I have an older Altas 550 with current firmware "ATLAS 550 Rev. B.02 10/05/00 13:07:09"
I am trying to update so it will allow a Quad T1 module (PN: 1200755L1).
When I attempt to start the update I get the error "no valid slots are available".
It is not even attempting to connect to the TFTP server.
PLEASE help.
