PTX10003 Power System

 

The PTX10003 is powered by 3000-W redundant AC/HDVC or DC power supplies that are pre-installed at the factory. The PTX10003-160C is powered by four power supplies for 2+2 redundancy. The PTX10003-80C is powered by two power supplies for 1 + 1 redundancy. The power supplies are hot-removable and hot-insertable. If one power supply fails, you can replace it without powering off or disrupting the routing function. The other power supply balances the electrical load without interruption. Each power supply has two outputs: 12 V and 12 V standby. Two counter-rotating fans in each power supply provide front to back cooling. The input voltages are as follows:

  • AC input voltage range: 200—277 V/50—60 Hz

  • DC input voltage range: —40 VDC Min, —72 VDC maximum

Caution

Do not mix AC/HVDC and DC power supplies in the same chassis.

PTX10003 AC/HVDC Power Supply Description

The input power to the AC/HVDC power supplies can be AC power or HVDC power. The power supplies automatically detect whether there is AC or HVDC input voltage and manage the power accordingly. AC power can be 180—305 VAC input voltage and HVDC power can be 190—400 VDC input voltage. Each 3000- W AC/HVDC power supply module has a single AC or HVDC input and provides 12 V power to the system.

Figure 1 shows the location of the AC/HVDC power supplies on the PTX10003-160C FRU panel, and Figure 2 shows the location of the AC/HVDC power supplies on the PTX10003-80C FRU panel.

PTX10003 DC Power Supply Description

The PTX10003 DC power supplies are hot-removable and hot-insertable FRUs. Each 3000 W power supply has a single DC input and provides 12 VDC output with a standby voltage of 12 VDC.

PTX10003 DC Input Current Selector (DIP Switch)

The PTX10003 DC power supply can operate with an input current of 80 A or 60 A. You select the input rating by moving the DC input current selector (DIP switch) to the desired setting. Refer to Figure 7 for the location of the DC input current selector (DIP switch). If you select 60 A, the power supply limits the output power so that the input current does not exceed 60 A under normal steady-state operation. If you select 80 A, the power supply limits the output power so that the input current does not exceed 80 A.

Caution

The PTX10003 DC power supply does not support a 60 A power source in Junos OS Evolved software release 19.1. When installing the PTX10003 DC power supply, be sure you set the DC input current selector (DIP switch) to 80 A.

For example:

If you select...

Then...

60 A

The power supply limits the output power to 2200 W at 40 V input and linearly increases the output power if the input voltage increases. The power supply provides 3000 W output power for input voltage greater than 55 V assuming 92% efficiency.

Caution: The PTX10003 DC power supply does not support a 60 A power source in Junos OS Evolved software release 19.1. When installing the PTX10003 DC power supply, be sure you set the DC input current selector (DIP switch) to 80 A.

80 A

The power supply provides 3000 W output power throughout the input voltage range from 40 VDC to 72 VDC.

PTX10003 DC Power Redundancy

To provide power redundancy for the PTX10003, the power supply modules must be connected to an 80 A power source and the input current selector (DIP switch) on the power supply must be set to 80 A. For the PTX10003-80C, the maximum power budget is 3000 W. For the PTX10003-160C, the maximum output power budget is 4700 W.

Caution

The PTX10003 DC power supply does not support an 60 A power source in Junos OS Evolved software release 19.1. When installing the PTX10003 DC power supply, be sure you set the input current selector to 80 A.

PTX10003 Input DC Voltage Specification

The PTX10003 DC power supply modules operate within the DC input voltage range listed in Table 6.

Note

Depending on the available input source, Juniper recommends that the 48-VDC facility DC source be equipped with a circuit breaker rated at a minimum of 60 A (-48 VDC) or 80 A (-48 VDC), or as required by local code.

PTX10003 DC Power Cables

You must supply the DC power cables that meet the specifications required by the local code, laws, and standards. The insulation color of the wires are color coded. Green is ground, black is line, and white is neutral. The wires are labeled (+) and (–) to indicate their polarity.

Caution

You must ensure that power connections maintain the proper polarity.

Warning

For field-wiring connections, use copper conductors only.

Warning

DC Power cables must not block access to PTX10003 components or drape where people could trip on them.

PTX10003 DC Power Lugs

The accessory box shipped with the PTX10003 includes the cable lugs that attach to the terminal studs of each power supply module. (The cable lug shown in Figure 9 is also used for grounding the chassis.) The cable lugs are dual hole and sized to fit 1/4-20 UNC terminal studs at 15.86-mm (0.625-in.) center line.

Figure 9: DC Power Cable Lugs
DC Power Cable Lugs
Caution

Before you begin to install the PTX10003, a licensed electrician must attach a cable lug to the power cables that you supply. A cable with an incorrectly attached lug can damage the PTX10003.
