Juniper SRX5400 - Page 154

The following sample configuration shows an SRX5400 Services Gateway chassis with various power
supplies and:
•
Two SRX5K-SPC-4-15-320 (SPC2) Services Processing Card (SPC) (slots 1 and 2)
•
One SRX5K-MPC (IOC2) with two MICs installed in it (slot 1/0)
•
One switch control board SRX5K-SCB (SCB1) or SRX5K-SCBE (SCB2) and one Routing Engine
SRX5K-RE-13-20 (RE1) or SRX5KRE-1800X4 (RE2) installed in it (SCB slot 0)
1. Calculate the power requirements (usage) as shown in Table 33 on page 155.

2. Evaluate the power budget. In this step, we check the required power against the maximum output
power of available power supply options.
