A 42U server rack synoptic diagram organizing Cisco switches, FortiGate firewall, MikroTik router, patch panels, and PDU units in a structured network stack. Traffic flows from patch panels through layered switching (Catalyst 2960 and 9300 series) to security and routing appliances, with power distribution managed by dual PDU units. This layout demonstrates enterprise network segmentation and redundancy best practices for medium-scale data centers.
