Miscellaneous rear panel connectors
GPIO/TC - General Purpose / Time Code connector
This connector is reserved for future use.
Console A & B connectors
These connectors are for factory use.
Control Connector
This connector is reserved for future use.
Power Supply Notes
Power supply specifications are shown on page 79.
Ventilation is critical for Trinix power supplies, which should not be run
with the fan not working. (If the supply begins to overheat it will shut
itself off automatically to prevent damage.) The use of redundant
power supplies is highly recommended.
DV-33128 and DV-33256 Chassis Installations
AC Applications
Power supplies are factory-installed and designed to be hot-swappable.
Note Fuses must be selected and installed as appropriate for mains voltage.
For systems with only one power supply, SR/NR-33000 sync card(s)
jumper JN2 must be set to “DC,” otherwise the red “PALARM” LED on
the front edge of the SR/NR(s) will remain on. If a redundant power
supply is installed at a later time, JN2 must be moved to “AC.” See
page 120.
DC Applications
Connect the DC Input connector to a DC source.
Note For DC applications fusing must be provided externally, in accordance
with local electrical regulations. DC input specifications and character-
istics for the Trinix are shown on page 80.
Check to see that the SR/NR-33000 sync card(s) have jumper JN2 set to
“DC.” See page 120.
Simultaneous AC and DC Applications
It is possible to connect both AC and DC power sources as part of a
system redundancy scheme. In this case, refer to the AC and DC notes
above. SR/NR-33000 jumper JN2 should be set to “AC.”
