Product Usage Instructions
-
Mounting: Secure the device onto a standard 35mm DIN rail. Ensure there is sufficient clearance (at least 20mm) around the cooling vents for passive airflow.
-
Power Connection: Connect the power supply to the terminal block. The AFS660-SR supports redundant power inputs; it is recommended to use both to prevent downtime in case of a power failure.
-
Network Setup: Insert SFP modules or RJ45 cables into the designated ports. Use shielded twisted pair (STP) cables in high-interference environments.
-
Configuration: Access the web-based management interface or CLI to configure VLANs, RSTP/MRP redundancy, and security settings.
-
Grounding: Ensure the switch is properly grounded via the ground screw to protect against surges and EMI.
Q&A: Frequently Asked Questions
Q: Does the AFS660-SR support “bumpless” redundancy? A: Yes, it supports High-availability Seamless Redundancy (HSR) and Parallel Redundancy Protocol (PRP) when configured, ensuring no downtime during a single point of failure.
Q: Can this switch operate in sub-zero temperatures? A: Absolutely. It is rated for extreme environments, typically operating between -40°C and +70°C.
Q: What is the benefit of the SFP ports on this model? A: SFP ports allow for flexible fiber optic connections, enabling long-distance data transmission (up to 80km+) while providing total immunity to electrical noise.
Q: How do I reset the device to factory settings? A: There is a recessed reset button on the front panel; hold it for more than 10 seconds while the device is powered on to restore defaults.
