Specifications
Confirm model, interface type, rate, power, airflow and software version before ordering.
Selection answer
The retained source identifies the H3C S5120V2-LI family as managed Layer 2 Gigabit access. It does not support the previous page title's Layer 3 claim and contains no model-level table. This page therefore focuses on compatibility and replacement: establish the required switching, routing, uplink and management functions before retaining this model on a shortlist.
Compatibility dimensions
| Dimension | Question to resolve |
|---|---|
| Access | Do endpoint speed, port count, VLAN and aggregation requirements fit? |
| Uplink | Are media, speed, optics or cables and the peer device compatible? |
| Network functions | Does the target release support the required Layer 2, Layer 3, multicast, security and QoS functions? |
| Operations | Can Comware configuration, monitoring, logging, backup and upgrades enter the current workflow? |
| Site | Do power, cooling, dimensions and acoustics fit the installation? |
Suitable and unsuitable situations
- Consider it: existing Comware operations and primarily Layer 2 Gigabit access requirements.
- Run a PoC: environments dependent on specific authentication, multicast, stacking, management or third-party optics.
- Do not carry it forward automatically: projects whose functions exceed the verified platform or whose lifecycle cannot be confirmed.
How to judge a replacement
Compare interfaces and uplinks, performance, protocols, configuration migration, power, dimensions, software support and lifecycle. A faster new model may still behave differently in command syntax, optics handling or failure recovery, so substitution requires documented testing.
Test path
- Export current VLAN, aggregation, authentication, ACL, QoS and management requirements.
- Obtain function and compatibility evidence for the candidate code and software.
- Rebuild or import the configuration in an isolated environment and record differences.
- Test access, uplinks, authentication, monitoring, recovery and rollback.
- Use the test record to define permitted and prohibited replacements.
Frequently asked questions
Does this model definitely provide Layer 3 routing?
The old record does not provide model-level evidence. Check the complete ordering code and the target software function table.
Does a shared Comware name remove the need for testing?
No. Platforms and releases can differ in commands, defaults, licenses and supported functions.
Evidence boundary: No specific software function, performance figure, lifecycle or replacement relationship is confirmed here. Use model documents and test records.
