C9400-SSD-960GB Description

C9400-SSD-960GB is a Cisco Catalyst 9400 Series 960GB M2 SATA SSD module for supervisor-local storage on Catalyst 9400 modular switch deployments.

This SKU is a storage module, not a chassis, supervisor engine, line card, power supply, fan tray, optical module, or software license. It is used when the Catalyst 9400 build needs the largest Cisco-listed M2 SATA capacity in the 240GB, 480GB, and 960GB storage group.

Before quoting C9400-SSD-960GB, confirm the target supervisor, the installed Cisco IOS XE release, the application-hosting storage requirement, and whether the maintenance plan allows the system to be powered down for SSD installation or replacement.

Cisco Catalyst 9400 Series 240GB M2 SATA memory (Supervisor)

  • C9400-SSD-960GB is the highest-capacity Catalyst 9400 M2 SATA supervisor storage option listed in this 240GB, 480GB, and 960GB group.
  • The comparison is a storage-capacity decision; these SSD SKUs do not add Ethernet ports, PoE output, chassis slots, uplink bandwidth, or software entitlement.
  • For replacement projects, confirm whether the existing supervisor uses 240GB, 480GB, or 960GB storage before approving a like-for-like or capacity-upgrade quote.
  • For new builds, align the SSD capacity with the application-hosting plan and the customer’s operational file-retention requirements.

Selection Guide

1. Choose this SKU for the 960GB Catalyst 9400 SSD option

Select C9400-SSD-960GB when the design specifically requires the Cisco-listed 960GB M2 SATA supervisor storage module.

2. Keep the order tied to supervisor storage

This SKU belongs to the Catalyst 9400 supervisor storage path. It should not be substituted for a supervisor engine, line card, fan tray, power supply, network module, or license.

3. Confirm software and file-system handling

Cisco documentation lists M2 SATA support from Cisco IOS XE Everest 16.6.1, with EXT4 as the default file-system format and EXT2, EXT3, and EXT4 support. Confirm the running software and any disk0: files before formatting or replacing the module.

4. Plan the maintenance window before replacement

Cisco states that the M2 SATA SSD module does not support hot-swapping, so installation or replacement should be planned for a powered-down maintenance window.

    Highly recommend Layer23 for anyone in B2B procurement. Wish the lead time was a bit shorter, but product quality made up for it.
