Cisco NXA-PDC-2KW-PI Full English Description

Product Overview

Important Note: This power supply does NOT include DC power cable; accessory cablePWR-2KW-DC-CBLmust be ordered separately.

Key Features

1. 2000 Watt Continuous Rated Output
   Delivers maximum 2000W 12VDC continuous power output with additional 36W standby power. Supports 1+1 redundant configuration and dynamic load sharing, eliminating single-point power failure risks for mission-critical data center networks.
2. Telecom Negative Wide DC Input Range
   Designed for standard telecom negative DC power systems:

• Input Voltage Range: -40 VDC ~ -72 VDC (nominal -48 VDC ~ -60 VDC)
• Terminal interface for telecom -48V DC power feeds

1. Port-Side Intake (Reverse Airflow / Front-to-Back Airflow)
   Air enters the switch from port side and exhausts out of fabric side.
   Important Note: All power supplies and fan trays installed within one chassis must adopt identical airflow direction. Do NOT mix PI (port-side intake) and PE (port-side exhaust) modules. AC and DC power supplies cannot be mixed inside the same switch chassis.
2. Hot-Swap FRU Architecture
   Supports online insertion and removal. Technicians can replace defective power modules without shutting down the host switch, enabling non-disruptive hardware maintenance.
3. Real-Time Telemetry & LED Status Indication
   Front-panel LED indicators display DC input status and operational health. The module transmits temperature, voltage and fault alarm data to the NX-OS operating system via chassis backplane.
4. Multi-Layer Hardware Protection
   Built-in overvoltage protection (OVP), overcurrent protection (OCP), overtemperature protection (OTP) and short-circuit protection to safeguard both the power supply and host switch hardware.
5. High Power Conversion Efficiency
   Maintains ≥90% energy efficiency between 20% and 100% operating load, minimizing power loss and thermal generation to reduce cooling expenditure for large-scale carrier and data center facilities.
