Configuring GQAMs as BFS QAMs
for Separable Security Host Set-Tops
Background
Some customers are now choosing to configure GQAMs as BFS QAMs in their
networks. In this configuration, if you are doing a software upgrade of your
Separable Security (SSC) host set-tops with PowerKEY® Multi-Stream
CableCARD™ Modules, (M-Card™ modules), the software may not successfully
download from the BFS GQAM to the SSC host set-tops. To ensure the BFS
GQAM successfully downloads software to the host set-tops, it is recommended
that your GQAMs operate at software version 4.0.15 (or later) and you change the
bootloader carousel program number to 260. A software change in GQAM 4.0.15
generates the correct packet length for the program number 260 and allows the
upgrade to successfully complete.

Recommendation
This recommendation requires all three steps be followed for the BFS GQAMs to
operate correctly:
Running GQAM software version 4.0.15 or later
Changing the program number
Tearing down and restarting the 199 session
Important: Since the operator is tearing down and restarting the 199 session, it is
recommended that this procedure be completed during a maintenance window.
