Centellis 2x00 User Card-10GE Installation and Use (6806800H33E) 31
2.4 Power Supply
The Centellis 2x00 User Card-10GE is powered by dual redundant -48VDC to -60VDC
(rated voltage) from the backplane connector. The IPMC is powered by 3.4V from the shelf
manager part of the board via the backplane.
The power supply of the shelf manager is compliant with the requirements of the PICMG
3.0 R3.0 (AdvancedTCA) specification. Each of the four power connections is separately
fused. Fuse rating is 1A.
An EMI filter at the power input ensures conducted emission levels below EN 55022 class
B.
2.4.1 On-board and External Supply
The Centellis 2x00 User Card-10GE has no provisions to switch off the power input. The
board is powered whenever the power is attached to the Centellis 2x00 system (-40VDC to
-72VDC).
The board satisfies the standby power limit of 10W for AdvancedTCA FRUs. Typical power
consumption of the Centellis 2x00 User Card-10GE board is 2.8W.
2.4.2 Power Supply Holdup
The Centellis 2x00 User Card-10GE complies with the requirements for board level voltage
transients as described in chapter 4.1.4.3. of PICMG 3.0 (AdvancedTCA) specification .
It satisfies the requirement of uninterrupted operation during a power failure of 5ms.
