N9K-C9504-B3-S Cisco Nexus 9504 Chassis Bundle

A defined Nexus 9504 chassis bundle

N9K-C9504-B3-S is a Cisco Nexus 9504 chassis bundle. The exact manufacturer order lists one supervisor, three power supplies, two system controllers, four FM-S fabric modules and three fan trays. Those quantities define this order more precisely than a general Nexus 9000 switch description. Confirm the supplied bill of materials against the complete B3-S code rather than accepting a bare chassis or another fabric-module bundle as equivalent. The published row does not identify line-card or transceiver quantities; obtain an itemized quotation for those components.

Distinguish B3-S from nearby chassis orders

The neighboring B3-E order has four FM-E fabric modules, while B3-S has four FM-S modules. They are different configurations. The same manufacturer list describes FM-S for 100G support and NX-OS, whereas FM-E is described for ACI and NX-OS. This distinction is a reason to review the intended operating mode and line-card combination before substituting modules. A family-level ACI capability statement does not establish that this B3-S configuration is an ACI bundle. The B1 and B2 rows also specify different fabric quantities; compare actual components rather than treating every 9504 bundle as interchangeable.

Review fabric and line-card compatibility

The official 9504 installation guide lists N9K-C9504-FM-S with four fabric modules required for maximum bandwidth and N9K-X9432C-S in that compatibility row. This is a documented platform relationship, not a statement that this line card is included in the B3-S order. Check the exact card, software release, optics and supported port configuration for the deployment. The guide requires all fabric modules in a modular chassis to be the same type. For a four-module configuration, it identifies slots FM 2, FM 3, FM 4 and FM 6. Preserve the installation requirements when inspecting or expanding an offered chassis.

Separate installed quantities from chassis limits

Cisco describes the underlying N9K-C9504 as a four-line-card-slot, 7 RU chassis. Its published limits include two supervisors, two system controllers, four power supplies, six fabric modules and three fan trays. These are chassis capacities, not the B3-S supplied quantities. In particular, this bundle row lists one supervisor; do not interpret the two-supervisor chassis limit as a redundant supervisor pair already included in the quotation. A requirement for supervisor redundancy needs a separately verified second supervisor and supported configuration.

Plan rack space and the actual power configuration

The manufacturer chassis dimensions are 12.25 by 17.50 by 33.15 inches, with a listed chassis weight of 84 lb. Treat these as chassis planning figures, not shipping dimensions or the weight of a fully populated offered bundle. Check rack depth, rails, access and installation handling. The exact B3-S row gives three power supplies without establishing their individual part numbers or input choices. Ask for the power-supply models, input voltage, cords and intended redundancy mode on the actual bill of materials; three supplies alone do not establish a sufficient power budget for any arbitrary line-card load.

Prepare a configuration-specific quotation

Provide N9K-C9504-B3-S, the required line cards and optics, NX-OS release, rack and power constraints, quantity and destination. Have the supplier confirm every listed module, the offered condition, accessories, software and support entitlements, availability and dispatch arrangements. A historical manufacturer price list is used here only to identify the order and components; its price columns are not the selling price on this page. The official image shows a Nexus 9504 chassis with example modules. It is a chassis reference, not a photograph or bill-of-materials confirmation for the offered B3-S unit.

N9K-C9504-B3-S purchase questions

Does the order include two supervisors? The exact B3-S row lists one, even though the chassis supports two. Does four FM-S mean six fabric modules? No; the published bundle quantity is four. Are line cards and optics established by this order description? Their quantities are not specified in the cited B3-S row, so confirm them separately. Can B3-E be substituted automatically? Its FM-E configuration differs and needs its own operating-mode and compatibility review.
