Description

Cisco C9400-SUP-1-B Overview

The C9400-SUP-1-B is a Cisco Catalyst 9400 Series Supervisor Engine-1 bundle used to provide control, management and switching functions in compatible modular Catalyst 9400 chassis. It is intended for enterprise campus core, distribution and high-density access designs requiring modular resiliency and long-term scalability.

Key Specifications

Compatibility Planning

Verify chassis model, line cards, power supplies, fan tray, supervisor quantity and IOS XE release before ordering. Redundant-supervisor deployments should use a validated hardware and software combination. Uplink optics, licence level and network design must also be included in the complete bill of materials.

Licensing and Software

Catalyst 9400 deployments require the appropriate Network Essentials or Network Advantage capabilities and the applicable Cisco DNA subscription. Confirm Smart Account, subscription duration, feature requirements and support coverage. Existing chassis may require software or component upgrades before a new supervisor is installed.

Replacement and Upgrade Guidance

For new designs, compare Supervisor Engine-1, 1XL, 1XL-Y and newer supervisor options according to chassis support, scale, uplink speeds, fabric capacity and lifecycle. A supervisor upgrade should be planned together with line-card compatibility, redundancy, software maintenance windows and configuration backup.
