I have an IP Office 403 (SW 3.2(61)) with a DS 30 expansion module that just stopped working. All I did was swap a couple of extensions physically from the DS30 and the control unit. Tech support helped me DTE the DS30 and it says TFTP poll sent but will not grab it's software/firmware and boot up. I have the TFTP server defined (the VMpro PC) and manager open. It's like there is no communication between the DS30 and the control unit. Suggestions?
