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 module fails, you can replace it without powering off or disrupting the routing function. The other power supply module balances the electrical load without interruption. Each power supply module has two outputs: 12 V and 12 V standby. Two counter-rotating fans in each power supply module 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
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.

The insulation color for wires in the HVDC cables are color coded. Green is ground, black is line, and white is neutral. For HVDC, the black and white wires are not polarity-sensitive. The black wire can be positive (+) or neutral (–) and the white wire can be positive (+) or negative (–).
PTX10003 DC Power Supply Description
The PTX10003 DC power supplies are hot-removable and hot-insertable FRUs. Each 3000 W power supply module has a single DC input and provides 12 VDC output with a standby voltage of 12 VDC. The PTX10003 DC power supplies can operate with an input current of 80 A or 60 A.
Support for a 60 A power source was added in Junos OS Evolved Release 19.4. If you are using an earlier release, you’ll need to use an 80 A power source. Be sure you set the DIP switch to 80 A when installing the PTX10003 DC power supply module.
Figure 5 shows the location of the DC power supplies on the PTX10003-160C FRU panel, and Figure 6 shows the location of the DC power supplies on the PTX10003-80C FRU panel.

PTX10003 DC Input Current Selector (DIP Switch)
The PTX10003 DC power supply module 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. If you select 60 A, the power supply module 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 module limits the output power so that the input current does not exceed 80 A.
For example:
If you select... |
Then... |
|---|---|
60 A |
The power supply module limits the output power to 2200 W when the input voltage is between 40V and 48V. It linearly increases the output power if the input voltage increases. The power supply module provides 2700 W output power when the input voltage is between 48V and 72V. |
80 A |
The power supply module provides 3000 W output power throughout the input voltage range from 40 VDC to 72 VDC. |
PTX10003 Input DC Voltage Specification
The PTX10003 DC power supply modules operate within the DC input voltage range listed in Table 7.
Support for a 60 A power source was added in Junos OS Evolved Release 19.4. If you are using an earlier release, you’ll need to use an 80 A power source. Be sure you set the DIP switch to 80 A when installing the PTX10003 DC power supply module.
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.

60 A Input Feed Power Management
The 60 A DC power supply module capacity changes when the input voltage is below or above the under voltage limit as follows:
When the 60 A DC power supply module input voltage is above the input under voltage warning limit, its capacity is 2700 W.
When the input voltage is below the input under voltage warning limit, the power supply module capacity is reduced to 2200 W.
When the input voltage is above the input under voltage warning limit, the software adjusts the system capacity and reallocates power to the FRUs based on the new system capacity. Table 8 shows system behavior in different scenarios with 60 A DC power supply modules.
Input voltage: < 40V |
Input voltage: > 40V and < 48V |
Input voltage: 48V to 72V |

Power off FPC1, FPC2,and FPC3, and keep FPC0 online. There’s no power supply module redundancy. |
The worst case scenario is when all power supply module inputs
are at the same voltage level. It’s possible that FPC1, FPC2,
or FPC3 of the four power supply modules are operating in a reduced
capacity and the rest of the power supply modules are operating at
a normal capacity. In all those scenarios, power management actions
can be different but deterministic based on the total system capacity
and total system power required. Use the show chassis power detail command to determine the behavior.
PTX10003 DC Power Cables
You must supply the DC power cables that meet the specifications required by the local code, laws, and standards. You must connect the power supply terminal marked (-48) to -48V or +48V RTN, and the terminal marked (RTN) to -48V RTN or +48V.
You must ensure that power connections maintain the proper polarity.
For field-wiring connections, use copper conductors only.
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.
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.
