Huawei S2700-26TP-SI-AC Fixed Fast Ethernet Campus Switch

S2700-26TP-SI-AC is the SI software-tier model

Huawei S2700-26TP-SI-AC is a fixed S2700-SI campus access switch. Huawei's Info-Finder maps this exact model to the S2700-SI subseries and the V100R006C05 documentation branch. The SI suffix is a software-tier distinction and must not be replaced with EI feature claims.

Standalone deployment boundary

Huawei explicitly states that all S2700-SI switches do not support stacking. Design redundancy at the network level rather than presenting this chassis as a stack member. The existing comparison content that implied stacking or redundant internal power for SI variants must not be retained.

AC and non-PoE ordering checks

The AC suffix identifies the AC-powered order variant. This model is not the PWR PoE variant, so endpoint power must come from separate injectors or a PoE-capable switch where required. Confirm input range, regional cord, mounting kit and grounding from the exact hardware record before dispatch.

Port and optic acceptance

Verify the exact front-panel copper and combo/uplink layout against the chassis label and Huawei hardware documentation. Match any SFP to speed, wavelength, fiber type and distance; an optic listed as compatible with the family is not automatically included with the switch.

Lifecycle-led replacement planning

This is a legacy S2700 generation. Before purchase, use Huawei's model-specific lifecycle tool to confirm the current support state and available software. Capture the installed version and configuration, test every required port and plan a supported successor rather than assuming feature parity with a current S-series model.
