Specifications
Confirm model, interface type, rate, power, airflow and software version before ordering.
Decision answer
The H3C S5120V2-28P-HPWR-LI may be considered for managed Gigabit campus access, but the source retained for this record confirms only the S5120V2-LI family position. It does not contain a model-level port or power table. The HPWR suffix must therefore be verified against the complete ordering code before PoE capability, power configuration or uplink layout is accepted.
Specification evidence to request
| Decision area | Required model-level evidence |
|---|---|
| Access ports | Quantity, media, speeds and combinations that can operate together |
| PoE | Supported standard, per-port boundary, total budget and budget after a power fault |
| Uplinks | Port type, speed, supported optics or cables and peer compatibility |
| Power and cooling | Power modules, redundancy behavior, airflow, consumption and site constraints |
| Software | Comware release, required Layer 2 functions, management and license boundaries |
Suitable and unsuitable situations
- Consider it: campus or branch access for APs, cameras or other powered Gigabit endpoints after the load is documented.
- Test first: deployments that depend on a controller, authentication system, management platform or specific transceiver.
- Do not select yet: projects without a PoE load sheet, uplink plan or current lifecycle confirmation.
How to compare related variants
Do not treat 28P-HPWR-LI, 28P-PWR-LI and 28P-LI as identical configurations. Compare the complete ordering codes, powered-port capability, total PoE budget, power modules, uplinks, dimensions, acoustics, software and support period. A suffix difference can change the bill of materials.
Procurement and test path
- List endpoint types, quantities, maximum demand and ports that must remain powered.
- Obtain the matching data sheet, front-panel diagram and power table for the complete code.
- Check uplink media, peer devices, software and protocols against the existing network.
- Use representative endpoints to test PoE negotiation, sustained load, uplink failover and configuration recovery.
- Record labels, software, modules and results in the acceptance file.
Frequently asked questions
Does HPWR always prove a higher PoE budget?
No. A suffix is not sufficient contractual evidence. Confirm the exact power and PoE configuration in the model document and accepted bill of materials.
Can this page replace a quotation configuration?
No. A quotation should identify the complete ordering code, quantity, included modules, software and support scope.
Evidence boundary: This page does not confirm price, stock, lead time, authorization, warranty or current lifecycle. Use dated project documents for those claims.
Browse the H3C switch catalog and use the campus-switch buyer guide to prepare the PoE and uplink checks.
