FAQs

Q: Is this switch managed or unmanaged?
A: This is an unmanaged (externally managed) model. It is intended to be managed through the NVIDIA UFM platform rather than an onboard subnet manager.

Q: What airflow direction does this model use?
A: It uses connector-to-power (C2P) reverse airflow, so make sure it matches the hot and cold aisle layout of your rack.

Q: Can the ports run at 200Gb/s?
A: Yes. Using port-split, the 32 OSFP cages can provide up to 128 x 200Gb/s (NDR200) ports instead of 64 x 400Gb/s NDR ports.

Q: What cabling and optics does it support?
A: The OSFP cages support passive and active copper cables, active optical cables and optical modules.

Q: Does it include power supplies and mounting hardware?
A: Yes. It has two hot-swappable AC power supplies in a 1+1 redundant configuration and a rail kit for rack installation.
