FPR4115-NGFW-K9 Hardware Identity

FPR4115-NGFW-K9 is a physical NGFW appliance in the Cisco Secure Firewall 4100 Series. It is security hardware, not an Ethernet switch and not a software-only entitlement. Cisco documents it as a 1RU appliance with two network-module bays with 33 Gbps NGFW and IPS figure in Cisco's published 4115 summary.

Exact interface and chassis boundary

eight on-chassis SFP+ interfaces plus two network-module bays for supported 1/10/40/100-Gbps options. Network modules and optics are separate line items unless the authorized quote explicitly includes them.

Memory: Confirm installed memory and storage by serial inventory; they are not encoded in this PID. Power: Verify both installed power supplies, input type and cords against the receiving record. Scale: Not a FirePOWER 7000/8000 stacking SKU.

Internet-edge NGFW acceptance

Build the acceptance test around the real security policy, application visibility, encrypted traffic, logging and session mix. Record throughput and latency with those services enabled, then compare the result with the required headroom. The published platform figure is a sizing reference, not a promise for every packet profile.

Network-module custody

List each installed network module, transceiver, cable, power supply and SSD by PID and serial. Preserve the FXOS and firewall image versions, entitlement ownership and a tested configuration backup. A chassis-only quotation is incomplete when the intended edge design depends on optional interfaces.

Management compatibility

Verify the last supported device image and the exact management platform release before purchase; a reachable web interface is not proof that policy deployment and event ingestion remain supported.

Optics and media

List each copper, SFP, SR, LR or higher-speed handoff by position and counterpart. Validate reach, fiber type and supported module identity instead of assuming all ports share the same media.

Receiving inspection

Confirm chassis PID, serial, memory, storage, network modules, power supplies, rails and physical condition. Quarantine substitutions until the complete authorized bill of materials is reconciled.

Lifecycle and procurement decision

Cisco lists January 6, 2026 as the hardware and license end-of-sale date for this 4100 generation. 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.
