With 2 100 Gigabit QSFP28 ports and 16 25 Gigabit SFP28 ports, the CRS518-16XS-2XQ is the perfect cost-effective addition to any enterprise network or data center. And with dual-redundant power supplies and hot-swappable fans, you don't have to worry about unnecessary downtime. The 25 Gigabit ports are backwards compatible with 10 Gigabit and 1 Gigabit SFP devices. Two hot-swap power supplies support a high input voltage range: 100-240V. The board itself consumes up to 45W of power, while the total maximum power consumption increases to 77W with all the extras.
