Power Supplies
The QFX10000 switches support AC, DC, high-voltage alternating current (HVAC) and high-voltage
direct current (HVDC) by offering the following power supplies:
• QFX10000-PWR-AC
• JNP10K-PWR-AC2
• QFX10000-PWR-DC
• JNP10K-PWR-DC2
All of the power supplies for the QFX10000 are fully redundant, load-sharing, and hot-removable and
hot-insertable FRUs. Each QFX10016 base configuration has five power supplies; redundant
configurations hold the maximum of ten AC HVAC, DC, or HVDC power supplies. Each power supply
has an internal fan for cooling. You can install the power supplies in any slot. See
Table 2 on page 14
and Figure 10 on page 16 through Figure 13 on page 17 .
The JNP10K-PWR-AC2 and JNP10K-PWR-DC2 PSMs work optimally with the enhanced power bus. To
determine whether your system has the standard power bus or the enhanced power bus, see
"QFX10000 Status Panel" on page 26 . Table 2 on page 14 provides the specifications for these
different power supplies.
