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.
QFX10002 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 QFX10002
to earch ground before you connect it to power, using the procedure described
in "Connecting the QFX10002 to Ground" on page
DC power cables, each 4 m (approximately 13.1 ft) long, are supplied with the QFX10002.
The provided cables include the three-pin connector on one end and three insulated
wires at the opposite end, for connection to the site's DC power distribution system.
Table 26 on page 60 lists the specifications for the QFX10002 DC power cables.
