The following sample configuration shows an SRX5400 Services Gateway chassis with
various power supplies and:
One SRX5K-SPC-4-15-320 Services Processing Card (SPC) (slots 1 and 2)
One SRX5K-MPC with two MICs installed in it (slot 1/0)
One SRX5K-SCB switch control board (SCBs with one SRX5K-RE-13-20 Routing Engine
installed in it (SCB slot 0)
Calculate the power requirements (usage) as shown in

Evaluate the power budget. In the case of a DC-powered chassis, evaluate the budget

for each zone. In this step, we check the required power against the maximum output
power of available power supply options.
NOTE: The power for the cooling system comes from a different tap on
the power supply, reserved for the cooling system only. The cooling system
power requirement does not need to be deducted from the output power
budget of the power supply.
Table 24 on page 191 lists the power supplies, their maximum output power, and
unused power (or a power deficit) for an AC-powered services gateway.
Table 25 on page 191 lists the power supplies, their maximum output power, and unused
power (or a power deficit) for an AC-powered services gateway.
