The front panel carries 48 SFP ports running 1, 10, or 25 Gigabit plus 6 QSFP28 ports at 40 or 100 Gigabit, with MACsec encryption supported on the six QSFP28 uplinks and 4x25G or 4x10G breakout available. The headline feature is the 8GB dynamic packet buffer, which absorbs the microbursts and incast patterns that shallow-buffer switches drop, and routing scale reaches 256K LPM routes and 750K host entries. Switching capacity is 1.8 Tbps with forwarding up to 1.67 Bpps, driven by a 6-core CPU with 32GB of DRAM and 128GB of bootflash. At 1-RU and 27 pounds it drops into a standard leaf position without special racking.\u003c\/p\u003e\r\n\u003cp\u003eThis unit is the back-to-front airflow (port-side exhaust) configuration with two NXA-PAC-1100W AC power supplies and matching NXA-FAN-65CFM fan modules. Both airflow directions and both power types exist for this model, so match the suffix on your existing supplies before mixing units in one chassis row.
