7.5 Loading a Host Software Containing the Boot ROM File
The S7502 supports multiple types of cards and these cards use different versions of
Boot ROM. Thus, you are required to use the correct Boot ROM file when upgrading the
Boot ROM of a card. The upgrading fails if the Boot ROM file does not match the card.
To avoid the inconvenience caused by different Boot ROM files in upgrading, Boot
ROM files are combined into a host software file. That is, you can use this combined file
for on-line upgrade of all cards.
A Boot ROM file is named as “*.btm”, while a host software file containing the Boot
ROM file is named as “*.app”.
7.5.1 Example of Upgrading Using Combined Host Software File
I. Preset conditions
z
The SRPU in slot 0 of the S7502 is LS81P12TE.
z
The LPU in slot 1 is LS81FT48A.
z
The host software containing the Boot ROM file is S7502.app.
z
Both online upgrading through command line and upgrading through Boot Menu
use FTP mode.
Step 1: Download the host software that supports the combined Boot ROM file to the
switch through FTP.
<H3C> ftp 10.10.110.1
[ftp] get S7502.app
[ftp] bye
Step 2: Specify S7502.app as the application software used by the switch for the next
boot.
<H3C> boot boot-loader primary S7502.app
Step 3: Reboot the switch to make the S7502.app effective.
<H3C> reboot
