The RM-CI-T4 gives you the ability to mount your Cisco Meraki MX64 and MX67-Series in a 19" rack. The rack is tailored specifically for the listed models to guarantee a perfect fit. The firewall is placed backwards in the rack, to ensure the connection are easily accessible. A fiber optic cable is used to redirect the status light from the back of the rack mount kit to the front of the server cabinet.
