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

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.
The DC power supply has four terminals labeled V-, V-, V+, and V+ (see Figure 5 for connecting DC power source cables labeled positive (+) and negative (–).

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.
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.
Table 6: PTX10001 DC Power Cable Specifications
For field-wiring connections, use copper conductors only.
Power cables must not block access to PTX10001 components or drape where people could trip over them.
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.
