Firmware upgrade Failure

[weese]

I have a BL p-Class C-GbE2 Interconnect Switch. I'm using the Interconnect Switch Upgrade Tool, ver 3.4.0 to upgrade the firmware. The current version is 2.2.0 and I'm trying to upgrade to 3.2.3. The Tool finds the switch and attempts to upload the firmware but fails. I tried to copy the firmware manually but get an "Image is too large for FLASH region" error message. The boot firmware uploaded ok, just having the problem with the firmware. The specs say the switch has 32M and the boot firmware is ~4M and the firmware is ~4M. Doesn't seem to be a way of checking the amount of memory is available or used.
