FAQ

Q1: Can the RH102AN operate without redundant power supplies?
A1: Yes, it operates on a single power supply, but redundancy is recommended for uninterrupted operation.

Q2: Which SFP modules are compatible with the RH102AN?
A2: Compatibility depends on distance and fiber type (single-mode or multi-mode). Consult Foxboro documentation.

Q3: Can it integrate with non-Foxboro devices?
A3: Yes, as a standard managed Ethernet switch, it supports typical VLAN and network protocols.

Q4: What maintenance is required for long-term operation?
A4: Periodic fan inspection, firmware updates, and monitoring of redundant power supplies ensure optimal performance.
