FAQs

Q: Can I replace the FAN-7800-HS while the switch is running?
A: Yes, the FAN-7800-HS is hot-swappable and can be replaced without powering down the chassis. The N+1 redundant cooling system maintains proper temperatures during fan module replacement.

Q: Which Arista 7800 Series switches is this fan module compatible with?
A: The FAN-7800-HS is compatible with all Arista 7800 Series modular switches including the 7804, 7808, 7812, and 7816 chassis platforms, supporting both R3 and R4 fabric modules.

Q: How do I know if a fan module needs replacement?
A: The system monitors fan health continuously. Failed fans trigger console error messages and illuminate attention LEDs on the affected fabric module, allowing quick identification for replacement.

Q: What tools are required to replace this fan module?
A: No special tools are required. The FAN-7800-HS uses a tool-less lever mechanism for removal and installation. An ESD wrist strap is recommended during the replacement procedure.

Q: Does replacing a fan module affect switch performance?
A: No, the redundant cooling architecture ensures that replacing a single fan module does not impact system performance or airflow. The remaining fans automatically adjust speed to maintain proper cooling.
