PTX10001 Power System

 

PTX10001 AC Power Supply Description

The two power supplies in a PTX10001 are hot-removable and hot-insertable field-replaceable units (FRUs). The power supplies are installed in the device at the factory. You can install replacement power supplies from the management panel without powering off the device or disrupting the devices functions.

The AC power supply is 850 W. Figure 1 shows the location of the power supplies on the FRU end of the device. Figure 2 shows an example of the AC power supply. The PTX10001 has two power supplies.

Caution

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

When the PTX10001 has both power supplies installed and connected to power, the device has full power redundancy. If a power supply fails or is removed, another power supply balances the electrical load without interruption.

Caution

To avoid electrical injury, carefully follow instructions in Connecting the PTX10001 to Power, Maintaining the PTX10001 Power Supplies.

On steadily

An error has been detected in the power supply. 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.

Note

If the AC LED and the DC LED are unlit, either the AC power cord is not installed properly or the power supply fuse has failed. If the AC LED is lit and the DC LED is unlit, the AC power supply is installed properly, but the power supply has an internal failure.

PTX10001 DC Power Supply Description

The power supplies in PTX100001 devices (see Figure 4)are hot-removable and hot-insertable field-replaceable units (FRUs) that you can install in a PTX10001 device without powering off the device or disrupting the routing functions.

The DC power supply is 850 W with dual feeds for power resiliency.

Caution

The V+ terminals are shunted internally together, as are the V- terminals. The same polarity terminal can be wired together from the same source to provide an additional current path in a higher power chassis. Do not connect the terminals to different sources.

PTX10001 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 at the male 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).

PTX10001 DC Power Cable Specifications

PTX10001 DC power supplies require a D-Sub 3W3- type connector. The three pins on the connector provide –48 VDC input (–), return (+), and ground connections to the power supply.

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 PTX10001 to earth ground before you connect it to to power, using the procedure described in Connecting the PTX10001 to Ground.

DC power cables, each approximately 13.1 ft (4 m) long, are supplied with the PTX10001. The provided cables include the three-pin connector on one end and insulated wires at the opposite end, for connection to the site’s DC power distribution system.

Table 6 lists the specifications for the PTX10001 DC power cables.

Warning

Warning

Power cables must not block access to PTX10001 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.
