Cisco NXA-PDC-1100W-PI Full English Description

Product Overview

Key Features

1. 1100 Watt Continuous Rated Output
   Delivers maximum 1100W 12VDC power output. Supports 1+1 redundant deployment and dynamic load sharing, eliminating single-point power failure risks for mission-critical network operations.
2. Telecom Negative DC Wide Input Range
   Engineered for standard telecom DC power systems:

• Input Voltage Range: -40 VDC ~ -72 VDC (nominal -48 VDC / -54 VDC)
• Maximum Input Current: 32 A @ -40 VDC
• Terminal connection for negative DC telecom power feeds

1. Port-Side Intake (Reverse Airflow / Front-to-Back Airflow)
   Air flows into the switch from port side and exhausts outward from fabric side.
   Important Note: All power supplies and fan trays 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. 80 PLUS Platinum High Efficiency
   Up to 94% efficiency at 50% rated load, minimizing power loss and heat generation to reduce cooling costs for large-scale carrier and data center sites.
