3750x with 7965 with Jabra motion

[joeclarktx]

We have an odd case.  In our environment, we try to create open offices spaces where users can work at any workstation.  Plug in a laptop and use their own headset to work for the day, and the sit in another area another day.  With this setup, we have standardized on:

- 3750x switches (will be 3850 this year)

- Cisco 7965 phones (will be an 88xx this year)

- Jabra motion office (or pro)

-Targus port replicators

What is happening, from time to time, the phones in one area will all go dead, no power what so ever.  We were able to get logs that lead us to this bug:

https://quickview.cloudapps.cisco.com/quickview/bug/CSCsw18530

We have tried all the workarounds, with nothing working.  There are only two ways to get the phones to power up:

1.  Shut/no shut the ports - this does not work every time

2.  Manually pull the EHS cable from the back of the phone, until we find the malfunctioning unit, and at that point all the phones power up. or pull the usb cable from the docking station to the headset cradle.

If this happens in the same area, it is hardly ever the same phone/headset dock.  We have been on with TAC and probably have 10 cases open.  We will be testing out a newer software version as soon as they send it.

I am really hoping that someone else has a similar setup that is experiencing something similar to what we are seeing.  We have had cases opened with Cisco, Targus and Jabra, and each is blaming the other (with the exception of the bug)

Hold on ... This doesn't make sense.  Where did this information about the Bug ID come from?  Know Affected Release states 12.2(46)SE but there is a snowballs-chance-in-h3ll anyone can load 12.2(46)SE into a 3750X and get the appliance to work.  3750X is NOT compatible to 12.2(46)SE.  TAC should know this.  

Please share the "sh logs" and IOS version the switches are running on.  I also want to see the output to the command "sh interface <BLAH>" and "sh controll e <BLAH>" of the phone ports when it happens.

Happened this morning, here is the info:

InfoSec team wasn't keeping logs of access switch and log buffer was not large enough to get too much detail this time, will post more from log when it happens the next time

Best I got from the log was:

Mar 31 12:19:13: %PLATFORM_ENV-1-FRU_PS_ACCESS: FRU Power Supply is not responding

[Leo Laohoo]

No line errors so I'm suspecting this is fine.  

Please try a different IOS.  15.2(3)E3 is available. 

I'm no VoIP guy but check the firmware of the phone against the Release Notes to see if there are any known compatibility issues with Jabra.

[joeclarktx]

Switches have been upgraded to 15.2(4)E1 as recommended by TAC.  After the upgrade we had a number of phones in a down state.  Once we walked the floor and unplugged the EHS, all the phones came up.

While it doesn't sound like it worked, I won't say it's broken until i have another failure after the switches have been running on this code for some time.

Will update this week.

[joeclarktx]

We just had the same issues again.  Phones were powered down when I came in the office this morning.  

Walked around the floor removing the EHS cable until the phones came up.

trying to get logs, and will post if I have anything.
