Upgrading MGC/MGX LW

Problem Clarification:

When adding a new MGC/MGXpec to a CS1000E PBX system, the card boots up and attempts to upgrade it's 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 is due to 'Secure Transfer' mode being set. It is necessary to disable secure transfers to enable the card to update.

Solution:

1 Unreg CS and MGC from UCM Security domain...

LD 117:
=> unreg u dev <ip>             where <ip> is the MGC/MGX failing to upgrade

2 Disable secure transfer...

LD 117:
=> dis transfers secure         disable secure transfers

3 Upgrade the loadware through LD 143...

LD 143:
.upgmg all seq                  'upgmg stat' to check upgrade progress

4 Reregister the MGC/CS to security domain...

LD 117:
=> enl transfers sec            re-enable secure transfers
=> reg u dev <ip>               re-register the MGC/MGX device <ip>
