Huawei S2700-9TP-EI-DC Compact DC Access Switch

S2700-9TP-EI-DC Standalone DC Variant

S2700-9TP-EI-DC is the DC-input member of Huawei's compact S2700-EI access range. The full suffix matters: it distinguishes this unit from AC and PWR variants and determines the site-power checks required before installation.

Design it as a standalone switch

Huawei explicitly lists S2700-9TP-EI-DC among the S2700-EI models that do not support stacking. Do not buy stack cables or depend on a virtual chassis design for this SKU; document an independent uplink and management path instead.

Verify the DC plant

Before ordering, obtain the exact shipped hardware record and confirm rated input range, connector, polarity, grounding, protection and the site's available feed. The DC suffix alone does not prove compatibility with a particular telecom or cabinet power system.

Protect the exact identity

Keep the complete 9TP-EI-DC string on quotes, receiving labels and spares records. An S2700-9TP-EI-AC or S2700-9TP-PWR-EI has a different power or PoE boundary and must not be substituted without a new electrical and endpoint review.

Acceptance

Record the model label, serial, hardware and software versions, inspect the DC terminal and accessories, verify polarity before energizing, and test every required copper or optical link against the approved site plan.
