Hardware Compatibility

Important Restrictions:

1. This PSU supplies system data power only. It cannot provide IEEE 802.3af PoE power. Select PWR-C45-1400DC-P for chassis requiring PoE capability.
2. Vacant power supply slots must be equipped with official Cisco filler panels to guarantee proper chassis airflow, thermal balance and EMC compliance.
3. Not compatible with Catalyst 9000, Catalyst 3850 or other non-C4500-E modular switch platforms.
4. Cisco recommends deploying identical PSU variants for redundant configurations; mixed installation of standard DC and TT-version power supplies is physically supported but not recommended.
   Matching secondary redundant variant:PWR-C45-1400DC-TT/2.

Key Features & Benefits

1. Hot-swappable OIR capability: Enables live PSU replacement without full chassis power shutdown to reduce maintenance downtime.
2. Telecom optimized TT terminal connector design, convenient for standard service provider DC power cabinet wiring.
3. Wide-range negative DC input, tailored for carrier central offices, transportation and industrial sites equipped with -48V DC battery power systems.
4. Supports load-sharing 1+1 redundant power mode for mission-critical carrier and enterprise core switching infrastructure.
5. Optimized high-capacity non-PoE DC power solution for data-only chassis deployments to control hardware investment costs.
6. Real-time power health monitoring, fault logging and status reporting via Cisco IOS CLI and SNMP.
7. Robust carrier-grade hardware design for long-term stable continuous operation in central offices and equipment rooms.

Typical Deployment Scenarios

Compliance & Certification

Important Note

PWR-C45-1400DC-TT = primary 1400W DC data-only power supply (TT terminal variant)

PWR-C45-1400DC-TT/2 = secondary redundant DC variant with identical electrical and mechanical specifications for dual redundant setups.

This is DC-input module; do not connect directly to commercial AC mains.
