The Cisco PWR-C5-1KWAC (OEM model DPS-1000AB-5 A by Delta Electronics) is a 1000 Watt hot-swappable AC power supply designed for the Cisco Catalyst 9200 and 9300 Series switches. It provides high-efficiency power conversion and redundancy support in enterprise campus and data center environments.

This is a 1kW AC power module that delivers reliable, efficient power to Catalyst 9300 and 9200 stackable switches. It supports full PoE/PoE+ / UPOE budgets when used in pairs and features high efficiency (80 PLUS Platinum rated) with active PFC. The PWR-C5-1KWAC is hot-pluggable, allowing replacement without shutting down the switch when installed in redundant configurations.

Model / Part Number: Emerson 74Y5903

Designation: VRM-PROC-CJ (Processor Voltage Regulator Module – CJ variant)

CCIN: 2BC7

Primary Systems: IBM Power 770 (9117-MMB / 9117-MMC) and Power 780 (9179-MHB / 9179-MHC)

Function: Voltage regulation for POWER7 processor cores and associated logic in the CEC (Central Electronics Complex)

Installation Location: Specific slot on the processor book (CPU book / processor card)

Hot-Swap: No – requires power-down of the CEC (or failover in redundant CEC setups)

Status (2025–2026): Legacy / End-of-Life – POWER7 systems reached EoL/EoS over a decade ago; no new production or active IBM support

Market Availability: Refurbished or used pulls from decommissioned Power 770/780 systems

Common Sources: eBay, IBM surplus resellers, enterprise hardware brokers (Vibrant Technologies, ServerMonkey, ITAssetRecovery)

Typical Price Range: $80–$250 (refurbished, depending on condition and testing)

Type: DC-DC voltage regulator module (VRM)

Function: Steps down bulk power to low-voltage rails for POWER7 SCMs (Single-Chip Modules)

Output: High-current, tightly regulated low-voltage rails (typically 0.9V–1.2V range for processor cores)

Protection: Over-current, over-voltage, over-temperature, short-circuit

Redundancy: Supports N+1 or N+N configurations (multiple VRMs per processor book)

Hot-Swap: No (major FRU – system power-down required)

Status Indicators: LED indicators for power/fault status (visible on the processor book)

Monitoring: Via HMC (Hardware Management Console), ASMI, and system firmware

Form Factor: Plug-in module for POWER7 processor book

Power Requirements: Supplied by CEC bulk power distribution
