AC Power Specifications and Guidelines

Item	Specification
AC input voltage	Operating range: 100 - 240 VAC
AC input line frequency	50 to 60 Hz (nominal)
AC system current rating	33 A @ 100 VAC or 14 A @ 240 VAC maximum (11 A per inlet)

Table 36 lists the AC power supply electrical specifications. For AC power system electrical specifications, see Table 35.

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

Item	Specification
Maximum output power	1200 W (low line)/ 1700 W (high line)
AC input voltage	Operating range: 100 - 240 VAC (nominal)
AC input line frequency	50 to 60 Hz (nominal)
AC input current rating	11.0 A @ 200 VAC or 14.5 A @ 110 VAC maximum

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.

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.

Component	Power Requirement (Watts)
Fan tray (full speed) – Fan tray (normal speed)	110 W – 80 W = 30 W
SCB	150 W
Routing Engine	90 W
IOC—Generalized typical value	312 W
IOC—Generalized maximum value	365 W
SPC—Generalized typical value	213 W
SPC—Generalized maximum value	351 W

Minimum AC-powered low-line configuration @ 110 V:


                  
                     Base device (low-line nonredundant) + 1 SCB

                        = 1220 W

Maximum AC-powered low-line configuration @ 110 V:


                  
                     Base device (low-line redundant) + fan tray

                        maximum value=
                     
                     585 W + 30 W + 2(150) W + 90 W + (5)365 W
                        + 351 W= 
                     
                     585 W + 30 W + 300 W + 90 W + 1825 W
                        + 351 W = 3181 W

Typical system thermal output (based on maximally configured AC-powered services gateway @ 110 V input):


                  
                     Watts  * 3.41 = BTU/hr
                      3181 W * 3.41 = 10,847 BTU/hr

                     745 W + 30 W + 2(150) W + 90 W + (5)365 W
                        + 351 W = 
                     
                     745 W + 30 W + 300 W + 90 W + 1825 W
                         + 351 W = 3341 W

Typical system thermal output (based on maximally configured AC-powered services gateway @ 220 V input):


                  
                     Watts  * 3.41 = BTU/hr
                      3341 W * 3.41 = 11,393 BTU/hr

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.
