Frequently asked questions

What is the switching capacity and forwarding rate of the MSN2700-CS2FO?

The MSN2700-CS2FO delivers 8Tb/s full-duplex switching capacity with 8.4 billion packets per second (Bpps) forwarding rate. This non-blocking architecture supports simultaneous wire-speed forwarding across all 32 QSFP28 ports without oversubscription, making it ideal for demanding data center spine and aggregation deployments requiring predictable performance.

What operating systems and management platforms does the MSN2700-CS2FO support?

The MSN2700-CS2FO features ONIE (Open Network Install Environment) support, enabling deployment of multiple open-source and vendor network operating systems. It includes x86 CPU management for flexible OS choices and integrates with NVIDIA Mellanox NEO management platform for certified, interoperable network design and accelerated service deployment.

What transceiver types are compatible with the MSN2700-CS2FO?

The switch supports QSFP28 transceivers for 100GbE connectivity, including both short-range (SR4) and long-range (LR4) optical modules. It also supports SFP28 modules via QSA (QSFP to SFP adapter) for flexible mixed-speed deployments. Active optical cables (AOCs) and passive copper cables are supported for cost-effective short-distance interconnects.

How does the MSN2700-CS2FO compare to 40GbE switches in terms of performance?

The MSN2700-CS2FO provides 2.5x higher per-port bandwidth (100GbE vs 40GbE) while maintaining lower latency and power consumption than equivalent 40GbE solutions. The Spectrum ASIC delivers superior packet processing efficiency, enabling organizations to consolidate multiple 40GbE switches into fewer 100GbE units, reducing operational complexity and TCO.

What power consumption and cooling requirements does the MSN2700-CS2FO have?

The MSN2700-CS2FO operates at approximately 150W typical power consumption, among the lowest in the 100GbE switch market. It features dual AC power supplies (50-60Hz, single phase) with P2C (port-to-CPU) airflow design, enabling efficient integration into standard data center cooling infrastructure without requiring specialized power or thermal upgrades.

Is the MSN2700-CS2FO suitable for open networking deployments?

Yes, the MSN2700-CS2FO is purpose-built for open networking with ONIE support, x86 CPU architecture, and compatibility with open-source NOS platforms. It enables vendor-neutral deployments, reducing lock-in and supporting heterogeneous network environments where organizations mix hardware from multiple vendors with unified management.

What are the physical dimensions and rack mounting requirements?

The MSN2700-CS2FO is a 1U form factor switch measuring 1.7 inches (H) x 16.8 inches (W) x 27 inches (D), weighing approximately 24.47 lbs. It is both rail-mountable and rack-mountable with standard-depth design. A rail kit is included for convenient 19-inch rack installation in standard data center environments.
