IP Handset 5320 upgrade failure

[Atkins80]

Hi all

I've just upgraded a CX3300II system to Ver 7, I've started to connect the IP handsets and out of 30 the first 15 of them upgraded no problem, the rest now get stuck in a loop, they connect to the TFTP start to download and all of them get to the same point in the download procedure (1380) then reboot and end up going around in a loop, I've tried a factory reset on the handsets, rebooted the system, I've tried plugging a handset directly in to the Lan port to eliminate any network issues. I'm thinking that something may have got corrupted with the file required? have you seen this before or have any ideas if theirs an easy fix? I'm starting to look at the option of having to reload the software from scratch which i would like to avoid!!

Cheers Atkins80

are they 53xxe phones

there is a bug with some of the handsets and they will need to be rerplaced if they have faulty chips

under the module the large chip should NOT say EM639 at the start ( bad chip 16M ram instead of 32M)

if it says EM63A its good

If I never did anything I'd never done before , I'd never do anything.....

Yeh there 5320e model. That would make sense as to why they get to a certain point and then fail if the chip doesn't have enough ram. cheers for the info i'll have a look at the handsets tomorrow

Thanks!!!
