PTX10001-36MR Power System

The PTX10001-36MR is powered by 3000-W redundant AC/HDVC or DC power supplies that are preinstalled at the factory. The PTX10001-36MR 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 VAC

  • HDVC input voltage range: 204-380 VDC

  • DC input voltage range: -40 VDC Minimum, -72 VDC maximum

CAUTION:

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

PTX10001-36MR 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 of power to the system.

Figure 1 shows the location of the power supplies on the back panel.

PTX10001-36MR DC Input Current Selector (DIP Switch)

The PTX10001-36MR 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. Refer to Figure 4 for the location of the DIP switch. 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:

Input Current

Description

60 A

The power supply module limits the output power to 2200 W when the input voltage is between 40 V and 48 V. 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 48 V and 72 V.

80 A

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

PTX10001-36MR Input DC Voltage Specification

The PTX10001-36MR DC power supply modules operate within the DC input voltage range listed in Table 8. The PTX10001-36MR DC power consumption is listed in Table 9.

Note:

Depending on the available input source, we recommend 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 10 shows system behavior in different scenarios with 60 A DC power supply modules.

Table 10: System Behavior in Different Scenarios with 60-A DC power supply modules

Input voltage: < 40 V

Input voltage: 40 V to 72 V

60 A DC mode

The power supply module is powered off and won’t turn on when the system is powering up.

Normal operation.

The power supply modules are offline and the system is powered down.

Normal operation.

PTX10001-36MR with one power supply modules

The power supply modules are offline and the system is powered down.

Normal operation, but there’s no power supply module redundancy.

In all these 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.

PTX10001-36MR DC Power Cables

You must supply the DC power cables that meet the specifications required by the local code, laws, and standards. The insulation for the wires in the cables is 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 PTX10001-36MR components or drape where people could trip on them.

PTX10001-36MR DC Power Lugs

The accessory box shipped with the PTX10001-36MR includes the cable lugs that attach to the terminal studs of each power supply module. (The cable lug shown in Figure 6 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 6: DC Power Cable LugsDC Power Cable Lugs
CAUTION:

Before you begin to install the PTX10001-36MR, 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 PTX10001-36MR.
