Spontaneously Rebooting MXP's

[Alexander-Leblanc]

Good Morning,

I have a bit of a stumper and was wondering if anyone could provide any advice - recently on our network our MXP's and SX series codecs have been spontaneously rebooting - we get the warning in TMS - "Boot". I have since found out that the SX's had an issue with any software below 7.3.6 and i haven't seen one reboot since the upgrade;however, the problem persists with MXP's.

The only changes i can think is that we have merged networks with another network as well as added a CUCM but i can't see how this would cause this to start happening.

I am wondering if anyone else has had this issue or has any ideas to brainstorm?

Thank you

That's a weird one - what were the SX20s on before your upgraded?

How often do they reboot or is there any pattern to it?

Is it possible to move 1 of the known offenders to a separate VLAN/LAN and see if it reboots?

Are they running on the voice VLAN or a seperate video VLAN?

If it was just SX20s, I'd guess the CUCM was trying to push out software updates, but since the MXPs are doing the same and they don't have the voice VLAN config it's wouldn't be that.

Hi Ray,

They were on 7.3.5 or lower from what i understand there was a bug that caused them to spontaneously reboot unless they were 7.3.6 - since the upgrades i haven't seen any other ones reboot from the SX series.

After a lot more investigation from other facilities we were able to determine that the MXP failures were due to coincidental power outages. Everything got tied up into the same thing because it all happened at the same time.

Thank you very much for your time - on a side note have you seen codecs unintentionally communicate with the CUCM?

Thank you again - have a great weekend!

Hi Alexander

The power outages make more sense :)

Regarding your question about unintentional CUCM communications, I haven't seen any issues with MXPs since they were always more Tandberg (i.e. Gatekeeper/VCS) oriented so they didn't look for TFTP settings.

With EX/SX/MX/CSeries units, in TC7.2(??) the Voice VLAN is enabled by default so we had some installations where the VC unit was picking up a voice VLAN IP address and getting SIP registration details from CUCM via DHCP. The fix then being to setting the unit to Voice VLAN off and configuring it as normal.
