The PTX10001-36MR is powered by 3000-W redundant AC/HDVC or DC power supplies that are
preinstalled at the factory. The PTX10001-36MR is powered by two power supplies for 1 + 1
redundancy. The power supplies are hot-removable and hot-insertable. If one power supply fails, you
can replace it without powering o or disrupng the roung funcon. The other power supply balances
the electrical load without interrupon. Each power supply has two outputs: 12 V and 12 V standby.
Two counter-rotang fans in each power supply provide front to back cooling. The input voltages are as
follows:
• AC input voltage range: 200-277 VAC
• HDVC input voltage range: 204-380 VDC
• DC input voltage range: -40 VDC Minimum, -72 VDC maximum
