Netgear GS748Tv4 Fan Failure - Replace fan or Switch?
Dear all
A few days ago I noticed a loud rattling noise coming from our GS748Tv4H1 48 port switch. Logging into the web interface I see that there is a 'fan failure'.
I imagine years of dust have got caught in there and caused some damage or that the fan needs cleaning.
However, the switch was purchased in 2011 and is being a bit flakey. For example although it routes traffic okay it is sometimes not possible to connect via the web interface or even ping the device without resetting it. It has been doing this for a year or so now despite regular firmware updates.
It is also a very crucial piece of kit for our network and I’m wondering if I should purchase a new one and keep this as a spare. I notice that this model is still available. Would you recommend the same model or is there something better?
Lastly does anyone know what size fans it uses or if there is a service manual available for this model?
Many thanks
Mark

Hi Mark,
Welcome to Netgear Community!
If switch work long time, sometimes the temperature will increment for forwarding traffic or other operation. So Fan will rotate speed to reduce the temperature, the FAN will be noise.
Please try to power off the switch and reduce the temperature, then power on the switch and upgrade latest firmware, do factory default.
Look forward your reply, thanks.

Thank you very much for the reply. Apologises, for the late response back. As soon as I can I'll try the firmware update.
Kind regards

Hi,
I've updated the firmware to the latest version and powered down the switch as advised. However, the fan is still making a loud noise. I have managed to clean it using compressed air from the outside and it is now spinning again.
Is there any where I can buy a new fan? Are they easy to replace?
Many thanks
Mark
