•
INP1 into a UPS
•
INP2 into the public electricity supply
Each JNP10K-PWR-AC power supply has a power switch with international markings for on (|) and off

Figure 27: JNP10K-PWR-AC Power Supply
Each JNP10K-PWR-AC power supply comes with two power cord retainers that hold the power cords in
place. See Figure 28 on page 63 . Each power cord retainer has a clip and an adjustment nut. The ends of
the clip hook into the bracket holes on each side of the AC appliance inlet on the faceplate. The adjustment
nut holds the power cord in the correct position. For instructions for installing the power cord retainers,
see “Connecting AC Power to an MX10000” on page 163 .
NOTE: Route all the AC power supply cords away from the fan trays. Make sure that the power
cords do not obstruct the fan trays.
