One Forwarding Engine Board (FEB)
Eight Flexible PIC Concentrator (FPCs), as follows:
Six ACX-FPC-20Y
One ACX-FPC-16C
One ACX-FPC-4CD
Two JNP5700-FAN fan trays
Two JNP-3000W-AC-AFO or JNP-3000W-DC-AFO power supplies

|---|---|---|---|
ACX7509-RCB | RCB 0 | 60 W | 70 W |
ACX7509-FEB | FEB 0 | 356 W | 468 W |
ACX-FPC-20Y | FPC 0, 2, 3, 4, 6, and 7 | 70 W * 6 = 420 W | 74 W * 6 = 444 W |
ACX-FPC-16C | 1 | 122 W | 133 W |
ACX-FPC-4CD | 5 | 102 W | 114 W |
JNP5700-FAN | Fan Tray 0 and Fan Tray 1 | 80 W * 2 = 160 W | 336 W * 2 = 672 W |
PSM power loss with 92% efficiency | 160.16 W | 187.68 W | |
Total power requirement | 1380.16 W | 2088.68 W | |
Total power requirement (in Watts) with 92% efficiency | Power requirement in watts / power supply efficiency @92% = power consumption in watts: 1380.16 / 0.92 = 1500 | Power requirement in watts / power supply efficiency @92% = power consumption in watts: 2088.68 / 0.92 = 2270 |
Table 4 lists the power requirements for the fully configured ACX7509-BASE router with AC or DC PSMs.

System Thermal Output Calculation
After you have calculated the power consumption for your configuration, you can use that information to determine the system thermal output in Basic Transmission Units (BTUs) per hour. To do so, multiply the power consumption in watts by 3.41.
For example, in Power Requirement Calculation for an ACX7509-BASE Router, we calculated the power consumption for a fully configured ACX7509-BASE chassis running at high activity, with SFP28, QSFP28, QSFP56-DD optics, and AC PSMs, to be 1500 W. Using that information we can calculate the system thermal output for the configuration as follows:
Power consumption in watts * 3.41 = system thermal output in BTU/hr 1500 W * 3.41 = 5115 BTU/hr
