The order in which you download new software onto Netcrypt Bulk Encryptors
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 Netcrypt

the Netcrypt Bulk Encryptor encrypts (xOD/VOD sessions or broadcast sessions).
CAUTION:
If you are upgrading more than one Netcrypt Bulk Encryptor, download the
new software to one bulk encryptor group (for example, all bulk encryptors in
a single rack or hub) and verify its functionality before attempting to
download the software to another bulk encryptor group. Verifying the
functionality of one bulk encryptor group at a time enables you to better
isolate any failures that may occur and enables you to minimize service
interruptions.

software on the unit carrying the fewest number of sessions.
3 Continue downloading the software to Netcrypt Bulk Encryptors by working
your way up to the unit carrying the most sessions.
