ENTERASYS P0973BP Power Supply Module – Stable, Redundant AC Power for Enterasys Switches/Chassis

The ENTERASYS P0973BP is a field-replaceable AC power supply module designed for Enterasys networking platforms that specify the P0973BP PSU. From my experience, it’s typically used to enable redundancy (N+1) or to restore service quickly when a power module ages out. You might notice that it integrates cleanly with the chassis backplane, so there’s no extra cabling for DC distribution—just seat the module and the system handles the rest.

One thing I appreciate is the auto‑ranging input. In many cases, facilities power isn’t uniform across buildings, and this module generally deals well with 100–240 VAC environments without manual selection. For network teams who care about uptime, it seems to be a practical drop‑in that keeps spares simple and standard.

Order Placement Process and Guarantees

• Warranty: 365 days
• Delivery: 1 week if in stock; no more than one month at the latest
• Payment: 50% advance payment; full payment prior to delivery
• Express options: FedEx, UPS, DHL
• Packaging: ESD-safe bag + foam-protected carton, suitable for international transit

Key Features

• Auto‑ranging AC input (100–240 VAC, 50/60 Hz) – Typically accepts global mains power without switching, helpful for multi‑site rollouts.
• Backplane integration – Blind‑mate DC output to the chassis backplane; no external low‑voltage wiring required.
• Hot‑swappable design – In most supported chassis, a failed module can be replaced without a full system shutdown.
• Redundancy support – Enables N+1 or dual‑PSU configurations where the host system supports it, improving uptime.
• Protective circuitry – Over‑current, over‑voltage, and thermal safeguards are typically implemented to protect the load.
• Status indication – Front‑panel LEDs (varies by chassis) provide quick visual feedback on input and PSU health.
• Tool‑less latch/handles – Eases field replacement in tight network closets.

Technical Specifications

Application Fields

The P0973BP is commonly deployed in enterprise campus switches, distribution layers, and network closets where redundant power is preferred. It also fits neatly in small data centers, education networks, and healthcare facilities needing predictable uptime. One network manager at a university told us they swapped a P0973BP in under five minutes during a maintenance window—no service ticket spikes, no drama.

Advantages & Value

• Reliability – Built for continuous operation in wiring closets; protects the chassis with standard PSU safeguards.
• Compatibility – Intended for Enterasys platforms that specify P0973BP, reducing part number confusion.
• Cost control – Extends the useful life of legacy Enterasys switches without a full platform refresh.
• Serviceability – Hot‑swap capability (where supported) trims downtime and technician labor.
• Technical support – We can help verify fitment by device model and advise on redundancy configurations.

Installation & Maintenance

• Environment – Install in a standards‑compliant cabinet with front‑to‑rear airflow. Keep vents clear; allow at least 50 mm clearance.
• Power – Use a conditioned AC source (100–240 VAC). Where possible, feed redundant PSUs from separate PDUs/circuits.
• Wiring & ESD – Observe ESD precautions; if your chassis does not support hot‑swap, power down before removal.
• Checks – After insertion, confirm LED status and verify power redundancy in the chassis management UI/CLI.
• Routine care – Quarterly dust removal with dry air; annually verify PSU status logs. Firmware needs are typically on the chassis, not the PSU.
• Spare policy – For critical sites, keeping one P0973BP spare per location is a practical approach.

Quality & Certifications

• CE and RoHS compliance (typical for Enterasys PSU modules)
• UL/CSA safety marking on the unit label (varies by batch)
• Manufactured under ISO 9001 quality systems (supplier-level)
• Warranty: 365 days replacement guarantee

If you’d like, share your host device model and slot count—I can double‑check that the P0973BP is the right match and confirm lead time from the nearest warehouse.
