Power supply HP ProCurve ZL 875W PS 875W for networking equipment, model RP001235651

Replacement power supply compatible with HP ProCurve ZL series networking equipment, providing 875 watts of continuous output to support switches and related devices. Engineered to deliver stable voltage and sufficient current for mid- to high-density network modules, this 875W unit is intended as a field-replaceable module for maintenance, upgrades, or spare-part inventory. The design supports sustained operation in standard rack environments and helps maintain system availability by restoring power capability quickly when a primary unit fails or when additional capacity is required.

Advantages

The power supply offers consistent 875W output with thermal and electrical protections to guard against overload and over-temperature conditions. Its form factor and connector layout are compatible with ZL-series chassis, enabling straightforward installation and hot-swap replacement where supported by the host device. The unit reduces the need for extended downtime during repairs by allowing technicians to replace or upgrade power capacity without lengthy system disassembly. Built to industry power quality standards, it contributes to reliable network operation and predictable performance under typical load profiles.

Suitable for

• Replacing a failed or degraded PSU in HP ProCurve ZL-series switches
• Maintaining redundant power configurations in network racks
• Stocking as a spare part for IT maintenance teams
• Upgrading power capacity for additional line cards or modules

Key specifications

• Rated output power: 875 watts continuous
• Compatibility: designed for HP ProCurve ZL-series networking chassis
• Cooling: integrated fan-assisted thermal management
• Protection features: overcurrent and overtemperature protection
• Form factor: field-replaceable module for compatible switch chassis
• Input type: AC mains input (typical for enterprise network PSUs)

How to use

Before installation, power down the host device or follow the vendor-recommended hot-swap procedure if the chassis supports live replacement. Verify that the replacement unit is compatible with the specific ZL-series model and that the rack or cabinet provides adequate ventilation. Remove the failed power supply module according to the equipment manual, then insert the replacement until it seats and the retention mechanism engages. Restore AC power and confirm that the system reports the new unit as present and functional through the device management interface and LED indicators.

Usage recommendations

Keep replacement units in a dry, dust-free environment and handle them using proper electrostatic discharge (ESD) precautions. When using multiple power supplies for redundancy, ensure balanced loading across units and monitor temperature and fan operation during high-load periods. Follow the host device documentation for firmware and compatibility notes before deploying the module in production.
