C9400-SSD-480GB Description

C9400-SSD-480GB is a Cisco Catalyst 9400 Series 480GB M.2 SATA SSD module for supervisor storage and application-hosting workloads on supported Catalyst 9400 deployments.

This SSD is used when a Catalyst 9400 configuration needs more local supervisor storage than the default 240GB option. It is a storage component, not a switching line card, license, power supply, or optical module, so buyers should verify supervisor selection and software application-hosting requirements before quoting.

Choose this 480GB option when the project needs a mid-capacity SSD for hosted applications, container files, or local storage planning, while keeping the final bill of materials aligned with Cisco Catalyst 9400 supervisor configuration rules.

Application Scenarios

Supervisor storage upgrade in a Catalyst 9400 build

Use C9400-SSD-480GB when the project BOM calls for more local supervisor storage than the standard 240GB storage selection, but does not require the highest listed 960GB SSD option.

Application-hosting storage for IOS XE deployments

For Catalyst 9400 environments that use application hosting, this SSD gives the active supervisor local M.2 SATA storage for hosted applications and related files.

Spares and configuration alignment

When replacing or expanding Catalyst 9400 supervisor storage, match the quoted SSD capacity to the operational requirement, the selected supervisor, and the customer configuration record.

  • C9400-SSD-480GB sits between the 240GB and 960GB Catalyst 9400 SSD options, so it is useful when the deployment needs additional storage but the largest SSD is not required.
  • The comparison should be handled as a storage-capacity decision; these SSD SKUs do not change switching ports, PoE budget, supervisor uplinks, or chassis slot count.
  • For quotes, confirm whether the supervisor is being ordered with its default 240GB storage or with a different SSD size selected in the configuration.

Selection Guide

1. Choose this SKU for mid-capacity supervisor storage

Select C9400-SSD-480GB when the Catalyst 9400 design needs a confirmed 480GB M.2 SATA SSD option for supervisor-local storage.

2. Do not treat it as a network interface module

This SKU is a storage module. It does not add Ethernet ports, uplink ports, PoE capability, or switching bandwidth.

3. Confirm the supervisor and chassis configuration first

Before quoting, check the selected Catalyst 9400 supervisor, whether a secondary supervisor is part of the build, and whether the SSD quantity matches the intended supervisor configuration.

4. Keep application-hosting requirements explicit

If the customer plans to host applications on the switch, confirm storage capacity requirements and active-supervisor behavior with the network engineering team before finalizing the BOM.

What to Confirm

Why It Matters

Exact SKU

C9400-SSD-480GB

Prevents accidental substitution with the 240GB or 960GB SSD option

Supervisor Context

Catalyst 9400 supervisor storage requirement

The SSD is tied to supervisor storage, not line-card expansion

Capacity Requirement

480GB selected instead of default 240GB or larger 960GB

Keeps storage capacity aligned with the application-hosting plan

Application Hosting Plan

Whether local SSD storage is needed for hosted applications

Confirms that the SSD is required for the intended IOS XE use case
