The blade must be connected to a TNV-2 or a safety-extra-low-voltage (SELV) circuit. A TNV-2
circuit is a circuit whose normal operating voltages exceed the limits for a SELV circuit under
normal operating conditions, and which is not subject to over voltages from
telecommunication networks.
The following table provides information about the maximum power consumption of ATCA-
7480 all variants equipped with DIMIs, SSDs, and RTM-ATCA-748x-40G including 4x QSFP. The
table also contains power consumption details of blade without any RTM.
