PTX1000 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 PTX1000
to earth ground before you connect it to to power, using the procedure
described in "Connecting the PTX1000 to Ground" on page
DC power cables, each approximately 13.1 ft (4 m) long, are supplied with the PTX1000.
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 16 on page 42 lists the specifications for the PTX1000 DC power cables.
