This configuration requires "Y" power cables for the chassis power supplies. Part
numbers are listed in Table 5-1.
Table 5-1 Y cable part numbers
Part number Description
00Y3046 1.345 m, 2x C13 to C14 Jumper Cord, Rack Power Cable
00Y3047 2.054 m, 2x C13 to C14 Jumper Cord, Rack Power Cable
Figure 5-2 on page 120 shows the connections from four 1U PDUs. Each PDU
has 12 outlets; thus, 48 outlets are available. There are six NeXtScale n1200
Enclosures, each with six power supplies, so there are 36 power supplies to be
connected. This means that there are 12 outlets that are not connected to
chassis.
