Use the cabling diagram to route power distribution unit (PDU) cables in Model 961 with eight I/O enclosures in single rack.
Figure 1. Locations for power distribution
units
Figure 2. Locations for power distribution unit (PDU) connectors
Table 1 shows
power cables between the power distribution units (PDUs) and the DC
uninterruptible power supplies (DC-UPSs).
Table 2 shows
power cables between the PDUs and the CEC enclosure, I/O enclosure,
HMC, Ethernet, and storage enclosure power supplies.
Table 3, Table 4,
and Table 5 show
power cables between the PDUs and the CEC enclosure, I/O enclosure,
management console (20V), Ethernet switch and fan tray (12V), and
storage enclosure power supplies.
