PTX10016 Power System

The JNP10K-PWR-AC power supplies are 2700-W and support 200–240 VAC. The output power is 2700 W.

CAUTION:

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.

Warning:

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.

CAUTION:

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.

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.

The number of power supplies furnished as standard varies by configuration model. For details about different router configurations, see PTX10016 Components and Configurations.

Each JNP10K-PWR-AC power supply has two independent 16-A rated AC inlets on the faceplate. Although each inlet provides sufficient input power to provide full output, always connect the inlets to a dedicated AC power feed to provide redundancy. Only one power feed is operational at a time. The JNP10K-PWR-AC does not share power; all power comes into INP1 (lower receptacle), and the power supply uses INP2 (top receptacle) only at failover.

Note:

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.

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. For instructions on installing the power cord retainers, see Connect AC Power to the PTX10016 Router.

Note:

Route all the AC power supply cords away from the fan trays. Make sure that the power cords do not obstruct the fan trays.

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.

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. The power supply feeds AC input and provides DC output of 5000 W with a single feed and 5500 W with a dual feed. For AC systems, the operating input voltage is 180 to 305 VAC and for DC systems, the operating input voltage is 190 to 410 VDC.

The number of power feeds and whether the power supplies provide high output (30-A) or low output (20-A) power is 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 CLI. This design safeguards against accidentally setting the power supply to 30 A in a facility that can only provide 20 A and tripping the facility circuit breaker. We recommend that you do not mix DIP switch settings in your system. See Table 1 for information about the input and output voltages when you use the DIP switches.

The JNP10K-PWR-AC2 fits into the standard power supply bay but when compared to the JNP10K-PWR-AC, the JNP10K-PWR-AC2 is longer and protrudes from the bay when fully inserted into the chassis. See Figure 3 for differences in power supply length.

All models of power supplies running in PTX10016 routers have internal fans that contribute to chassis cooling. However, the JNP10K-PWR-AC2 and JNP10K-PWR-DC2 power supplies play a more substantial role in cooling the chassis than the JNP10K-PWR-AC and JNP10K-PWR-DC models. Consequently, all six JNP10K-PWR-AC2 or JNP10K-PWR-DC2 power supplies must be present in a running chassis to have adequate airflow.

Warning:

Extreme burn danger—Do not handle an HVAC or HVDC power supply running in the chassis without heat protective gloves, such as welder’s gloves. The JNP10K-PWR-AC2 can reach temperatures between 158°F and 176°F (70°C to 80°C) under running conditions.

Warning:

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.

CAUTION:

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.

CAUTION:

Use a 2-pole circuit breaker rated at 25 A in the building installation and the system, or as per local electrical code.

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.

The DC power supply, JNP10K-PWR-DC, is a 2500-W, dual input power supply. The output power is 2500 W.

Warning:

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.

CAUTION:

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.

Note:

DC power supplies are shipped only in the redundant configuration of PTX10016 routers. For details about different chassis configurations, see PTX10016 Components and Configurations.

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.

Note:

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.

Note:

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.

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. The two internal power supplies (PS_0 and PS_1) each have redundant input feeds: A0 and/or B0 for PS0 and A1 and/or B1 for PS1. 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 and Figure 5.

Table 2: Power Input and Output Voltages for JNP10K-PWR-DC2 Power Supplies

PS0 (A0 or B0)	PS1 (A1 or B1)	H/L (High Input 80 A/Low Input 60 A)	Output Power
On	On	On (80 A)	5500 W
On	On	Off (60 A)	4400 W
On	Off	On (80 A)	2750 W
Off	On	On (80 A)	2750 W
On	Off	Off (60 A)	2200 W
Off	On	Off (60 A)	2200 W

The input capacitance value for the front-end EMI capacitor before the pre-charge circuit in the power supply is 12.2 uF. There is a 15,000 uF bulk capacitor after the pre-charge circuit.

The JNP10K-PWR-DC2 fits into the standard power supply bay but when compared to the JNP10K-PWR-DC, the JNP10K-PWR-DC2 is longer and protrudes from the bay when fully inserted into the chassis. See Figure 6 for differences in power supply length.

All models of power supplies running in PTX10016 routers have internal fans that contribute to chassis cooling. However, the JNP10K-PWR-AC2 and JNP10K-PWR-DC2 power supplies play a more substantial role in cooling the chassis than the JNP10K-PWR-AC and JNP10K-PWR-DC models. Consequently, all six JNP10K-PWR-AC2 or JNP10K-PWR-DC2 power supplies must be present in a running chassis to have the adequate airflow.

Note:

The JNP10K-PWR-DC2 power supply does not support 5500 W power if the inlet temperature to the power supply is 60° C or more. If your chassis is fully loaded and is running on JNP10K-PWR-DC2 power supplies, you might not have sufficient power to power all the components in the chassis if one of the power supplies is not operational.

CAUTION:

Do not mix power supply models in the same chassis in a running environment. JNP10K-PWR-DC and JNP10K-PWR-DC2 can coexist in the same chassis during power supply upgrades. Do not mix DC and HVDC power supplies in a running environment.

Warning:

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.

CAUTION:

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.
