Huawei S3700-28TP-SI-AC Campus Access Switch

S3700-28TP-SI-AC Exact Model Scope

S3700-28TP-SI-AC is an exact Huawei S3700-SI campus-switch identity with AC power. Huawei's model-level InfoFinder entry associates it with V100R006C05, preventing confusion with EI, DC-powered, PoE or later S-series variants.

Use the 28TP identity in the port plan

Prepare a numbered endpoint and uplink schedule before replacement. Confirm the physical role of every front-panel interface on the delivered switch, identify which links require optical media, and leave documented capacity for management or recovery rather than copying a plan from a different S3700 suffix.

Control software and stack compatibility

Huawei lists S3700-SI service-port stacking on specific V100R005 and V100R006 releases. A proposed stack expansion therefore needs a release comparison, configuration backup and approved interconnect plan before any cable is inserted; mixed software should be corrected under a maintenance window.

Migration checks

Export the existing VLAN, loop-protection, authentication and management settings, then map only the required functions to the target release. Verify AC input, rack hardware and every optical module independently because those procurement items are not established merely by the base switch model.

Acceptance

Inspect the complete S3700-28TP-SI-AC label, record serial and running version, test assigned access and uplink paths, confirm management isolation and validate stack behavior only when stacking is part of the approved design.
