Load with one module unavailable
Determine the load that must remain supported during maintenance or a module failure. Do not treat the sum of installed module ratings as the guaranteed redundant output.

Build the quotation around the complete configuration
Redundancy is a system property. The remaining power modules and distribution components must support the required load if a module becomes unavailable. Hot-swap capability and redundant operation should be checked separately against the supported system design.
Matched modules and cage
Confirm the exact module model, revision, quantity, cage or backplane, cable harness and monitoring requirements. Mixed modules should not be assumed to work together.
Service and monitoring
Check supported hot-swap procedures, indicators, alarms and system-controller behavior. Installation and servicing should follow the approved equipment documentation.
Compare the supply configuration
| Option | What it describes | What to confirm |
|---|---|---|
| Power module only | One removable PSU | Confirm whether any cage or cable is included |
| Cage / backplane only | The specified distribution assembly | Confirm compatible modules and output harness |
| Complete redundant assembly | The agreed cage, modules and accessories | Request an itemized configuration list |
Information to include in your inquiry
Model & system
Full model and suffix, chassis or equipment model, required output and input supply, dimensions and connector information.
Order & delivery
Quantity, destination, delivery requirement and whether you need modules, a cage, cables or a complete assembly. Ask for the applicable warranty and supply terms.
Frequently asked questions
Are two installed PSUs automatically redundant?
No. The system load, power distribution, module combination and supported operating mode must provide the required behavior.
Is hot-swap the same as redundancy?
No. Hot-swap concerns supported replacement during operation; redundancy concerns continued system operation when a component is unavailable.
Can the two module wattages be added together?
That depends on the supported operating mode. For redundant operation, check the remaining supported capacity when one module is unavailable.
Why are some system models not listed yet?
Configurations that still need model or component verification are withheld from the public product list. Send your requirement for an individual check.
