Hardware Compatibility

Important Notes:

1. This PSU supports both system power delivery and PoE supply, unlike the data-only PWR-C45-1000AC.
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 modular switch platforms.
4. Minimum required firmware: Cisco IOS 12.1(12c)EW or CATOS 7.4(1)
   Matching secondary redundant variant:PWR-C45-1300AC/2.

Key Features & Benefits

1. Hot-swappable OIR capability: Allows live PSU replacement without complete chassis power shutdown to reduce maintenance downtime.
2. Wide universal AC input supports global deployment across international power grid standards.
3. Dual power operating modes: redundant mode or combined load-sharing mode for flexible power budget planning.
4. Native IEEE 802.3af PoE support to power IP phones, wireless access points and IP surveillance cameras connected to PoE line cards.
5. Real-time power status monitoring, fault logging and alert reporting via Cisco IOS CLI and SNMP.
6. High power factor correction (PFC) design improves energy efficiency and reduces power harmonic interference.
7. Carrier-grade robust hardware designed for stable long-term continuous operation in data center and equipment room environments.

Compliance & Certification

Important Note

PWR-C45-1300AC = primary 1300W AC power supply (Supports system power + PoE)

PWR-C45-1300AC/2 = secondary redundant AC variant with identical electrical and mechanical specifications for dual redundant configurations.
