N3K-C3132Q-40GX - Cisco Nexus 3000 Series 32 QSFP+ ports, 1RU switch

Identify the 3132Q-X before comparing the connector count

Cisco N3K-C3132Q-40GX is the Nexus 3132Q-X, a one-rack-unit switch with thirty-two QSFP+ ports. The 40GX order identifies the X hardware revision, distinct from the earlier 40GE and the separate memory-enhanced XL model. Preserve that suffix when matching a replacement to an installed system.

Four SFP+ connectors share the first QSFP+ interface

The hardware guide explicitly describes four SFP+ ports internally multiplexed with the first QSFP+ port. They are an alternative connection arrangement, not four extra independent interfaces on top of all thirty-two QSFP+ links. QSFP+ supports native 40G or four-lane 10G operation; verify the intended port map, software restrictions and supported cabling before calculating usable connections.

This model has passed its final Cisco support date

The exact lifecycle notice ended sale on April 27, 2020 and lists April 30, 2025 as the last date of support. That milestone has passed. An available hardware quotation must not be interpreted as renewed Cisco support or continued software maintenance; document the maintenance and replacement plan separately.

Assess the named migration platform independently

Cisco identifies N3K-C3132C-Z in the migration row for this exact PID. Before selecting it, compare required interface modes, installed optical modules, configuration and software entitlements. For an existing 3132Q-X unit, also confirm fan and power-supply airflow and the accessories actually included in the offer. Do not infer a complete rack-ready configuration from the chassis model alone.
