Cisco PWR-C45-1000AC
Catalyst 4500 1000W AC Power Supply (Data Only)
Product Highlights
What's Included
Keeping your Cisco Catalyst 4500 Series chassis powered reliably is non-negotiable — an unexpected power supply failure can take down an entire campus access or distribution layer. The Cisco PWR-C45-1000AC is a 1000-watt AC power supply purpose-built for data-only configurations in the Catalyst 4500 and 4500 E-Series switch families.
Designed for universal deployment, this power supply accepts 100–240V AC input at 50/60 Hz, eliminating the need for external voltage converters in global installations. Its hot-swappable form factor allows field replacement or addition of a redundant PSU without disrupting network traffic — critical for environments where uptime is paramount.
With a mean time between failures (MTBF) of 250,000 hours and integrated fan cooling rated at 943 BTU/h heat dissipation, the PWR-C45-1000AC is engineered for sustained, heavy-duty operation in enterprise wiring closets and data center environments. SNMP MIB support enables remote health monitoring, giving network operations teams real-time visibility into power supply status. Each unit ships with an AC power cord, so you can install and power up immediately.
Note: This is a data-only power supply and does not provide inline PoE power. For deployments requiring Power over Ethernet, consider a Catalyst 4500 PoE-capable power supply such as the PWR-C45-1300ACV.
Features & Benefits
Data-Only 1000W AC Power
The PWR-C45-1000AC delivers 1000 watts of clean AC-to-DC power optimized for data-only switch configurations. This makes it an ideal, cost-effective choice for Catalyst 4500 deployments where Power over Ethernet is not required — such as uplink aggregation or core distribution roles.
Hot-Swappable Redundancy
Designed for hot-swap installation, this power supply can be inserted or removed from a live Catalyst 4500 chassis without interrupting network operations. Pair two units in a 1+1 redundant configuration to ensure continuous power delivery even if one supply fails — a must for mission-critical campus networks.
Universal AC Input
Operating across a 100–240V AC input range at 50/60 Hz with a maximum input current of 12A, the PWR-C45-1000AC supports worldwide deployment without external step-down or step-up transformers. This simplifies procurement and standardizes your spare-parts inventory across global sites.
Enterprise-Grade Reliability
With a rated MTBF of 250,000 hours, integrated fan cooling, and 943 BTU/h heat dissipation, this power supply is built for 24/7 operation in demanding environments. A 20 ms holdup time protects against brief power interruptions, while SNMP MIB support enables proactive remote monitoring.
Deployment Scenarios
Campus Access & Distribution Layer
Power a Catalyst 4500 or 4500 E-Series chassis serving as a campus access or distribution switch. The 1000W data-only supply is well-suited for deployments where line cards carry data traffic without PoE requirements, keeping power costs and thermal output lower than higher-wattage PoE supplies.
Redundant Power Supply Upgrade
Add a second PWR-C45-1000AC to an existing Catalyst 4500 chassis to achieve 1+1 power redundancy. Hot-swap capability means you can install the redundant supply during production hours without scheduling a maintenance window.
Spare / Rapid Replacement Inventory
Stock the PWR-C45-1000AC as a pre-positioned spare for multi-site Catalyst 4500 deployments. Its universal input voltage and included AC power cord mean a field technician can swap a failed unit and restore service in minutes.

Important Notes
- This is a data-only power supply. It does not support Power over Ethernet (PoE) or inline power.
- For PoE deployments, use the PWR-C45-1300ACV (1300W) or higher-wattage PoE supplies.
- AC power cords use an IEC 60320/C15 appliance connector at the equipment end.
