Connections and Cables
HP provided facility DC cable connection kit:
The facility DC connection kit supports the connection of up to four -48VDC,
RETURN pairs and ground
RETURN pairs and ground
The power cable assemblies consist of 1/0AWG, color-coded, flexible cable rated at
105° C, terminated with bus mating connectors at one end and unterminated at the
other end. The cable length provided enables the customer to route to a fuse panel
within or adjacent to the rack.

NOTE: *All systems support redundant A and B feeds. Scalable bus bars support dual A and dual B feeds.
** Periodic and random noise (PARD). Maximum allowable peak-to-peak ripple and noise (as measured at the load on
any output channel). The ripple and noise is measured over a 20 Hz to 100 MHz frequency band. A resistive load
(non-electronic) is used for this measurement. Each output is by-passed to return by a 10uF tantalum capacitor with
an ESR less than 100 milli-Ohms in parallel with a 0.47 uF ceramic capacitor, at the point of load. The load cable is 12
feet of twisted wire capable of carrying the current. The printed wiring board assembly is installed in its enclosure
for this measurement, or the measurement leads are properly shielded with Earth grounds applied to the insert.
