Specifications
Confirm model, interface type, rate, power, airflow and software version before ordering.
Procurement answer
Do not submit an inquiry for the H3C S5120V2-28P-PWR-LI as only a “28-port PoE switch.” The retained source provides a family-level managed Gigabit access description but no model-level port, power or performance evidence. The contract and acceptance plan should bind the complete ordering code to an agreed configuration.
Configuration checklist
| Item | What the bill of materials should state |
|---|---|
| Device identity | Complete ordering code, hardware revision and regional material |
| Interfaces | Copper, optical and management port types, quantities and speeds |
| PoE and power | Standard, budget, power modules, power cords and fault-state capacity |
| Uplink media | Optics, DAC/AOC, distance, peer model and compatibility evidence |
| Software and support | Release, licenses, upgrade path and support boundary |
Where it may fit
- Office-floor, branch or small-campus access after endpoint and PoE demand has been recorded.
- Managed Layer 2 Gigabit projects with explicit VLAN, authentication and monitoring requirements.
- Refresh projects that can validate one unit before a wider rollout.
When to compare another model
Compare alternatives when the project needs faster access, confirmed routing functions, more uplink bandwidth, a different redundancy design, or a lifecycle that cannot be established for this code. Similar product names are not a substitute for matching interfaces, power, software and operations.
Arrival and commissioning tests
- Match the carton and chassis labels to the ordering code and included material list.
- Record the initial software and save the factory configuration.
- Sample access ports, PoE negotiation, VLANs, authentication and uplinks.
- Observe error counters, temperature, sustained power and restart recovery.
- Retain the final configuration, logs, tested ports and exception record.
Frequently asked questions
Are PWR and HPWR interchangeable?
Not from their names alone. Compare exact power, PoE, cooling, dimensions, software and support for the complete codes.
When is a sample test necessary?
Use one before volume purchase when endpoint, transceiver, authentication or management compatibility cannot be established from confirmed documents.
Evidence boundary: This checklist does not promise stock, delivery, price, warranty, authorization or included accessories. Confirm them in a dated quotation.
