❓ Frequently Asked Questions (FAQs)
Q1: What airflow does the MQM9700-NS2R support?
A: The MQM9700-NS2R features Connector-to-Power (C2P) airflow, which directs air from the connector side to the power supply side — perfect for environments with reverse airflow setups.
Q2: How many total NDR connections are supported?
A: The switch supports up to 64 NDR (400Gb/s) connections using 32 OSFP ports and breakout cables (2x NDR per port).
Q3: Is this model suitable for AI and HPC workloads?
A: Yes, it’s specifically built for AI training clusters, scientific computing, and cloud-native high-performance environments.
Q4: Can I hot-swap components like fans and power supplies?
A: Yes. Both fans and power supplies are hot-swappable, allowing for non-disruptive servicing.
Q5: What’s the difference between MQM9700-NS2R and MQM9700-NS2F?
A: The main difference is airflow direction. The NS2R model uses C2P (reverse airflow), while the NS2F model uses P2C (forward airflow).
