Upgrading MGC/MGX LW

Problem Clarification

When adding a new MGC/MGXpec to a CS1000E PBX system, the card boots up and attempts an upgrade its loadware.
Once it starts, it fails with the following error:

SRPT063 IPMG 0 0: Failed to retrieve [/u/ipmg/mgc/dnldlist.rec] in 3 tries.Upgrade failed.

Cause

File mgcinfo.rec/dnldlist.rec cannot be transferred from Call Server to MGC. Problem due to "secure transfer" mode.
