Installing CAP MXs
Determine the Power Consumption of the CAP MX
Use the power consumption matrix in Table 7 to calculate power consumption for a CAP MX, where
• the consumption numbers are at the CAP MX power inputs and do not account for feed losses
• the maximum consumption numbers in Table 7 do not include the power consumed by any attached
auxiliary devices. Both CAP MX power consumption and auxiliary device power must be included when
calculating feed losses.

1 Does not include SFP+ Module consumption. Can support up to 3W (more with engineering consultation) maximum
total SFP+ Module consumption. Typical installation (sufficient for SM up to 10km or MM) would be 0.8W typical, 1.0W
max for each SFP+ Module.
2 Does not include power drawn by an external PoE device connected to the RJ45 Auxiliary port (Port A); in this
configuration, the CAP MX will draw an additional 20W.
Mains power must be interruptible with an external delay-actions mains breaker. For the Mains breaker,
observe the following recommendations.
• CAP MX APs require a minimum 120 Volt / 15 Amp or 240 Volt / 13 Amp, single-phase, 50 / 60 Hz AC
service. MAINS power must be interruptible with an external delay-actions mains breaker.
CommScope recommends external AC breakers capable of at least 15 Amps maximum for 120-Volt
service or at least 13 Amps for 240-Volt service. One type B breaker can support up to two CAP MX
units, and a type C breaker can support up to four CAP MX units.
• For the DC power supply, observe the local regulations of the DC service provider.
