ICP 3300 Software Upgrade using Software Installer question
« on: March 02, 2016, 03:31:06 PM »
Hello everyone!

We've been upgrading our 3300 ICP systems using the software installer.  One system is already at "Activate New Software (includes system reset)  = Pending" state just waiting for "Start" to be pressed.

However, plans changed and I was told I cannot have ANY phone outages.

If someone reboots the 3300, or a power outage happens, will the new software get loaded? Thanks for the confirmation.

Yes, if it's already at this state, then a reboot will trigger it.

This is what resiliency is for. You can have a backup 3300 for the phones to fail over to while you apply the software update to the primary. Although in practice, I like to upgrade the secondary first, then the primary.

This of course requires the secondary controller to have it's own access to PSTN trunking, however.

No offense, but how does this help the issue of being down well all the phones flash firmware? When they either fail to the upgraded secondary, or reconnect to the upgraded controller, they will flash immediately. I think from the first post, that was the real issue.

Thanks everyone for your replies!

We do have resiliency including ISDN (via resilient framer), but in almost all setup, both systems are in the same power source.  This system that's ready for activation, happen to host over 200 users. 

With just 100 users, I've seen the phones download the flash firmware twice, then take close to 5 minutes for the download.

So yes, it will be an outage which management won't agree on  :).
