4.2.1.2 Power Requirements
Make sure that the board is used in Centellis 2x00 AdvancedTCA shelf. If the module is
used in a Centellis 2x00 DC version shelf, make sure it is connected to -48VDC up to
-60VDC (rated voltage), according to Telecommunication Network Voltage (TNV-2).
A TNV-2 circuit is a circuit whose normal operating voltages exceed the limits for a safety-
extra-low-voltage (SELV) under normal operating conditions, and which is not subject to
over voltages from telecommunication networks.
On-board voltages are 5.0VDC, 3.3VDC and 1.0VDC:
5.0V voltage is generated from the -48V AdvancedTCA power by a DC/DC converter with
galvanic isolation suitable for TNV-2 circuits.
3.3V and 1.0V voltages are derived from the 5.0V power.
The board provides two independent power inputs according to the AdvancedTCA
specification. Each input has to be equipped with an additional fuse of max. 90A located
either in the shelf where the board is installed or the power entry module (PEM).
