AC Grounding and Power Cord Specifications

To ground an AC-powered router, plug each power supply into a grounded AC power
receptacle. The receptacle provides the grounding for the router, so no additional grounding
is necessary. The receptacle must be within about 8 ft (2.5 m) of the router and must be
easily accessible.
Detachable AC power cords, each 2.5 m (approximately 8 ft) long, are supplied with the
router. The appliance coupler at the female end of the cord inserts into the appliance inlet on
the faceplate of the AC power supply. The coupler is type C13 as described by International
Electrotechnical Commission (IEC) standard 60320. The plug at the male end of the power
cord fits into the power source receptacle that is standard for your geographical location.
Table 10 provides specifications and Figure 18 depicts the plug on the AC power cord
provided for each country or region.

Table 10: AC Power Cord Specifications

If you plan to operate a maximally configured DC-powered router, we
recommend that you provision at least 13.5 A @ 48 VDC and use a facility
circuit breaker rated for 20 A minimum. Doing so enables you to operate
the router in any configuration without upgrading the power infrastructure,
and allows the router to function at full capacity using one power supply.
If you plan to operate a DC-powered router at less than the maximum
configuration and do not provision a 20 A circuit breaker, we recommend
that you provision a circuit breaker rated for at least 125% of the continuous
current that the system draws at 48 V.
In North America, AC power cords must not exceed 4.5 m (approximately
14.75 ft) in length, to comply with National Electrical Code (NEC) Sections
400-8 (NFPA 75, 5-2.2) and 210-52, and Canadian Electrical Code (CEC)
Section 4-010(3). The cords supplied with the router are in compliance.
