Huawei S2700-26TP-EI-AC Enhanced Fixed Fast Ethernet Campus Switch

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

Huawei S2700-26TP-EI-AC belongs to the S2700-EI subseries. Huawei's exact-model mapping associates it with the V100R006C05 documentation branch. The EI designation differentiates its supported software feature set from the SI model, but it does not make every EI-family capability available on this chassis.

This EI model still does not stack

Huawei names S2700-26TP-EI-AC specifically among the S2700-EI models that do not support stacking. Existing text claiming that EI automatically provides stacking is wrong. Plan this unit as a standalone fixed switch and verify network-level redundancy separately.

Non-PoE AC hardware boundary

The AC suffix identifies the power variant, while the absence of PWR means the page must not claim PoE output. Confirm AC input, regional cord, rack accessories and grounding. Do not transfer the 740 W PoE budget or other specifications from S2700-26TP-PWR-EI to this model.

Software and configuration migration

Before replacing an installed unit, record the VRP release, patch, configuration and enabled EI features. Validate that the target software supports the required VLAN, security, routing and management behavior. Configuration syntax or feature availability from a newer S-series platform may not transfer directly.

Procurement acceptance

Match the chassis label to S2700-26TP-EI-AC, inspect ports and power, verify separately ordered optics and test the intended uplinks. Check Huawei lifecycle information and support entitlement before committing a legacy unit to a long-lived deployment, and document a successor path for future replacement.
