The -CHAS2 is a passive two-slot chassis. It does not contain a power supply by itself, does not provide battery backup, and does not replace a UPS. It accepts up to two separately purchased -PSM 150 W reserve power modules.
Product Introduction
The Enterasys -CHAS2 is a two-slot, rack-mount chassis for the SecureStack C2 Reserve Power System. It holds up to 150 W power-supply modules, providing reserve power connections for compatible non-PoE SecureStack network switches.
Buyers use the -CHAS2 to restore an installed legacy SecureStack backup-power arrangement without changing switch hardware. The chassis itself is passive, so procurement must confirm the quantit modules, matching DC Power/Monitor cables, AC power cords, rack ears, and the exact supported switch model.

Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to This Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| Reserve power does not operate during switch PSU failure | Mis, failed power module, incorrect cable, unsupported switch, or AC source loss | ❌ Usually external | Confirm th is installed, powered, and connected to the switch using the correct DC Power/Monitor cable | The -CHAS2 is passive; troubleshoot the power module, cable, and switch first |
| Chassis has no LEDs or apparent activity | Expectation error; passive chassis has no independent power function | ❌ Not a chassis fault | Inspect the insta status indications, not the empty chassis | Do not replace -CHAS2 because it has no active indication |
| will not seat in chassis | Incorrect module, damaged guides, bent connector, obstruction, or missing hardware | ✅ Possible | Remove AC power, inspect slot guides and module connector, and compare the module labe | Do not force the module; replace damaged mechanical hardware if needed |
| Switch does not recognize reserve power | Wrong DC cable, cable not fully seated, unsupported switch model, failed PSM, or firmware/configuration issue | ❌ Usually external | Inspect both keyed 15-pin D-sub connections and verify that the attached switch is a supported non-PoE SecureStack model | Use the cor cable; PoE and non-PoE cables are keyed differently |
| PoE devices lose power despite RPS installed | Non-PoE RPS arrangement used for a PoE switch, insufficient PoE reserve power, or wrong -POE equipment | ❌ Usually system selection | Confirm whether the switch is a PoE model and verify the installed RPS component family | Use the dedicated PoE reserve-power components for PoE switch protection |
| One switch has reserve power but another does not | Se absent, cable not installed, PSM fault, or incorrect switch connection | ❌ Usually external | Verify each switch has its own pow and dedicated compatible cable | Install and test a separate power module/cable path for each protected switch |
| System drops during facility AC loss | RPS confused with UPS; no battery-backed AC source | ❌ Design limitation | Check whether AC feed comes from a UPS or generator-backed circuit | Feed the RPS from an appropriately sized UPS if ride-through during utility loss is required |
| Loose chassis or intermittent module contact | Rack fasteners loose, missing rack ears, vibration, or damaged slot hardware | ✅ Possible | Isolate AC power, inspect rack mounting, module retention, and chassis rails | Secure the chassis and replace damaged retaining hardware before restoring power |
❗ Critical clarification: is a passive rack enclosure. It is not a 150 W power supply, not a switch, and not a UPS. The active component is the module installed inside it.
❗ Cable warning: Do not interchange PoE and non-PoE reserve-power cables. The 15-pin D-sub connectors are keyed differently. A cable that seems close is not automatically compatible, and forcing the connection can damage the connector or create an incorrect power-monitor connection.
❗ Procurement warning: Before ordering, count insta modules, verify available chassis slots, confirm the protected switch part numbers, and inspect whether the listing includes rack ears, blanking plates, AC cords, DC Power/Monitor cables, and power modules. Many surplus listings are chassis-only.
If you are stuck, provide technical support with photos of the chassis front and rear, insta labels, cable part numbers, protected switch model labels, and the switch power-event log.
Frequently Asked Questions (FAQ)
What is the Enter?
It is a passive, two-slot rack-mount chassis for the Enterasys SecureStack C2 Reserve Power System. It holds up to reserve power modules. It does not include power conversion or battery backup by itself.
Does include power supplies?
Usually no. chassis power modules are separate items. Confirm the exact bill of materials from the seller. A chassis-only purchase will not provide reserve power until compat modules and cables are installed.
How modules can it hold?
It holds up to modules. is identified as a 150 W power supply for non-PoE SecureStack switch reserve-power applications.
Can I use it as a UPS during a building power outage?
No. The Reserve Power System is not a battery-based UPS. It provides reserve switch power from its installed AC-pow modules. If facility AC fails, both the switch and RPS still require a UPS or generator-backed AC source for continued operation.
Can I use this chassis to back up a PoE SecureStack switch?
Not with a standard non connection. Enterasys identifies separate -POE equipment and a differently keyed DC Power/Monitor cable for PoE switch applications. Confirm the exact switch model and reserve-power design before ordering.
a direct replacement foPS-CHAS8?
No. holds two power modules, while -CHAS8 holds up to eight. They serve the same general reserve-power family but have different capacity, rack space, and protected-switch counts. Choose based on the numbe modules and switches you need to support.
Why is a New Sur less expensive than a current RPS system?
It is legacy network hardware. New Surplus stock often comes from canceled deployments, data-center refresh projects, or warehouse inventory. The chassis contains no active power supply on its own, so condition matters mainly for slot guides, connectors, rack hardware, corrosion, and included accessories. Request actual photos and confirm tha module or cable is assumed to be included.
