2.3.2 Power Requirements
Make sure that the blade is used in an AdvancedTCA shelf connected to -48VDC up to -60VDC,
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.
