FG-4801F FortiGate 4800F Series 4RU AC Hyperscale Firewall

FG-4801F Exact Variant

FG-4801F is a FortiGate 4800F Series high-end firewall. Fortinet documents 8x 400/200/100/40GE QSFP-DD, 12x 200/100/40GE QSFP56, 12x 50/25/10/1GE SFP56 including HA/AUX, and 2 management RJ45. The exact suffix controls storage, power and facility acceptance: this page represents two 1.92 TB drives, AC power.

local storage and AC resilience

Inventory both 1.92 TB drives, verify FortiOS health, retention limits and external export, then test a storage alarm. Separately map the four AC supplies to independent circuits and document recovery after an approved single-feed interruption.

High-speed port acceptance

Record every optic or breakout cable, lane mode, peer, zone and redundancy role. Apply split-port changes before cluster formation where possible because Fortinet documents a restart or grouped-speed effect. Verify management and HA paths independently from accelerated data traffic.

Procurement boundary

Require the exact FG-4801F, power components, rails, optics, software, licenses and support on the quote. Do not add a NEBS claim without an exact NEBS SKU and supporting Fortinet document. Published performance remains dependent on Fortinet test conditions and the deployed policy mix.
