FAQs

Q: Which Arista switches is the FAN-7802-H compatible with?
A: The FAN-7802-H is specifically designed for the Arista 7800 Series modular chassis switches, including the 7804, 7808, 7812, and 7816 models. It is not compatible with fixed configuration switches or other Arista series.

Q: What does front-to-rear airflow mean?
A: Front-to-rear airflow means the fan draws cool air from the switch port side (front) and exhausts hot air out the fan side (rear). This configuration is typically used when the front of the switch faces the cool aisle and the rear faces the hot aisle in a data centre.

Q: Can I replace the fan module without shutting down the switch?
A: Yes, the FAN-7802-H is hot-swappable, allowing you to replace it while the switch remains operational. However, it is recommended to replace failed fan modules promptly to maintain proper cooling and redundancy.

Q: How many fan modules does a 7800 Series chassis require?
A: The number of fan modules varies by chassis model. For example, the 7804 chassis typically ships with six fan modules (6xFM-R3). Check your specific chassis configuration for exact requirements.

Q: What happens if a fan module fails?
A: The 7800 Series supports N+1 fan redundancy. If a single fan module fails, the system will continue to operate normally, and the status LED will indicate the failure. However, you should replace the failed fan module as soon as possible to restore full redundancy.
