CISCO FP8390-K9 Firepower 8000 Series Appliances

FP8390-K9 Hardware Identity

FP8390-K9 is a physical high-capacity classic NGIPS appliance in the Cisco FirePOWER 8000 Series. It is security hardware, not an Ethernet switch and not a software-only entitlement. Cisco documents it as a 2U PG35 chassis designation with 60 Gbps IPS throughput in Cisco's model table.

Exact interface and chassis boundary

up to four network modules in any supported combination. Fully stacked model profile with no further stacking expansion.

Memory: 512 GB RAM. Power: Redundant hot-swappable power supplies. Scale: Represents the fully populated 8300-series scale point.

Sixty-gigabit inspection estate

Treat this as a multi-component security system, not a single generic appliance. Reconcile every chassis, stacking connection, network module and power feed. Benchmark the complete inspected path with realistic packet sizes and policy services, then preserve the topology and failure-domain diagram with the serial inventory.

Fully stacked migration program

Because the 8390 profile is already at the documented 8300-series scale point, capacity growth requires a replacement architecture rather than another stacking kit. Stage policy conversion, traffic migration and rollback by security zone. Record signature availability and management compatibility as lifecycle constraints.

Recovery ownership

Assign owners for traffic bypass, policy restoration, manager recovery and evidence review. Include a timed rehearsal so the recovery plan is operational rather than a document-only control.

Change rollback

Keep a pre-change traffic baseline, cable map and policy checksum. Define rollback criteria that restore inspection safely without reintroducing an unsupported configuration as the permanent state.

Event evidence

Generate representative intrusion, connection and health events and confirm timestamps, retention and forwarding to the approved monitoring system before accepting the appliance.

Lifecycle and procurement decision

Cisco's 7000/8000 lifecycle notice gives June 30, 2024 as the last support date. Before purchase or reuse, reconcile the exact serial inventory, software and management compatibility, security-content availability, policy migration and replacement owner. Do not represent an end-of-support platform as a current Cisco-supported security control.
