Maintain rack discipline and service access for Cisco Firepower 2000 appliances with this slide rail kit spare. Built for the Firepower 2000 family, it helps secure the chassis in standard rack deployments while preserving the ability to slide the unit out for maintenance and replacement tasks. That matters when security appliances sit in production paths and downtime windows are tight. As a spare part, this kit is suited to teams that keep critical hardware on hand for field replacement or lifecycle support. It is especially relevant for environments where the original rail set is missing, damaged, or reserved for a secondary install. The rail design supports a cleaner rack presentation than improvised mounting, and it helps reduce handling risk when servicing the appliance. Cisco identified this item as end-of-sale hardware, with the last date to order through Cisco point-of-sale mechanisms on May 27, 2025. For organizations extending the life of existing Firepower 2000 deployments, the right rail kit can be the difference between a controlled service event and a rack-side workaround.
