FAQs

Q: Does the N3K-C3524P-10GX support Power over Ethernet (PoE)?
A: No, the N3K-C3524P-10GX is a pure 10 GbE fiber/copper switch optimized for high-density 10 Gbps connectivity and does not support PoE. It is designed for data center server and storage connectivity.

Q: Can I expand the switch from 24 to 48 ports?
A: Yes, the N3K-C3524P-10GX has 48 physical SFP+ ports on the hardware, with 24 ports enabled by default. You can upgrade to enable all 48 ports through a Cisco port expansion license.

Q: What makes this switch suitable for high-frequency trading and HPC environments?
A: The N3K-C3524P-10GX features Cisco Algo Boost technology delivering ultra-low latency of less than 200 nanoseconds, precision timing with IEEE 1588 PTP support, and a 1-PPS timing port. These capabilities are critical for time-sensitive applications in financial trading and HPC clusters.

Q: Does this switch support 40G connectivity?
A: Yes, the Nexus 3500 platform can achieve 40 Gigabit Ethernet by combining four sequential SFP+ interfaces into a logical 40G port using breakout functionality and appropriate cabling. This requires configuration via NX-OS commands.

Q: What routing protocols are supported on the N3K-C3524P-10GX?
A: The switch supports industry-standard Layer 3 routing protocols including OSPF, BGP, EIGRP, RIP, VRF-Lite, VRRP, and PIM. It also supports VXLAN routing, Virtual Device Context (VDC), and vPC for advanced data center deployments.
