Software Maintenance

Software Maintenance Overview

Software maintenance of a switch means to upgrade the switch host software and Boot ROM through
the host software package, which contains the host software and the Boot ROM program, and is with
the extension name of .app (S7500E.app for example).
Host software upgrade involves downloading the host software package onto the Flash of both the
active and standby SRPUs, and setting the main and backup boot files.
Boot ROM upgrade involves upgrading the Boot ROM of the SRPUs and LPUs through the Boot
ROM program in the host software package.
There are two ways to upgrade host software and Boot ROM programs:
Upgrade through boot menu.
Upgrade through command lines.
However, you can upgrade the Boot ROM program of LPUs through command lines only.
To ensure the software version consistency between the active and standby SRPUs, upgrade the
software in the same way, that is, upgrade the software on both the active and standby SRPUs
either through command lines or through the boot menu.
Since upgrading through command lines affects the services of the S7500E series less significantly
than upgrading through the boot menu, the former is recommended.

Upgrading Through the Boot Menu

You can download the host software package onto the Flash of a switch in one of the following ways:
Download through a management/upgrade Ethernet port using TFTP
Download through a management/upgrade Ethernet port using FTP
Download through the console port using XMODEM
After downloading the host software package onto the Flash, specify the main/backup boot file to
complete the host software upgrade. If you need to upgrade the Boot ROM of the SRPUs through the
boot menu, refer to section "Updating Boot ROM Through a File on the Flash" on page 6-12.

displayed on the terminal:
