Installing CAP Ms
Determine the Power Consumption of the CAP M
Use the power consumption matrix in Table 5 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 5 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.
Determine the Mounting Site
When deciding on a suitable mounting site, observe the following rules; refer also to "Mounting Orientation”
on page 24 .
•
The CAP M is suitable for installation indoors or outdoors.
•
Use the weights listed in Table 6 to determine a site that can bear the weight of the CAP M that is being
installed, where:
–
The “Maximum Lift Weight” is the highest weight that must be lifted during installation. (An installer
should lift the CAP M components one at a time, not a wholly configured CAP M.)
–
The “Total Hanging Weight” is the weight of the CAP M, including the weight of the Mounting Bracket,
minus the weight of the external cables and connectors, that the mounting site must be able to
support.
•
Use the dimensions shown in Figure 4 on page 17 for Single Mount and Figure 5 on page 18 for Dual
Mount.

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.
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 max. or 240 Volt / 16 Amp, single-phase, 50 / 60 Hz AC
service is needed, i.e. the external AC breaker should be 20 Amps max. 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.
