Hello all,
I got a Switch: 3750-24PS, it is making noise. It sounds like fan issues.
captured "show env all" and "show log", no errors found.
checked Cisco 3750 data sheet:
Cisco Catalyst 3750-24PS: 38-42 dB45dB.
Anybody know the acceptable dB range? And how could I measure the dB?
Does cisco have specific procedure for noises issue?
Your reply and post is appreciated.

Anybody has better idea? If the switch needs to be sent to RMA, any testing procedure that I need to apply?
I appreciate your reply.

nope, just call the TAC for an RMA and say the fans are roaring and need to be replaced before they fail and your network goes down.

A noisy fan is normally a fan that will die soon.
You need to contact whoever supports your network - be it Cisco or a Partner to arrange replacement.

A 3750 fan shouldn't be failing already they aren't that old , not saying it can't . I believe the fans are variable speeds and they can be noisy if they ramp up if the closet temp is high , then this is normal .

Thank you guys for your reply.
I did check the switch temp. via "sh env. temp."
it showed " temperature: OK"
I also doubt the closet temperature is a factor that causes fan issue.
Is it possible in this situation?
I just want to confirm it before the switch sent for warranty.
