Explanation

A is correct because the FAN board on the OptiXtrans E6616/OptiX OSN 1800 V Pro is specifically designed with fault tolerance in mind - its four fans operate independently, so a single fan failure does not immediately compromise the system. Huawei's design specification confirms the device can sustain normal operation for up to 96 hours with one fan down, provided ambient temperature stays within the -5°C to 40°C range. This grace period gives technicians time to replace the faulty fan before thermal damage or service disruption occurs.

B is incorrect because it contradicts the documented fault-tolerance specification; the system does not shut down or degrade immediately upon a single fan failure.

Memory tip: Think "96 hours = 4 days of safety net" - matching the 4 independent fans. One fan fails, you have 4 days (within the rated temperature range) to fix it before risk escalates.
