AC Power Circuit Breaker Specifications

Each AC power supply has a single AC appliance inlet located on the power supply that requires a dedicated AC power feed. We recommend that you use a customer site circuit breaker rated for 15 A (250 VAC) minimum for each AC power supply, or as permitted by local code. Doing so enables you to operate the services gateway in any configuration without upgrading the power infrastructure.

Power Requirements for AC-Powered Services Gateways

Note: If you plan to operate a maximally configured AC-powered services gateway, we recommend that you provision 33 A @ 100 VAC or 14 A @ 240 VAC for the system, or 11.0 A @ 200 VAC or 14.5 A @ 110 VAC for each power supply.

If you do not plan to provision 33 A @ 100 VAC or 14 A @ 240 VAC for the system, or 11.0 A @ 200 VAC or 14.5 A @ 110 VAC for each power supply, you can use the information in Table 37 and Table 38 to calculate power consumption for various hardware configurations, and thermal output.

Table 37 lists the power requirements for base AC-powered devices operating under typical voltage conditions. It includes the efficiency for the AC power supplies.

Table 37: Base System AC Power Requirements

Component

Power Requirement (Watts)

Low-line nonredundant configuration @ 110 V includes three AC power supplies, midplane, craft interface, and the fan tray (running at normal speed)

455 W (approximate)

Low-line redundant configuration @ 110 V includes four AC power supplies, midplane, craft interface, and the fan tray (running at normal speed)

585 W (approximate)

High-line nonredundant configuration @ 220 V includes two AC power supplies, one Routing Engine, one SCB, midplane, craft interface, and the fan tray (running at normal speed)

410 W (approximate)

High-line redundant configuration @ 220 V includes four AC power supplies, midplane, craft interface, and the fan tray (running at normal speed)

745 W (approximate)

Table 38 lists the power requirements for various hardware components when the services gateway is operating under typical voltage conditions.

Table 38: Component Power Requirements

AC Power Cord Specifications

Each AC power supply has a single AC appliance inlet located on the power supply that requires a dedicated AC power feed. Most sites distribute power through a main conduit that leads to frame-mounted power distribution panels, one of which can be located at the top of the rack that houses the device. An AC power cord connects each power supply to the power distribution panel.

Detachable AC power cords, each 2.5 m (approximately 8 ft) long, are supplied with the services gateway. The C19 appliance coupler at the female end of the cord inserts into the AC appliance inlet coupler, type C20 (right angle) 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 39 provides specifications and Figure 76 depicts the plug on the AC power cord provided for each country or region.

Warning: The AC power cord for the services gateway is intended for use with the services gateway only and not for any other use.

Note: 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 services gateway are in compliance.

For information about the AC power supply, including a description of components, see AC Power Supply. For instructions on connecting the power cord during initial installation, see Connecting Power to an AC-Powered Services Gateway. For instructions on replacing the AC power cord, see Replacing an AC Power Cord.
