Software Upgrade

When you upgrade software through TFTP, you need to upload the upgrade file on the TFTP server to the switch. After upgrade, the system restarts and uses the loaded file.

Context

The Trivial File Transfer Protocol (TFTP) is a file transfer protocol.

The TFTP client supports file upload and download by using TFTP. TFTP uses the User Datagram Protocol (UDP) to transmit files, simplifying the transmission process.

CAUTION:

• Ensure that configurations are saved before upgrading software.
• Do not power off the switch during the upgrade.
• Software upgrade requires a long time; therefore, before upgrading the software, choose System Management > System Configuration > System Settings and set Http Timeout Interval to 50 minutes or a greater value.

Procedure

1. Choose System Management > Software Upgrade in the navigation tree to open the Software Upgrade page.
   Table 1 describes the parameters on the Software Upgrade page.
