PTX10002-60C Power System

PTX10002-60C AC Power Supply Description

The AC power supplies in the PTX10002-60C (see Figure 1 and Figure 2) are hot-removable, and hot-insertable field-replaceable units (FRUs) that you can install without powering off the router or disrupting the routing function. The PTX10002-60C has four power supplies. All the power supplies are initially installed at the factory.

CAUTION:

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

Each of the 1600-W power supplies has a single AC input. The power supply provides 12-VDC output with a standby voltage of 12 VDC. A PTX10002-60C provides for twice the number of power supplies needed to power all of the components in the device, which is known as 2N redundancy. When the PTX10002-60C has all four power supplies installed and connected to power, the router has full power redundancy. If a power supply fails or is removed, another power supply balances the electrical load without interruption.

Note:

For more information about power system redundancy, see PTX10002-60C Component Redundancy.

The fan in the power supply provides port-to-FRU airflow, which is also known as airflow out (AFO). A power supply with the label AFO or a gold-colored handle denotes port-to-FRU airflow.

PTX10002-60C DC Power Supply Description

The DC power supplies in the PTX10002-60C (see Figure 3 and Figure 4) are hot-removable and hot-insertable field-replaceable units (FRUs) that you can install without powering off the router or disrupting the routing function. The PTX10002-60C has four power supplies. All the power supplies are initially installed at the factory.

CAUTION:

To avoid electrical injury, carefully follow instructions in Maintaining the PTX10002-60C Power Supplies.

Note:

We recommend that the 48-VDC facility DC source be equipped with a circuit breaker rated at 40 A (–48 VDC) minimum, or as required by local code.

PTX10002-60C Power Supply LED

Each PTX10002-60C power supply has a status LED on the power supply faceplate. Figure 5 shows the location of the LED on a PTX10002-60C AC power supply and Figure 6 shows the location of the LED on a PTX10002-60C DC power supply.

Either the power cord is unplugged or a major error is detected in the power supply. Examples of a major error are: power supply failure, an over voltage protection error, an over current protection error, or a fan failure.

  • If the power cord is unplugged or missing, reattach the power cord appropriate for your country.

  • If a major error is occurring, Replace the power supply as soon as possible. To maintain proper airflow through the chassis, leave the power supply installed in the chassis until you are ready to replace it.

PTX10002-60C AC Power Cord Specifications

Detachable AC power cords are shipped with the chassis if you include them as part of your order. The coupler is type C13 as described by International Electrotechnical Commission (IEC) standard 60320. The plug end of the power cord fits into the power source outlet that is standard for your geographical location.

Note:

In North America, AC power cords must not exceed 14.75 feet (approximately 4.5 meters) in length, to comply with National Electrical Code (NEC) Sections 400-8 (NFPA 75, 5-2.2) and 210-52 and Canadian Electrical Code (CEC) Section 4-010(3). The cords that can be ordered for the PTX10002-60C are in compliance.

Note:

The optional right-angle DC power cables, CBL-JNP-PWR-DSUB2 and CBL-JNP-PWR-DSUB3, do not include a ground connection wire.

Regardless which DC power cable you use, you must connect the PTX10002-60C to earth ground before you connect it to power, using the procedure described in Connecting the PTX10002-60C to Ground.

Warning:

For field-wiring connections, use copper conductors only.

Warning:

Power cables must not block access to PTX10002-60C components or drape where people could trip over them.

CAUTION:

You must ensure that power connections maintain the proper polarity. The power source cables might be labeled (+) and (–) to indicate their polarity. There is no standard color coding for DC power cables. The color coding used by the external DC power source at your site might be different from the color coding for the leads on the DC power cable provided with the chassis.
