Enterasys C2RPS-PSM Redundant Power Supply Module

Description

3. Key Technical Specifications

Verify exact power rating and chassis compatibility with the target SecureStack C2 switch before ordering. Transformer/AC cord and DC cable are typically separate items.

4. Product Introduction

The Enterasys C2RPS-PSM is a hot-swappable redundant power supply module designed for SecureStack C2 Ethernet switches. It converts universal AC input (85–264 V) to regulated 12 VDC and delivers up to 150 W continuous power, providing automatic backup if the switch’s internal supply fails.

Network and plant engineers install the C2RPS-PSM in a matching RPS chassis (C2RPS-CHAS2 or C2RPS-CHAS8) to eliminate single points of power failure on critical industrial or enterprise LAN segments. The keyed DC cable interface ensures correct connection only to non-PoE SecureStack C2 switches. Because the product line is discontinued, tested surplus modules remain the practical route for maintaining existing high-availability switch installations.

5. Installation & Configuration Guide

Stage 1: Pre-Installation Preparation (10–15 min)
⚠️ Safety First: Notify network operations. Confirm the target switch can accept external RPS power. De-energize the AC feed to the RPS chassis if already installed.
Tools Required: ESD strap, screwdriver set, multimeter, labels, smartphone for photos of existing cabling and LED status.
Data Backup: Photograph the current RPS chassis population, DC cable routing, and any labeled switch ports. Note which switch(es) the module will support.

Stage 2: Removing the Old Module (5–10 min)

1. If the chassis is powered, observe the Status LED.
2. Disconnect the keyed DC power/monitor cable from the rear of the module.
3. Loosen the captive screws and slide the module straight out of the chassis slot.
4. Inspect the chassis connectors and cooling path for dust or damage.
   ⚠️ Retain the old module until the replacement is online and the switch reports stable external power.

Stage 3: Installing the New Module (10–15 min)

1. Confirm the unit is a genuine C2RPS-PSM (not the PoE variant).
2. Align the module with the chassis guides and slide it fully home. Tighten the captive screws.
3. Connect the keyed DC cable between the module rear connector and the corresponding SecureStack C2 switch RPS port.
4. Connect the AC power cord to the module and to a properly rated outlet or PDU.
   Self-Checklist: [ ] Module fully seated [ ] Keyed cable correct orientation [ ] Captive screws tight [ ] AC cord secure.

Stage 4: Power-On & Testing (10–15 min)
Pre-Power Check: Verify AC voltage at the outlet and no visible damage to the cable.

1. Apply AC power. The front Status LED should illuminate green to indicate normal operation.
2. Confirm the connected SecureStack C2 switch recognizes external/redundant power (check switch LEDs or management interface).
3. If dual modules are installed, verify load sharing or failover by temporarily removing AC from one unit (in a controlled maintenance window).
   ⚠️ Troubleshooting: No LED usually indicates AC input or internal fault. Switch does not detect RPS power – check keyed cable seating and polarity. Over-temperature or fan issues require chassis airflow verification.

6. Frequently Asked Questions (FAQ)

Q: Can the C2RPS-PSM be hot-swapped under load?
A: Yes. The design supports hot-swap. The switch continues running on its internal supply or the remaining RPS module while the unit is exchanged. Always follow site lock-out procedures for the AC side when practical.

Q: Is the C2RPS-PSM still manufactured, and is stock genuine?
A: Enterasys/Extreme Networks has discontinued the SecureStack C2 RPS family. Available units are new original or carefully tested surplus. Serial numbers and condition are verified on intake.

Q: What chassis and switches does it support?
A: It installs in C2RPS-CHAS2 (2-slot) or C2RPS-CHAS8 (8-slot) chassis and supplies non-PoE SecureStack C2 switches such as C2G124-24, C2G124-48, C2H124-48, and C2K122-24. It is not compatible with PoE models (use the corresponding PoE RPS module instead).

Q: Will replacing the module interrupt network traffic?
A: When properly installed as a redundant supply, replacement should not interrupt traffic. The switch falls back to its internal supply or the second RPS module during the swap. Always schedule the work in a maintenance window if the network is critical.

Q: Why is the price lower than historical OEM list prices?
A: This is discontinued surplus inventory. Pricing reflects secondary-market availability of tested original units rather than current production cost.

Q: What testing is performed before shipment?
A: Visual inspection, power-on self-test, Status LED verification, and output voltage/current checks under load where possible. Test reports and photos are available on request.
