ENTERASYS C2RPS-PSM | Redundant Power Supply Spec Sheet
Product Introduction
When an enterprise distribution switch loses a power supply during a peak data traffic window, the resulting network drop can isolate entire building wings in seconds. The Enterasys C2RPS-PSM is not a standard desktop power brick; it is a heavy-duty modular power supply engineered specifically to slide into the rear bay of C2-series network switch chassis for uninterrupted redundancy.
Seated securely in the backplane power slot, the unit converts building AC power into clean, regulated DC voltage rails—keeping core switching logic alive even if the primary internal power supply fails. It demands a stable rack power feed and proper ventilation clearance, but once locked into the chassis bay, it delivers the dependable uptime required for mission-critical IT infrastructure.

Application Scenarios & Pain Points
- Enterprise Telecom Closets: Aging power distribution units used to suffer from capacitor dry-out, causing random switch reboots during high-load periods. Swapping in the Enterasys C2RPS-PSM restored true power redundancy and eliminated unexpected downtime.
- Campus Core Distribution Nodes: Without a secondary power source, a single blown fuse would knock out VLAN routing across an entire floor. This C2RPS-PSM module provides seamless failover support.
- Legacy Hardware Maintenance: An IT team avoided an expensive, full-scale switch stack replacement by sourcing a verified surplus C2RPS-PSM unit to revive a failed power bay instantly.
QA & Live Testing SOP (Trust Signal)
Surplus networking hardware demands rigorous verification before installation. Every incoming Enterasys C2RPS-PSM goes through a strict multi-point test protocol:
- Visual & Component Inspection: We check internal electrolytic capacitors for bulging, examine power pins for oxidation, and verify cooling fan bearing health.
- Powered Bench Verification: The module is slotted into a live C2-series test chassis, energized with standard AC voltage, and subjected to a simulated full-load power draw test to verify rail stability.
- ESD-Safe Packaging: Units are sealed in heavy-duty antistatic bags. When you unbox the , it is ready for immediate deployment in your server rack.
Field Engineer’s Pitfall Guide
- ❗ AC Circuit Overloading: Never plug multiple redundant power modules into a single, daisy-chained power strip without verifying total branch circuit ampacity to avoid tripping upstream breakers.
- ❗ Fan Airflow Obstructions: Ensure the rear exhaust vents on the are never blocked by cable management arms or rack doors, or thermal throttling will trigger premature shutdowns.
- ❗ Mismatched Firmware/Hardware Revisions: Always verify that your switch chassis backplane can support the specific revision level of the replacement power module before hot-swapping.
Intent-Driven FAQ
Can I hot-swap the Enterasys while the network switch is running?
Yes. Provided the switch chassis is operating with an active primary power supply or redundant second module, the is fully hot-swappable.
Is this specific unit brand new or refurbished?
This inventory consists of verified surplus—un-installed factory backup stock preserved in climate-controlled storage facilities.
What kind of power cord does this module require?
It uses a standard IEC C13/C14 power cable matching standard server rack power distribution units (PDUs).
What warranty comes with this purchase?
Every surplus includes a standard 1-year replacement warranty covering any functional defects under normal operating conditions.
Do I need to configure software settings when installing this power supply?
No software configuration is required; the switch chassis will automatically detect the presence of the and update its power status via SNMP/CLI logs.
