HP PoE switch - ports failing

[Stormborn15]

Hi,

I discovered last week that one of our HP PoE switches ( which services, WAP's and telephones) was showing a flashing red fault light and that 3 of the ports had stopped working. Logged the call with HP who logged at logs from the switch and their recommendation is to do a firmware upgrade...

 

1 - how safe is it to do one of these without messing up the entire switch

2 - Please do correct me if I'm wrong - does doing a firmware upgrade sort out faulty ports?

 

 

TIA

It can fix up faults like this yes and usually best to do the upgrade then HP will progress the support request if still no joy, firmware upgrade is safe if performed correctly, dual flash switch procedure is something along the lines of:

 

BACKUP CONFIGS

copy running-config sftp IPOFSFTPSERVER nameoffile.cfg

copy startup-config sftp IPOFSFTPSERVER nameoffile.cfg

 

VIEW FLASH INFORMATION

show flash

 

BACKUP PRIMARY FLASH TO SECONDARY

copy flash flash secondary

 

ALWAYS CHECK CORRECT UPGRADE PATH FOR VERSION THEN PROCEED WITH FIRST UPGRADE

copy sftp flash IPOFSFTPSERVER firmwarename.swi primary

reload

 

CONFIRM SWITCH IS NOW ON DESIRED FIRMWARE

show flash

 

CONTINUE FIRMWARE UPGRADES IF UPGRADE PATH DICTATES

I feel like I'm reading a foreign language here LOL .

Thanks for the reply - my first proper foray into switches .. is it best I try this out of hours?... And will I be ok waiting for half term ie another few weeks ?.. ( but don't want HP to close the call until I'm done... )

Sorry - only just learned how to use PuTTY to telnet into the switch ( helped by HP) that's how green I am about this.. I know I need to get comfortable with this sort of thing ASAP though - so will be doing some sort of switch lab set up if I can...

 

Thanks again :-)

1) With the switch in a known-good state, pretty safe. Even with PoE issues on specific ports, still pretty safe. Just do it when people aren't using the device.

 

2) It depends why the ports are showing as faulty - did they explain their reasoning? Firmware release notes that fix something related, for example?

 

It's more likely that the support rep needs to work through their checklist before they'll let you RMA it.

HP Support will assist in a firmware upgrade if you feel more comfortable with them doing it, just make sure you have backups of the config (They will do this for you) and yes schedule for out of hours.

Brilliant! thanks! :-)

In my experience with HP Support the first thing they have always asked me to do is upgrade the firmware on whatever the device is from a Server to a Switch, they wont assist you any further until you've done so.

We use a lot of hp switches here, I did a firmware upgrade on an HP1820 a few weeks back. If you can go to the IP address of the switch and login via the web interface, my switch had an option to download (and restore) the config.

 

Download config, update firmware worked fine for me. If there was any issues i would have factory reset the switch and then reuploaded my saved config via the web interface.

Thanks - I think if this is possible via the web interface then I would probably feel more confident doing it that way..

Never a dull day in a one man IT team - always learning something new... I'm sure something drops out when something new goes in LOL
