FAQs

Q: What is the difference between the 32C and 32S models?
A: The 7050CX3-32C ships with 16GB RAM and 32GB flash as standard, while the 32S includes 8GB RAM and 8GB flash. The 32C model also requires EOS 4.30.4 or later, compared to 4.20.5 for the 32S.

Q: Can this switch operate with AC power?
A: No, the DC-F variant is equipped exclusively with -48VDC power supplies designed for telecom central offices and carrier facilities with native DC power distribution. For AC power, consider the DCS-7050CX3-32C-F model.

Q: What deployment scenarios is this switch best suited for?
A: This switch is ideal for telecom central office spine switching, carrier PoP core fabrics, colocation data centers with DC power infrastructure, and cloud or hyperscale spine layers requiring high port density and low latency.

Q: Does this switch support network virtualization?
A: Yes, it fully supports VXLAN and EVPN for Layer 2 overlay networks, enabling seamless multi-tenant environments and workload mobility across distributed data center sites.

Q: What optics and cables are compatible?
A: The QSFP28 ports support a wide range of transceivers including 100GBASE-SR4, LR4, PSM4, CWDM4, DR, and direct attach copper cables (DAC) from 1m to 5m. Breakout cables for 25G and 10G are also supported.
