Why reject 96×SFP28 copy for N9K-C93600CD-GX?

That faceplate belongs to a different Nexus class. QianliSwitch maps N9K-C93600CD-GX to Cisco OEM 28×QSFP28 + 8×QSFP-DD specifications only.

Is Ruijie PoF the same as RJ45 PoE?

No. PoF delivers power over hybrid fiber cable alongside optical data. It is not a copper 802.3at closet design. Confirm hybrid cable plant and PSU modules before RFQ.

What ports does RG-S5750-24SFP4XS24DP-UP provide?

Ruijie materials list 24 × 1G SFP downlinks, 4 × 1G/10G SFP+ uplinks, and a DB78 hybrid power interface for up to 24 Power-over-Fiber outputs (up to 100 W each). See RG-S5750-24SFP4XS24DP-UP.

Is N9K-C93600CD-GX a 25G SFP28 leaf?

No. Per Cisco N9300-GX materials, N9K-C93600CD-GX provides 28 × 40/100G QSFP28 and 8 × 40/100/400G QSFP-DD ports. For a 48 × SFP28 leaf, evaluate N9K-C93180YC-FX3.

What ports does CE5855-48T4XS have?

What ports does CE5855-48T4XS have?CE5855-48T4XS lists 48 × 1G RJ-45, 4 × 10G SFP+, and 2 × 40G QSFP+ with 336 Gbps / 252 Mpps on authorized family data. Quote the exact hardware suffix (-B/-EI/-F) on the RFQ.

Overview

Exact-PID comparison for data-center leaf shortlists. Higher fabric speed does not make GX an automatic drop-in for an FX3 leaf.

Buyer decision summary

Choose FX3 when servers/storage present SFP28 at 25G and six 100G uplinks meet fabric math.
Choose GX when attach is QSFP28 100G and native QSFP-DD 100/400G fabric options are required.
Choose neither for campus PoE/PoF designs, Multi-GE copper closets, or modular 9500 chassis requirements.

Migration note: Moving from FX3 to GX is an optic-class and oversubscription redesign, not a cable swap.

Optics, breakout, and software

GX breakout is port-group dependent. Cisco documentation describes quad grouping on ports 1–24 and odd/even limitations for some 4× breakouts; QSFP-DD ports 29–36 have separate profile/breakout notes, and ACI mode can reserve certain ports as fabric links. Plan optics against the HIG for your software train.

FX3 planning stays in the SFP28 + QSFP28 ecosystem. Do not assume FX3 MACsec/timing features transfer unchanged to GX.

Power, airflow, growth

Confirm dual hot-swap PSU intent and airflow direction (PI/PE) for either PID.
Growth: FX3 grows within 25G attach density; GX grows within 100G/400G QSFP ecosystems.
Neither PID is a campus PoE refresh path.

Product-specific FAQs

Is 93600CD-GX just a faster 93180YC-FX3?

No. Different optic technologies and faceplates. They are not interchangeable by swapping optics alone.

Which PID has higher aggregate bandwidth?

N9K-C93600CD-GX lists 12 Tbps vs 3.6 Tbps on N9K-C93180YC-FX3 in Cisco’s published materials for these models.

Do management ports count in the 28+8 map?

No. Management copper/SFP ports are separate from business QSFP ports.

Can I break out every GX port freely?

No. Follow OEM port-group and odd/even restrictions for your release — do not assume universal free breakout.
