Installing CAP Ms
Determine the Power Consumption of the CAP M
Use the power consumption matrix in Table 6 to calculate power consumption for a CAP M, where
• the consumption
numbers are at the CAP M power inputs and do not account for feed losses
• the
maximum consumption numbers in Table 6 do not include the power consumed by any attached
auxiliary devices. Both CAP M power consumption and auxiliary device
power must be included when
calculating feed losses.

1 Does not include SFP+ Module consumption. Can support up t
o 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 M 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.
• For the AC power supply, 120 Volt / 20 Amp maximum or 240 Volt
/ 16 Amp, single-phase, 50 / 60 Hz
AC service is needed. That is, the external AC breaker should be 20 Amps maximum for 120-Volt
service, or 13 to 16 Amps for 240-Volt service.
• For the DC power supply, observe the local
regulations of the DC service provider.
