CAUTION:

To ensure adequate power and to avoid raising a power alarm, we recommend that you maintain n +1 power supplies in your router at all times. Replace failed power supplies immediately to prevent unexpected failures.

If a new line card is installed in an operational router, power management does not power on the line card if the increased power demand exceeds the total available power, including redundant power. If redundant power is used to power on the line card, a minor alarm is raised, which becomes a major alarm in five minutes if the condition is not corrected.

You can view the total power provided to the chassis, the power required to operate the chassis and the components installed in it, and the balance power available in the chassis by using the show chassis power detail command.

JNP10K-PWR-AC2 Power Specifications

The JNP10K-PWR-AC2 power supply supports AC, HVAC, and HVDC. You can run the JNP10K-PWR-AC2 power supply in either JNP10008-SF or in JNP10008-SF3 fabric systems. However, if you are upgrading a JNP10008-SF system to use JNP10K-PWR-AC2 power supplies, also upgrade your fans and fan tray controllers to ensure the proper airflow. JNP10K-PWR-AC2 power supplies require JNP10008-FAN2 and JNP10008-FTC2 cooling systems.

Table 2 lists the power specifications for the AC power supply (JNP10K-PWR-AC2) used in a PTX10008 chassis.

JNP10K-PWR-AC2 Power Cable Specifications

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 router. An AC power cord connects each power supply to the power distribution panel.

Note:

In North America, AC power cords must not exceed 15 feet (approximately 4.5 meters) 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 shipped with the router to North America and Canada are in compliance.

PTX10008 AC, high-voltage alternating current (HVAC), and high-voltage direct current (HVDC) power supplies have specific cord requirements. Use the following sections to determine the cable requirements based on the model of your power supply and any mode settings:

JNP10K-PWR-AC2 Power Cable Specifications

When the JNP10K-PWR-AC2 power supply is operating in 20-A mode, it has an output of 2700-W with a single feed and 3000-W with dual feeds. Table 4 shows the cables appropriate for 20-A input. Table 5 shows the cable appropriate for HVAC input.

Warning:

Do not run JNP10K-PWR-AC2 power supplies using 16-A or 20-A cables if connected to 30-A input.

CAUTION:

You can prevent AC power cables from being exposed to hot air exhaust by always routing the power cables away from the fan trays and power supplies.

CAUTION:

It is important to connect both input feeds of the JNP10K-PWR-AC2 power supply to AC mains before loading the system with power.

Note:

The cables that we ship are 4.5 m long and come with AWG or mm² wire size depending on your country or region.

JNP10K-PWR-AC2 Power Cable Specifications for 30-A Input

The JNP10K-PWR-AC2 HVAC or HVDC power supply requires a high voltage cable assembly when set for 30-A input. One end of the cable has an Anderson APP-400 connector, while the other end of the cable is bare wire. See Figure 1 and Table 6. These cables are separately orderable and are not shipped automatically with JNP10K-PWR-AC2 orders. An example of the right-angle cable and connector is shown in Figure 3.

For connection to AC systems, Juniper provides a cable with either a NEMA 30-A connector (Figure 1) or an IEC 330P6W connector (Figure 2).
