SF-300-48P POE is power cycling

[david.baumgarten]

Hello,

I have a SF-300-48P that is power cycling all POE ports (in use) exactly every 30 minutes. The other older cisco POE switches we were replacing did not have this issue. We have about 40 cisco SPA942 IP phones connected to it. Power consumption is about 175 watts total.

This is my second switch, previously tried a SG500X-48P with the same result.

Any ideas how to stop it from cycling?

Thanks for the help,

David

Hello David, what version firmware is the switch running?  If you remove any amount of phones does the switch stop dropping?

Version: 1.1.2

To add to the info, I just realized, one of the old 24 port switches (still in use) is cycling its ports as well. This switch is plugged into the SF-300 via a standard 10/100 port.

I actually do recall this happening with the first new switch i tried as well. After removing the new switch and placing the other old switch back in place the power cycling stopped. Seems like less of a switch issue and maybe a power issue but I don't see why the 2 old 24 port switches play nice together.

More info: the VOIP phones register offsite at the ISPs location.

Almost forgot, removing phones does not appear to resolve the issue. Removing all phones, of course does (on the specific switch)...but there's nothing plugged into the switch at that point.

David, if you could please do the following

config t

log file debug

log console debug

Additionally, please post a

show run

Also please provide

show run interface fa10  (just a port that has a phone connecting).

show run interface shows "Empty configuration"

[Tom Watts]

Okay, next time the phones reboot provide the following 2 commands

show log

show log file

Additionally, please choose 1 phone port and do the following

config t

int fa10

negotiation 100f

Choose another phone port

config t

int fa11

negotiation 10h

With these 2 changes, lets see if those 2 phones survive the reboot.

Let me know if you need more data from the files.

[Tom Watts]

Unless I missed it, I don't see fa24 going up or down but there is a duplex mismatch. Was port 24 a phone connection you changed the negotiation?

What ports did you change the negotiation on?

-Tom

[david.baumgarten]

I believe 24 is actually a small 4 port netgear switch plugged into a copier and an analog fax line converter ATA 186

I used port # 1 for 100 and port # 2 for 10. I am waiting another 15-20 minutes to see if they reboot.

David, any luck with reboots?

[david.baumgarten]

Sorry, was in a meeting.

Port 1 did not go down, port 2 did.

I have switched port 2 to 100f as well to confirm.

[david.baumgarten]

Port 2 went down

After further investigation, I noticed that some ports are drawing 2700-3000 mw and some are drawing 5300-5500mw. I suppose some of the phones might be different models (like the receptionist).

Port 1 is drawing: 2700mw

Port 2 is drawing: 5300mw

I went back through the log to see if Port 1 had actually ever went down but the log was truncated so I am unable to confirm.
