Cisco Nexus N9K-C9372PX-E 48-Port Switch

Optical access ports distinguish the PX-E chassis

N9K-C9372PX-E identifies the Cisco Nexus 9372PX-E with 48 fixed 1/10G SFP+ interfaces and six fixed 40G QSFP+ uplinks. It is the optical-access model, not the TX-E copper variant. Preserve the E suffix when comparing an offered unit with an existing switch.

Build the optical bill of materials from the link plan

For each link, specify speed, fiber type, reach and the peer interface, then verify Cisco transceiver compatibility for the intended software release. The presence of SFP+ or QSFP+ cages does not imply installed optics or cables. This base PID is also distinct from the two-switch B18Q bundle listed in the ordering notice.

Validate the supplied fans and power equipment

Cisco lists four fans and support for up to two power supplies on the 9372PX-E hardware. Confirm power type, airflow and mounting equipment on the quotation. Treat supported redundancy as a configuration requirement to verify, rather than evidence that a complete redundant assembly is included.

Assess legacy use against the closed support window

The exact model notice ended sale on October 30, 2018 and reached its final support date on October 31, 2023. For a legacy replacement, document the required software and feature compatibility and compare current migration options independently. The old notice does not guarantee that a suggested replacement remains available or supported today.
