allocated for the other system image copy. On the next boot, the device decompresses and runs the image from the currently active system image. A system image can be downloaded through a USB port or a TFTP server. To download the system image from a TFTP server, ensure that an IP address is configured on one of the device ports and pings can be sent to the TFTP server. In addition, ensure that the file to be downloaded is saved on the TFTP server. To download a system image through the USB port or TFTP server: 1 Enter the show version command, to verify which software version is currently running on the device.
