ASA5508-K8

ASA5508-K8 Exact Hardware Identity

ASA5508-K8 is a physical Cisco ASA 5508-X with FirePOWER services appliance. Cisco's exact ordering description specifies 8 Gigabit Ethernet data ports, AC power and DES encryption edition. FirePOWER software subscriptions are separate term-based items; this hardware PID does not prove a current IPS, malware or URL-filtering term.

Storage and receiving boundary

Verify installed storage and health by serial-specific receiving inspection. Cisco Field Notice FN70476 lists ASA5508-K8 among affected PIDs. Serial eligibility and prior replacement status are mandatory receiving checks.

Lifecycle status

Cisco records August 31, 2026 as the last support date for ASA 5508-X. The K8 PID is DES-limited and must not be described as a K9 encrypted-edge appliance.

Compact K8 branch containment

ASA5508-K8 is Cisco's exact eight-Gigabit-port ASA 5508-X with FirePOWER services and DES. The absence of FPWR in the PID does not change the official product description, while K8 still limits encryption.

Restrict this compact unit to a dated branch exception. Inventory circuits, zones, NAT, management, inspection alerts and every service that must move because it requires supported encryption or software.

Remote-site replacement worksheet

Record cable labels, provider handoff, local contact, console method, power source and the exact traffic-restoration action for each interface. Verify FN70476 serial eligibility and replacement history before any extended operation. Central staff should test translation, routing, log delivery and an intrusion event while the remote technician verifies physical recovery. The worksheet must state the successor model, maintenance window and event that permanently removes this DES-limited appliance from the site.
