PTX10000 Power System

 

You can install up to six power supplies in a PTX10008 router in the slots labeled PEM 0 through PEM 5 (top to bottom) located in the rear of the chassis. In the PTX10016, 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.

JNP10K-PWR-AC Power Supply

The JNP10K-PWR-AC power supplies are 2700-W and support 200–240 VAC. The output is 12 VDC; 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.

All base configuration PTX10008 routers are shipped with three power supplies; base configuration PTX10016 routers are shipped with five power supplies. Cover are installed over the remaining power supply slots. You can add additional power supplies to base configuration routers as necessary. For details about different router configurations, see PTX10008 Components and Configurations and PTX10016 Components and Configurations.

Each JNP10K-PWR-AC power supply weighs 6.8 lb (3.08 kg) and has 2 independent 16 A rated AC inlets on the faceplate. Although 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.

PTX10000 routers employ automatic transfer switch (ATS) technology. The system provides 2n source redundancy and n+1 power supply redundancy, allowing you to use fewer power supplies than you would require in a 2n configuration. Should one power source fail, ATS routers the power supply to the alternate source.

Note

For redundancy, always plug the two power cords from each power supply:

  • INP1 into a UPS

  • INP2 into the public electricity supply

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. See Figure 1.

Figure 1: JNP10K-PWR-AC Power Supply
JNP10K-PWR-AC Power
Supply

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 for installing the power cord retainers, see Connecting AC Power to a PTX10000.

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.

Retainer for an JNP10K-PWR-AC Power Supply

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, high-line model that is designed to support either AC or DC systems in either a low power or high power mode. The power supply takes AC input and provides DC output of 12.3 VDC, 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 provides high or low output power is configured using a set of dip switches on the faceplate of the power supply. If any power supply in the chassis is set to low power, all power supplies are also set to low power, regardless of their dip switch settings. This design is to prevent overloading of the power supply that is set to low power. See Table 1.

The JNP10K-PWR-AC2 fits into the standard power supply bay but when compared to most other models, the JNP10K-PWR-AC2 is longer and protrudes from the bay when fully inserted into the chassis. See Figure 3 for the settings for the dip switches.

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 of 158°F (70°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.

The JNP10K-PWR-AC2 requires the enhanced power bus to operate at full power. You can use the standard bus, but available power is 3000 W for power budget from the power management software. To determine whether your system has the standard power bus or the enhanced power bus, see PTX10000 Status Panel LEDs.

JNP10K-PWR-DC Power Supply

The PTX10000 supports three types of DC power supply modules:

  • JNP10K-PWR-DC—A 2500-W, 12-VDC dual power supply.

  • JNP10K-PWR-DC2—A 5500-W, 12-VDC quad input power supply. For details on this power supply, see JNP10K-PWR-DC2 Power Supply.

  • JNP10K-PWR-AC2—An AC, high-voltage alternating current (HVAC,) or high-voltage direct current (HVDC) power supply. In high power mode, this power supply provides 12.3 V, 5000 W with a single feed and 5500 W with dual feeds. For details on this power supply, see JNP10K-PWR-AC2 Power Supply.

All three power supplies fit into a power slot bay, but the JNP10K-PWR-AC2 and JNP10K-PWR-DC2 are longer and protrude from the bay when fully inserted into the chassis. See Figure 4.

and JNP10K-PWR-DC2 Power Supplies
Caution

Do not mix power supply models in the same chassis in a running environment. DC and HVDC can coexist in the same chassis during the hot swap of DC for HVDC.

The DC power supply, JNP10K-PWR-DC, is a 2500-W, 12-VDC, dual input power supply. The output of each DC power supply is 12-VDC. 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 PTX10000 routers. For details about different chassis configurations, see PTX10008 Components and Configurations and PTX10016 Components and Configurations.

Each JNP10K-PWR-DC power supply weighs approximately 6 lb (2.7 kg) and 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 to a dedicated DC power feed to provide redundancy. Only one power feed is operational at a time.

DC power models employ electronic A-B input selection. It provides 2n source redundancy and n+1 power supply redundancy using fewer power supplies than you would require in a 2n configuration. Should one power source fail, electronic A-B input selection routes the power supply to the alternate source.

Each JNP10K-PWR-DC 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. See Figure 5.

Figure 5: JNP10K-PWR-DC Power Supply
JNP10K-PWR-DC Power
Supply
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 PTX10008 router or 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.

You can only use JNP10K-PWR-DC power supplies in the standard chassis, which uses the standard power bus.

A JNP10K-PWR-DC power supply can operate with only one input DC feed connected. The Routing Control Board only enables the components for which sufficient power is available.

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. PS_0 and PS_1 each have redundant input feeds: A0 and/or B0 for PS_0 and A1 and/or B1 for PS_1. The input is configured using a set of dip switches on the power supply faceplate. The output is dependant on the settings of these dip switches. See Table 2. This power supply requires the enhanced power bus. See Figure 6.
