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 overvoltages from
telecommunication networks.
Table 2-3 lists the power requirements for the ATCA-7350.
Free Fall 1,200 mm (Packaged) /all
edges and corners
1.0m (Packaged) per ETSI 300
019-2-2 (Blade level
packaging)
25 mm (unpackaged) per GR-
63-CORE
1. When operated in 55C ambient temperature and depending on the shelf's cooling capabilities the board is plugged
into, the SAS hard disk surface temperature exceeds the specified maximum limit of 60C.
2. The SAS drives can meet this max temperature range of non-operating.
3. The vibration tolerance can be further limited due to the hard disk you are installing on the blade. Please refer to the
respective datasheet for further information.
