Alcatel Lucent ESX-K100C32W4 Power Supply Module

The Alcatel Lucent ESX‑K100C32W4 (also designated ESXK100C32W4) is a high‑capacity power supply module engineered for use in Alcatel Lucent’s OmniSwitch series chassis and other compatible systems. This unit delivers stable, regulated DC power to all active components, ensuring uninterrupted operation even under heavy load conditions. With its efficient design, intelligent protection features, and hot‑swappable form factor, the ESX‑K100C32W4 is a reliable choice for enterprise and service provider network environments.

Overview

The ESX‑K100C32W4 is a front‑accessible, modular power supply that fits into designated power bays of the chassis. It accepts a wide range of AC input voltages and provides a single high‑current DC output to the system backplane. The module incorporates active power factor correction (PFC) to minimize harmonic distortion and improve overall energy efficiency. It is designed to operate in N+1 or N+N redundancy configurations, allowing multiple units to share load and provide backup in case of a unit failure.

Key Features

• Output power: 1000 W continuous (at 48 VDC)

• Universal AC input: 100‑240 VAC, 47‑63 Hz, with active PFC

• High efficiency > 90% at typical load

• Hot‑swappable and tool‑less installation

• Built‑in over‑voltage, over‑current, over‑temperature, and short‑circuit protection

• LED indicators for power status, fault, and thermal warning

• Internal cooling fan with speed control based on temperature

• I²C interface for remote monitoring of voltage, current, and temperature

Technical Specifications

• Input Range: 100‑240 VAC (auto‑sensing), 47‑63 Hz

• Input Current: 12 A maximum at 100 VAC

• Output Voltage: +48 VDC (nominal), adjustable ±5%

• Output Current: 20.8 A continuous

• Ripple & Noise: < 100 mV peak‑to‑peak

• Hold‑up Time: > 20 ms at full load

• MTBF: > 300,000 hours at 25°C

• Dimensions: 86 mm (H) × 220 mm (W) × 300 mm (D)

• Weight: 3.2 kg

Applications

This power module is primarily used in OmniSwitch 6850, 9000, and 10000 series chassis, as well as in Alcatel Lucent transport and routing platforms that share the same power interface. It is suitable for data center environments, campus networks, and central office installations where high reliability and power redundancy are required.

Integration and Management

The ESX‑K100C32W4 communicates with the host system via an I²C bus, providing real‑time telemetry to the chassis management controller. Network administrators can monitor input voltage, output current, module temperature, and fan speed through the system CLI or SNMP. The module also supports firmware upgrades over the management interface to improve performance or add features.

Installation and Maintenance

Installation is simple: slide the module into an empty power bay until it clicks into place, then secure the locking mechanism. The module automatically starts when the chassis is powered on. Maintenance involves periodic inspection of the air intake filter (if equipped), verifying fan operation, and checking the LED status. If a fault is detected, the module can be replaced without powering down the chassis, thanks to its hot‑swap capability.

Conclusion

The Alcatel Lucent ESX‑K100C32W4 power supply module delivers high power density, excellent efficiency, and robust protection in a compact package. Its integration with Alcatel Lucent management systems and redundancy support makes it an essential building block for resilient network infrastructures.
