Establishing a Sequence for Downloading Software onto Each GQAM
The order in which you download new software onto GQAMs allows you to verify
that the download is successful before proceeding. Follow these guidelines to
establish an order in which to download the new software to GQAMs. The method
that you follow depends on the type of sessions that the modulator carries
(xOD/VOD sessions or broadcast sessions).
that the download is successful before proceeding. Follow these guidelines to
establish an order in which to download the new software to GQAMs. The method
that you follow depends on the type of sessions that the modulator carries
(xOD/VOD sessions or broadcast sessions).
CAUTION:
If you are downloading new software to more than one GQAM modulator
group, download the software to one modulator group (for example, all
modulators in a single rack or hub) and verify its functionality before
attempting to download software to another modulator group. Verifying the
functionality of one modulator group at a time enables you to better isolate
any failures that may occur.

upgrade all modulators in one hub and verify the functionality of those modulators
before upgrading modulators in another hub.

within a hub:
1 If any GQAMs act as spares, download the software on these modulators first.
2 If your system does not have a spare GQAM, download the software on the

1 If any GQAMs act as spares, download the software on these modulators first.
2 If your system does not have a spare GQAM, download the software on the
modulator carrying the fewest number of sessions.
3 Continue downloading the software to modulators by working your way up to
the modulator carrying the most sessions.
