%SFF8472-5-THRESHOLD_VIOLATION: Te1/1: Tx power low alarm; Operating value: -40.0 dBm, Threshold value: -12.2 dBm
Hi,
I am facing a strange problem in one of my Cisco Catalyst 4900M switch. We have a ten gig WAN link which went down (error-disabled) couple of weeks back with logs suggesting Low TX power.
Tried followingtroubleshooting approach, but it did not resolve the problem.
SFP replaced
Tried connecting the link on a different port.
Fibers tested and found to be OK
Performed loop test and was able to see the loop on both end of the P2P link.
Replaced the Cables between PTT demarcation till switch patch panel.

Hello Friends,
i have catalyst 4503 series switch and i am trying to configure it, there is not any physical media connected to the switch yet.
but i have installed the X2-10GB-SM modules in its module (WS-X4606-X2-E)
without any cable or connectivity with other switches.
i am facing the error which is
%SFF8472-5-THRESHOLD_VIOLATION: Te3/1: Rx power low alarm; Operating value: -30.0 dBm, Threshold value: -18.4 dBm.

any idea to get off this problem?
thanksGents,
Looks like something is amuck as I just received a new 4507 as well and I am getting similar messages. Anyone have an idea as to what is going on? I too have not connected anything to this yet, just doing a burn in. I am installing into a cancer center and need to have this ready by the first.
regards,
Stephen

Hei
we have some switches that are connected with our nexus switches via SFP-10GLR. all switches are ok but only one is getting warnings in the logs saying: CET: %SFF8472-5-THRESHOLD_VIOLATION: Te1/1: Rx power high warning; Operating value: -0.9 dBm, Threshold value: -1.0 dBm.
all the SFP,s are same in alle switches.%SFF8472-5-THRESHOLD_VIOLATION Vs SFF8472-5-THRESHOLD_VIOLATION.
The first one is printed for the ports that are configured, but not connected/active.
You can avoid such error messages simply shutting down unused ports.
The latter indicates that there is a real threshold violation.
For more details on these error messages, check out.
http://www.cisco.com/en/US/docs/switches/lan/catalyst4500/15.1/XE_330SG/system/messages/emsg.html#wp1634341
Action Plan:
========
Can you please try clearing the interface counters, so that we can notice the frequency of errors.
Also I researched on the logs that we are observing on our device and have seen cases where the issue has been resolved by physically removing and reinserting transceiver.
Please refer below link for more details:

I have same issues on our network on all non Cisco X2 modules starting on nearly the same day (devices have nearly same update). I can't say that it is only cosmetic nature due to the fact that after a lot of these messages happened I registered SPT topology changes. This happened on several of my devices but it is not very often. For our customers it is a two second hit, where services are not available. Our software is on the 15.0 release train so a lot of possibilities to upgrade to higher versions are not given at this time.
Are in the above mentioned Cisco internal Bug (ID CSCth08212/CSCte94616) additional information which can be helpful but are not open to people outside TAC?
With kind regards

I forgot to mention that the message in my case describes a lot of temperature alerts (ranging from -130°C up to 130°C) that are violated and less of alerts belonging to the power. -

WS-X45-SUP8-E: %SFF8472-5-THRESHOLD_VIOLATION
Hello,
I got a WS-X45-SUP8-E Core switch with TenGigabitEthernet ports.
one of the port on the core give the following error:
%SFF8472-5-THRESHOLD_VIOLATION: Te5/4: Rx power low warning; Operating value: -12.4 dBm, Threshold value: -9.9 dBm.
The other switch connected on this link doesn't.
It also doesn't seem like a Bug because the rest of the port are up and running just fine, same switches and SFP.
I already changed the SFP and patch kabels.
any ideas??
Thanks.Hello,
i changed the patches between 2 switches and now we got the error on a other switch. so the fiber between the core and access switches is giving the problems.
in the on coming weeks where going to replace the fiber cable.
MANY THANKS!!! -
Cisco 2960S SFF8472-5-THRESHOLD_VIOLATION
Hi All
I have a issue connecting my Cisco 3750X 12 port fibre switch to my Cisco 2960S 24Port switch using Multi Mode Fibre.
I have Mode condtioning cables connecting to the SFP (GLC-LH-SMD) on the 3750 via a fibre patch panel which bring me to the 2960s with its Mode conditioning cable and SFP (GLC-LH-SMD).
The fibre port on the Cisco 2960S was up for all of 10 mins and has gone out with the following error message.
%SFF8472-5-THRESHOLD_VIOLATION: Gi1/0/26: Rx power high warning; Operating value: -2.7 dBm, Threshold value: -3.0 dBm.
I did a show int transceiver command and got the following output.

Optic power levels - %SFF8472-5-THRESHOLD_VIOLATION
Can some explain this to me...
%SFF8472-5-THRESHOLD_VIOLATION: Te1/0/1: Tx power low alarm
If I am getting a LOW TX alert the issue can't be with the fibre and it has to be something do to with the optic / line card / software or chassis. I presume DOM is reporting this before the light is put onto the link... as in before it even touches the fibre.
Any help is much appreciated.Hi
It could be a bad transceiver. Did you try reseating the transceiver once?
If not helping please try replacing it and check.
Thanks,

Hi all,
I'm running on cisco 3750E series switch stack and getting following errors in log
"SFF8472-5-THRESHOLD_VIOLATION: Gi2/1/2: Rx power low warning; Operating value: -19.4 dBm, Threshold value: -17.0 dBm"
There are two ports in this module and other one is working fine. Can any one suggest a troubleshooting process for this regards .
Thanks in advance.
Best regards,
Nimoda BandaraFirst troubleshooting step - upatch each connector in the path and clean the fiber ends using a fiber cleaning kit. Check the Rx power levels after each repatch ("show int trans det gi2/1/12")
Second step - if that doesn't fix it, have your cabling vendor come in and test the optical loss of the end-end link. Replace or repair and faulty connections or links. -
SFF8472-5-THRESHOLD_VIOLATION
Hello,
I have a switch 3750X connected to a nexus 5000 via DWDM SFP (C3KX-NM-10G). The IOS of the 3750X is universalk9 12.2(58)SE2 and of the Nexus 5.2(1)N1(2a).
I get all 10 seconds on the 3750x the following error:
%SFF8472-5-THRESHOLD_VIOLATION: Te2/1/2: Rx power high alarm; Operating value: -1.7 dBm, Threshold value: -6.0 dBm.
When I add a buffer attenuator, nothing changed.
Is this a bug of cisco or what can I do?

I have a switch 3750X connected to a nexus 5000 via DWDM SFP (C3KX-NM-10G). The IOS of the 3750X is universalk9 12.2(58)SE2 and of the Nexus 5.2(1)N1(2a).
I get all 10 seconds on the 3750x the following error:
%SFF8472-5-THRESHOLD_VIOLATION: Te2/1/2: Rx power high alarm; Operating value: -1.7 dBm, Threshold value: -6.0 dBm.
When I add a buffer attenuator, nothing changed.
Is this a bug of cisco or what can I do?

T510 Battery Power Low.. Plug in power issues
I move from location to another location disconnect the power and then reconnect the power on laptop T510.
After a few hours’ work I get the message “Battery Power Low.. Plug in power”
The power adapter was plugged in from the start… All I do us remove the power connector and re-attached.. Then all is OK..
The battery icon in lower screen shows 97% available (plugged in, not charging)
Finding this scarey.. If I have a bettery or power failure at customer remote site.. I'm a telecom field engineer...That's no problem at all PKcool.
Here are the drivers you will need to install on your computer:
Power Manager for Windows 7:

ThinkPad Power Manager Patch module for Windows 7:
http://support.lenovo.com/en_US/downloads/detail.page?DocID=DS018811
I would suggest going into your Programs and features and uninstalling the Power Manager from your computer, same goes for the drivers associated with it in device manager.
Once uninstalled I would then download the drivers from the links above. This will give your computer a fresh install of these drivers.
Please let me know of the progress.
Hope this helps,
Alex

Rx Power Low on ME3400/1000BaseLX
We just had a new run of fiber patched into our cage and along with it, we installed a new SFP (non-Cisco, GLC-LH-SM-C2G) into our ME-3400EG-2CS-A (12.2(58)SE2). After installing the SFP I changed the media-type to SFP and can confirm through interface capabilities and interface status, that the transceiver is detected properly:
Port Name Status Vlan Duplex Speed Type
Gi0/2 notconnect routed full 1000 1000BaseLX SF
However, as you can see, there appears to be a Layer 1 issue causing the interface not coming up. The fiber is terminated into our cage using SC connectors, so we have a patch to LC. We have done some loopback tests to the other equipment and the interface comes up and we get good readings, before and through the patch. The run is only 535ft between the devices, so the long haul SFP is overkill but I wasn't able to identify any single mode short run SFPs, so LH/LX is what I went with. However, when we run the loopback to our new SFP, the interface doesn't come up.
That all being said, I am thinking that the SFP is just bad. We are going to be swapping it out as well as trying a Cisco brand and as a last resort a SC fiber media converter to go to copper to the switch and eliminate the LC patch. I just wanted to see if there were any other thoughts/things I might be missing. I don't have a lot of experience with fiber so I couldn't really pinpoint anything else outside of a faulty SFP.
My trans details are as such, indicating a Rx power issue:

Receive Power Threshold Threshold Threshold Threshold
Port (dBm) (dBm) (dBm) (dBm) (dBm)
Gi0/2 -40.0 -2.0 -3.0 -20.0 -21.0
Also, just in case, I did run the "service unsupported-transceiver" command to no avail.
Thanks in advanceFirst troubleshooting step - upatch each connector in the path and clean the fiber ends using a fiber cleaning kit. Check the Rx power levels after each repatch ("show int trans det gi2/1/12")
Second step - if that doesn't fix it, have your cabling vendor come in and test the optical loss of the end-end link. Replace or repair and faulty connections or links. -
I saw some (--) low alarms on my optics.
I'm wondering if these alarms can cause any kind of problem.
Has anyone experience ?

I'm beginning to really agree with you about this board. I realise I'm no expert as gaming stuff, but i've working in IT for over 10 years and dealt with a lot of stuff and this really had been one of the worse experience from start to finish that i've had.
Jeez I don't know why you guys bought the board in the first place.. maybe cuz its the cheapest 975x board out???Of course don't expect as much as Asus Deluxe Home!

Coupled with the fact my RAID controller has never worked, niggles like the 'floppy drive error' (which you have to override in the BIOS)
Sure it's going to complain if a floppy drive is enabled in the bios but not connected? Makes sense, what's the big deal?

At least you go your board OCing a bit ... despite having OCZ 800mhz memory 5-5-5-12 / 2.0v ... these settings just cause the BIOS to not restart ... I can't get 800mhz.
Try using different a BIOS and setting your memory timings manually. I've found my system works best with the older BIOS. Yours may be the same?? Using WinFlash its really easy to change the BIOS. Give it a try, experiment
Sorry haven't tried RAID.
And FrobinRobin, set your CPU voltage to 1.58V, mem to 5-5-5-15 2.2V, PCI-E voltage to 1.7V and then see if you can get over 400FSB. If all is well then tighten your settings. First you may want to boot to windows at 380FSB then use ClockGen to increment the FSB from within windows. -
Just got a KT4V motherboard, with Athlon XP2100, 256MB PC2700 SDRAM.
Everything runs fine for an hour or so, and then the PC abruptly turns off accompanied by a high/ low alarm sound which continues until I unplug from mains and restart.
I am assuming this is a high temp shut down, but can find no mention of it in the manual/ website to confirm this, and the temp monitor is reporting only 40 degrees.
Any one got any suggestions?Thanks for your thoughts.
I checked the cooler, which was located correctly (hopefully gone passed that level of mistake now), but noticed, as I picked up the PC to have a look, it truned off again with the alarm going.
Rebooted, tapped the PC on the top, alarm goes of. Does the motherboard have a state of the art anti theft movement sensor built into it? I was beginning to think to myself.
So, rebuilt PC thinking stay screw got under the motherboard causing it to short or that sort of thing, but same problems afterwards, so I replaced the power supply and now everything is working OK.
Stange thing is though, the power supply works fine in another PC with similar spec (but non-MSI) motherboard, no mattger how hard you bang it!
Thanks for help anyway.
