5324 Checksum error

[OldMatey]

Hey,

I am getting checksum errors on 5324's after they download new firmware.

The current firmware is 2.0.0.31 and I have ftp'd the 2.0.2.2 firmware to the 3300.

here is how the phone boot up goes.

plug in gets vlan / pri info fine.

uses option 125 and gets DHCP address.

does "downloading" up to 1470 (which is what it should go up to for the new firmware) then says checksum error and reboots.

Any ideas?

This has only just started happening. In previous days the same type of phone on the same platform with same new firmware (2.0.2.2) have been working fine. I have tried different phones, ports, cables etc.

Thanks
