N3K-C3408-S Overview
An eight-slot chassis whose connectivity depends on installed modules
Cisco N3K-C3408-S is the Nexus 3408-S eight-slot chassis in a 4RU form factor. The platform accepts 100G or 400G Line-Card Expansion Modules. Its headline port capacity describes a populated configuration, not a guarantee that modules are included with a bare chassis quotation.
Choose between the documented module configurations
Cisco identifies NXM-X16C as the 100G expansion module and NXM-X4D as the 400G module. The platform supports configurations offering 128 ports of 100G or 32 ports of 400G. Do not add both headline counts together or describe both as simultaneously included; specify the installed module types and quantities on the actual bill of materials.
Separate the base chassis from spares and supporting components
The lifecycle table names the bare N3K-C3408-S as an eight-slot chassis and lists N3K-C3408-S= separately as a spare. Verify fans, power supplies, blank modules and software entitlements as explicit quotation items. Also establish the rack, power and cooling requirements for the intended populated configuration before installation.
Record the lifecycle and migration context for this modular system
The exact notice ended sale on April 25, 2023 and gives April 30, 2028 as the last applicable support date, subject to entitlement. Its migration information points to the Nexus 9408 platform. Compare chassis, line-card, software and optical requirements independently; that reference does not establish interchangeable modules or a drop-in replacement.
