Fans For The 8-Port Poe+ And Poe++ Models - NETGEAR M4250-10G2XF-PoE++ Hardware Installation Manual

manually controlling the fans, see the following manuals, which you can download by
visiting netgear.com/support/download:
• Audio-video user manual
• CLI reference manual
If the fans are functioning in Off mode (which you only can set manually and only on
certain models) or in Quiet mode, the switch automatically manages the fans and turns
on the fans or gradually increases the speed of the fans under the following conditions:
• PoE+ and PoE++ models: Either the temperature detected by the temperature
sensor or sensors exceeds its threshold or a PoE budget is exceeded.
• LED tiles model (M4250-12M2XF): Either the temperature detected by the
temperature sensor exceeds its threshold or the switch processes a full traffic load.
• Aggregation model (M4250-16XF): Either the temperature detected by the
temperature sensor exceeds its threshold or the switch processes a full traffic load.
