Passive sub-rack (TPRN04)
• TPRN04 is a passive sub-rack. It cannot supply power to any inserted module, and
therefore is designed to host passive modules only. It can be useful in a multi-sub-rack
system, in case the customer decides to put all the active modules in an active sub-rack,
to be chosen among the following:
220 Vac powered sub-racks (TPRN14 / TPRN24)
• TPRN14 is an active sub-rack designed to be fed through 220 Vac universal mains. Both
the connector for the 220 Vac power supply and the communication ports are placed on
the rear of sub-rack. The 220 Vac power supply is not redundant (ie, no spare adapter is
provided).
• TPRN24 is an active sub-rack designed to be fed through 220 Vac universal mains. Both
the connector for the 220 Vac power supply and the communication ports are placed
on the rear of sub-rack, and the 220 Vac power supply is redundant: i.e., a spare adapter
guarantees the correct system operations even if the main 220Vac adapter has a
breakdown.
-48Vdc powered sub-rack (TPRN34)
• TPRN34 is an active sub-rack designed to be fed through a –48 Vdc negative supply. Both
the connector for the -48Vdc power supply and the communication ports are placed on
the rear of the sub-rack.
