CHAPTER 3 INSTALL BLADES

Plan Distribution of Blades

Plan the distribution of the blades for the
across the slots. Blank filler plates are needed for unused slots. This ensures proper airflow through the chassis,
which prevents overheating.
Arrange the blades as follows (See Figure 2.):
• Slots 1-12 are designed for Low Bandwidth blades and provide a connection to the RF backplane and digital
backplane. (Low bandwidth = 2 Gigabit connection)
– The Satellite Receiver Blade(s) must be placed in slots 1-12 to have the required connection to the
RF backplane.
– QAM 16 blades, NTSC blades and ATSC blades are Low Bandwidth blades and can be placed
into any slot.
• Slots 13-16 are designed for High Bandwidth blades and provide a higher bit rate connection to the digital
backplane. (High Bandwidth = 5 Gigabit connection)
– QAM 48 blades and QAM 96 blades are High Bandwidth blades and must be placed in these slots to
perform correctly.
NOTES:
• Every SMARTBOX must have at least one satellite receiver blade to operate.
• Installations requiring transcoding must have only satellite receiver blades with transcoder modules,
otherwise
the system will perform intermittently.
• A scrolling Program Guide is always an available service in Native (MPEG-4) format digitally and via NTSC
output in Bulk Distribution environments; it requires two satellite receiver blades, proper output blades, and
output authorizations to operate.
• Blades and power supplies are hot-swappable. To swap a power supply, first you must remove the power
cord. After swapping a satellite receiver blade, a software update, .csv download/upload to Salesforce.com,
and an authorization hit may be needed.
• If a part is missing, contact DISH or your distributor for replacement.
