Firmware Upgrade

Firmware upgrade is a very important step. Always check if a newer firmware version has been released before

installing new firmware. The development of firmware for HP switches is quite intensive and new versions with

fixes tend to be released relatively often (about every four months). Currently switch firmware is available for

free on a website.

Recommendation:

Always look for new firmware releases for your switches. Always use the newest version available for new

installations if nothing prevents it.

The switch firmware is stored in the switch flash memory. All switches have a primary and a secondary flash

memory. Firmware updates should therefore be done using alternately the primary and secondary flash

memory. With this procedure you will always be able to return to the previous version in case of any

unexpected problems.

Recommendation:

Use primary and secondary flash memory alternately to update the switch firmware.

The following example assumes that the firmware is stored on your TFTP server and that the TFTP server is

accessible through the IP protocol from the switch. In this example the TFTP server address is 10.229.255.15

and the firmware is stored in the file hp-img/hp54xx/K_14_41.swi .

We list the flash memory contents

hp-test# show flash

Image Size(Bytes) Date Version

----- ---------- -------- -------

Primary Image : 9798890 08/27/09 K.14.19

Secondary Image : 7544081 02/26/09 K.13.58

Boot Rom Version: K.12.20

Default Boot : Primary

We verify the TFTP server accessibility

hp-test# ping 147.229.255.15

147.229.255.15 is alive, time = 1 ms

The image is now loaded into the secondary flash - confirm the operation by pressing the "y" key. The whole

operation takes a few minutes.

hp-test# copy tftp flash 147.229.255.15 hp-img/hp54xx/K_14_41.swi secondary

The Secondary OS Image will be deleted, continue [y/n]? y
