Description
Product Introduction
The Enterasys C2RPS-CHAS2 (Extreme Networks) is a 2-slot redundant power supply chassis engineered to deliver centralized power fault tolerance for Enterasys enterprise switches and industrial networking equipment. Designed to hold up to two plug-in power supply modules (such as the C2RPS-PSU), the C2RPS-CHAS2 acts as an external power distribution frame that ensures mission-critical network nodes stay online even during a primary internal power supply failure.
Built with a rugged metal enclosure, the C2RPS-CHAS2 routes DC power directly to target switches via dedicated cable harnesses. By offloading thermal and electrical stress from the primary switch chassis, this external RPS chassis significantly extends network hardware longevity and provides the power redundancy required in high-uptime industrial manufacturing, utility, and enterprise infrastructure deployments.

Application Scenarios & The “Trench” Experience
In a continuous process plant, losing a core distribution switch due to a popped internal power supply shuts down the entire SCADA monitoring network. To be honest, I’ve had to diagnose a line stoppage at 2 AM where a single point of power failure dropped an entire stack of industrial Ethernet switches. Installing a C2RPS-CHAS2 with dual power modules provides instant hitless failover—if a utility leg dies or a power module short-circuits, the secondary supply carries the load seamlessly without dropping a single packet.
- Industrial Plant Control Networks – Redundant Ethernet Switch Power – Ensures SCADA and PLC communication switches remain energized during facility power glitches.
- Data Centers & Server Rooms – Secondary DC Power Backup – Delivers dual-bus power safety for edge-of-rack switches and patch panels.
- Critical Infrastructure & Utilities – Continuous Network Uptime – Prevents network blackout events during localized AC supply failures.
- Legacy Control Cabinet Maintenance – Drop-In Replacement – Allows quick swap-outs of damaged RPS frames without requiring rack re-cabling.

Transparency SOP: Quality Assurance & Testing
We don’t just ship empty metal frames out the door; every C2RPS-CHAS2 chassis undergoes strict mechanical and electrical validation:
- Inbound Mechanical Inspection: Inspection of the 19″ rack ears, internal module guide rails, backplane connectors, and thumbscrews for physical alignment and corrosion.
- Backplane Continuity & Voltage Testing: Checking DC distribution traces, ground planes, and power pass-through pins to ensure zero short circuits or open paths.
- Module Ingestion & Latching Test: Inserting live C2RPS power supply modules into both Bay 1 and Bay 2 to confirm mechanical alignment and blind-mate connector handshakes.
- Full-Load DC Power Output Verification: Running connected load tests through rear output ports to verify voltage stability under maximum current draw.
- Anti-Static & Protective Packaging: Cleaning connector contacts with isopropyl cleaner and wrapping the chassis in heavy anti-static bubble packaging prior to dispatch.
The Veteran’s Tech Trap Guide (Crucial Value-Add)
⚠️ Do Not Mix Power Supply Models! Make sure both power supply modules populated inside the C2RPS-CHAS2 share the exact same wattage and output voltage ratings. Mixing mismatched power cards can cause uneven current sharing or trigger backplane fault locks.
❗ Check Your Output DC Cables: The heavy gauge DC cables connecting the C2RPS-CHAS2 chassis to your target switches use keyed connectors. One thing to watch out for is forcing a connector into a misaligned port—you can bend the high-current pins inside the connector housing.
⚠️ Maintain Rack Airflow Spacing: Even though the CHAS2 chassis is passive, the power modules installed inside generate considerable heat under load. Ensure at least 1U of clearance or proper forced-air cabinet cooling to prevent thermal shutdown on full loads.
Frequently Asked Questions (FAQ for Conversion)
Q: Does the C2RPS-CHAS2 come pre-populated with power supply modules?
A: Typically, the C2RPS-CHAS2 is sold as an empty 2-slot chassis frame unless specified as a bundle. You can populate it with your existing C2RPS power modules or source them separately.
Q: Can I insert or remove a power supply module from the C2RPS-CHAS2 while it is operating?
A: Yes, provided at least one active power supply module is healthy and supplying the connected load, the second module slot is hot-swappable.
Q: Is the Enterasys C2RPS-CHAS2 compatible with modern Extreme Networks switches?
A: It is directly compatible with legacy Enterasys platforms (like SecureStack) and select legacy Extreme Networks equipment designed to accept external C2RPS DC inputs. Verify your switch’s rear RPS port specifications before deployment.
Q: What should I do if the power LED on the connected switch does not indicate external RPS power?
A: Check that the rear DC inter-connect cable is fully seated and screw-locked at both ends. Also verify that the installed C2RPS module in the chassis is receiving active AC input power.
Q: What warranty is offered on this surplus Enterasys chassis?
A: Every C2RPS-CHAS2 chassis includes a standard 12-month functional warranty. If you experience any backplane or structural issues within one year, we offer a direct replacement or a full refund.
