PTX10016 Power System
PTX10016 routers support AC, DC, high-voltage alternating current (HVAC), and high-voltage direct current (HVDC) by offering the following power supplies:
-
JNP10K-PWR-AC
-
JNP10K-PWR-AC2
-
JNP10K–PWR-DC
-
JNP10K-PWR-DC2
You can install up to 10 power supplies in the slots labeled PEM 0 through PEM 9 (top to bottom) located in the rear of the chassis. All models of the power supply operate in JNP10016-SF fabric systems. The JNP10016-SF3 switch fabric requires the JNP10K-PWR-AC2 or the JNP10K-PWR-DC2 power supply.
The JNP10K-PWR-AC2 and JNP10K-PWR-DC2 power supplies share power. The JNP10K-PWR-AC and JNP10K-PWR-DC power supplies do not share power.
JNP10K-PWR-AC Power Supply
The JNP10K-PWR-AC power supplies are 2700-W and support 200–240 VAC. The output power is 2700 W.
Do not mix AC and DC power supplies in the same chassis. AC and HVAC can coexist in the same chassis during the hot swap of AC for HVAC. Do not mix AC and HVAC power supplies in a running environment.
The router is pluggable type A equipment installed in a restricted-access location. It has a separate protective earthing terminal on the chassis that must be connected to earth ground permanently to ground the chassis adequately and protect the operator from electrical hazards.
Before you begin installing the router, ensure that a licensed electrician has attached an appropriate grounding lug to the grounding cable that you supply. Using a grounding cable with an incorrectly attached lug can damage the router.
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.
Each JNP10K-PWR-AC power supply has two independent 16-A rated AC inlets on the faceplate. Though each inlet provides sufficient input power to provide full output, always connect to a dedicated AC power feed to provide redundancy. Only one power feed is operational at a time.
For redundancy, always plug the two power cords from each power supply:
-
INP1 into the public electricity supply
-
INP2 into an alternative or independent power source
Each JNP10K-PWR-AC power supply has a power switch with international markings for on (|) and off (O), a fan, and four LEDs on the faceplate that indicate the status of the power supply. It also has a set of dual inline package (DIP) switches that enable the source feeds, INP1 and INP2. See Figure 1.
Use a 2-pole circuit breaker rated at 25 A in the building installation and the system, or as per local electrical code.
Each JNP10K-PWR-AC power supply comes with two power cord retainers that hold the power cords in place. See Figure 2. Each power cord retainer has a clip and an adjustment nut. The ends of the clip hook into the bracket holes on each side of the AC appliance inlet on the faceplate. The adjustment nut holds the power cord in the correct position.
Route all the AC power supply cords away from the fan trays and power supply vents. Make sure that the power cords do not obstruct the fan trays or power supply vents.
Each power supply connects to the power rail in the router. The power rail distributes the output power produced by the power supplies to different router components. Each power supply provides power to all the components in the router.
Each power supply has its own fan and is cooled by its own internal cooling system. Hot air exhausts from the rear of the chassis.

JNP10K-PWR-AC2 Power Supply
The JNP10K-PWR-AC2 power supply is a high-capacity model that is designed to support AC, high-voltage AC (HVAC), or high-voltage DC (HVDC) systems in either a 20-A or a 30-A mode; see Figure 3. The power supply feeds AC input and provides DC output of 5000 W with a single feed and 5500 W with a dual feed. The operating input voltage range is 180 to 305 VAC for AC systems and 190 to 410 VDC for DC systems.
The number of power feeds and whether the power supplies provide high-output (30-A) or low-output (20-A) power are configured using a set of dual inline package (DIP) switches on the faceplate of the power supply. If one power supply in the chassis is set to low power, the power budget for the chassis is reduced to low power, regardless of their DIP switch settings or the output results in the CLI. This design safeguards against accidentally setting the power supply to 30 A in a facility that can provide only 20 A and tripping the facility circuit breaker. We recommend that you don’t mix DIP switch settings in your system. See Table 1 for information about the input and output voltages when you use the DIP switches.
Extreme burn danger—Do not handle an HVAC or HVDC power supply running in the chassis without heat protective gloves. The JNP10K-PWR-AC2 can reach temperatures in the range of 158°F to 176°F (70°C to 80°C) under running conditions.
The router is pluggable type A equipment installed in a restricted-access location. It has a separate protective earthing terminal on the chassis that must be connected to earth ground permanently to ground the chassis adequately and protect the operator from electrical hazards.
Before you begin installing the router, ensure that a licensed electrician has attached an appropriate grounding lug to the grounding cable that you supply. Using a grounding cable with an incorrectly attached lug can damage the router.
Use a 2-pole circuit breaker rated at 25 A in the building installation and the system, or as per local electrical code.

It is important to connect both input feeds of the JNP10K-PWR-AC2 power supply to AC mains before loading the system with power.
The power supplies have internal fans that contribute to chassis cooling. Therefore, all the power supplies must be present in a running chassis to have the adequate airflow. While all power supplies are required to be present in the chassis, they do not necessarily be connected to power. If a power supply is installed in a slot but is not connected to a power source, it draws power from the chassis to power the internal fans in the power supplies.
JNP10K-PWR-DC Power Supply
The DC power supply, JNP10K-PWR-DC, is a 2500-W, dual input power supply. The output power is 2500 W.
The router is pluggable type A equipment installed in a restricted-access location. It has a separate protective earthing terminal on the chassis that must be connected to earth ground permanently to ground the chassis adequately and protect the operator from electrical hazards.
Before you begin installing the router, ensure that a licensed electrician has attached an appropriate grounding lug to the grounding cable that you supply. Using a grounding cable with an incorrectly attached lug can damage the router.
Each JNP10K-PWR-DC power supply has two independent pairs of DC input lugs (Input 1, RTN, –48V/–60V and Input 2, RTN, –48V/–60V) on the faceplate of the power supply. Each inlet requires a dedicated DC power feed. Although each inlet provides sufficient input power to provide full output, always connect the power supply to a dedicated DC power feed to provide redundancy. Only one power feed is operational at a time.
DC power supply models employ electronic A-B input selection. If one power source fails, the electronic A-B input selection routes the power supply to the alternate source. The power supply internally balances power between source input A and source input B. The default is to balance 50% to each input.
Each JNP10K-PWR-DC power supply has a power switch with international markings for on (|) and off (O), a built-in fan, and four LEDs on the faceplate that indicate the status of the power supply. See Figure 4.
The JNP10K-PWR-DC power supply requires a dedicated circuit breaker for each input DC feed. The chosen breaker should be sized to deliver 60 A of input current.
Each power supply connects to the combined power rail in a PTX10016 router. The power rail distributes the output power produced by the power supplies to different router components. Each DC power supply provides power to all the components in the router.
Route all the DC power supply cords away from the fan trays. Make sure that the power cords do not obstruct the fan trays.
A JNP10K-PWR-DC power supply can operate with only one input DC feed connected.
Each JNP10K-PWR-DC power supply has its own fan and is cooled by its own internal cooling system. The airflow is from the front of the power supply to the back. Hot air exhausts from the rear of the chassis.

JNP10K-PWR-DC2 Power Supply
The JNP10K-PWR-DC2 power supply provides two power supplies in a single housing that accepts either 60 A or 80 A using four redundant input power feeds. See Figure 5.
The two internal power supplies (PS 0 and PS 1) each have redundant input feeds: A0 and/or B0 provide power to PS 0 and A1 and/or B1 provide power to PS 1.The input feed A0 or B0 with the highest input voltage provides power to PS 0. Similarly, the input feed A1 or B1 with the highest input voltage provides power to PS 1. A0, B0, A1, and B1 share the power if the input voltage is the same. You configure the input using a set of three DIP switches on the power supply faceplate that sets the combined output power for both internal power supplies. The output depends on the settings of these DIP switches. See Table 2. The output of the PS 0 and PS 1 shares the output power.

A combined output of 5500 W with PS 0 and PS 1 active is available at 56 VDC or greater. If the input voltage is less than 56 VDC, the output power decreases linearly, keeping the input current a little below the default 60 A. However, the power supply supports 5500 W at lower input voltage if you provide 80 A and sets the power supply switch to 80 A setting.
A combined output of 2750 W with only PS 0 or PS 1 active is available at 56 VDC or greater. If the input voltage is less than 56 VDC, the output power decreases linearly, keeping the input current a little below the default 60 A. However, the power supply supports 2750 W at lower input voltage if you provide 80 A and sets the power supply switch to 80 A setting.
The JNP10K-PWR-DC2 power supply requires a dedicated circuit breaker for each input DC feed. You must use a circuit breaker that is rated for 80 A DC with medium delay.
The power supplies have internal fans that contribute to chassis cooling. Therefore, all the power supplies must be present in a running chassis to have the adequate airflow. While all power supplies are required to be present in the chassis, they do not necessarily be connected to power. If a power supply is installed in a slot but is not connected to a power source, it draws power from the chassis to power the internal fans in the power supplies.
