Some of you may know I’m an IT Manager by day. We post very few tech articles although our “How to Defrag in Windows Vista” article is our most popular, sometimes accounting for 75% of all traffic. I came across a fairly major problem with some HP Procurve switches the other day and found very little help on the Internet. This article is basically just to get a solution on the web so it may help other IT Managers.
If you read our blog mainly for our food and wine then this is probably of no interest and you can ignore it!
I recently bought a few new HP Procurve 2510G-24 switches. I found that when connecting a server or PC the machine was unpingable for about 4 or 5 minutes. After this time the machine was fully contactable.
Nothing I tried seemed to help and there didn’t seem to be an obvious setting to change in the web config. Any hardware plugged into the switch was unresponsive for ~4 minutes.
Firmware upgrade! Our switches (bought July 2009) were shipped with firmware Y.11.01 (May 2008) even though the latest firmware Y.11.08 came out October 2008. Just go to the HP Switch download page and get the latest version.
Installing Firmware on 2510G
The way I installed the firmware was as follows:
- Install Solarwinds free TFTP server. (On a Vista machine, make sure the service is started via the Admin Tools Services app, not the software).
- Drop the Y_11_08.swi file in the c:\TFTP-Root folder.
- Use the console cable to connect a laptop to the switch.
- Connect to the switch, I used PuTTY.
- Run the command:
copy tftp flash (ip address of TFTP server) Y_11_08.swi
- Give it time to run.
- After it has finished a “show ver” will still show the old firmware. Run the command “boot” to reboot to the new firmware.
After the reboot the 4-5 minute problem disappeared. Good luck!
