Cisco Secure Firewall 3K Series Power Supply Blank Slot Cover

Close an unused power-supply bay on a Cisco Secure Firewall 3K Series security appliance with a dedicated blank slot cover. The cover fits a vacant PSU position rather than adding electrical power, connectivity, or firewall capacity. It is the appropriate hardware component when the appliance is deployed without a second installed power supply and the unused bay needs to be covered. FPR3K-PSU-BLANK= supports installations where the available power-supply position remains intentionally unpopulated. Use it on the Secure Firewall 3K Series platform rather than substituting a generic panel or unrelated chassis cover. Its role is limited and specific: it fills the open power-supply slot on the compatible appliance. This component differs from a power-supply module because it contains no power-delivery function. It also differs from a general rack blanking panel because it is made for the appliance’s power-supply bay, not for unused rack units. Select this cover when the required outcome is an enclosed, unoccupied PSU position on the firewall chassis.
