FAQs

Q: What is the airflow direction of the FAN-7011H-R?
A: The FAN-7011H-R provides rear-to-front airflow, meaning air flows from the fan side (rear) to the switch port side (front). This is also referred to as back-to-front airflow and is compatible with -R designated power supplies and systems.

Q: Which Arista switches are compatible with this fan module?
A: The FAN-7011H-R is designed for Arista 7280R3 Series switches, including models such as the DCS-7280CR3-32P4-R, DCS-7280CR3K-32D4-R, DCS-7280PR3-24-R, and other 1RU 7280R3 variants with rear-to-front airflow configurations.

Q: Can I replace this fan module without powering down my switch?
A: Yes, the FAN-7011H-R is a hot-swappable field-replaceable unit. You can replace it while the switch remains operational, minimizing downtime. The 7280R3 Series supports N+1 fan redundancy, allowing one fan to fail or be removed without impacting system cooling.

Q: How many fan modules does a 7280R3 switch require?
A: Most 7280R3 Series switches use 3 or 4 fan modules depending on the model. For example, the DCS-7280CR3-32P4-R uses 3x FAN-7011H-R modules, while the DCS-7280PR3-24 models use 4x FAN-7011H-F or FAN-7011H-R modules depending on airflow direction.

Q: What is the difference between FAN-7011H-R and FAN-7011H-F?
A: The FAN-7011H-R provides rear-to-front airflow (back-to-front), while the FAN-7011H-F provides front-to-rear airflow (forward airflow). You must match the fan airflow direction with your power supply and chassis airflow configuration for proper thermal management.
