We recently had a sporadic reboot of a distribution switch for an unknown reason. No recent hardware/software changes have been made. Our log files don't indicate anything leading up to the incident.

The system is a 6509-E running software version 15.1(1)SY on both active and backup supervisor modules.

The system had a primary and backup supervisor card (SUP720) running in SSO. The system was actively functioning in Standby Hot, but the Backup RP never took over as the Active RP, which caused a complete system reboot.

The backup RP eventually booted back up and came back online with the most recent configuration, but the primary supervisor card slot won't boot any cards. We replaced the card with the same card model with no luck. The cards were all tested on a backup 6509 chassis, all of them booted without any issues; which eliminates the possibility of a faulty card.

When trying to boot the cards on this chassis, this is as far as we get:

It doesn't get any further. When we check the active RP, it shows the card is attempting to come online but never fully boots.

    keep_alive threshold = 19
           RF debug mask = 0x0

Any suggestions on how to fix this? Or is the chassis defective?


show module reaffirms that the card isn't recognized by the system.

  • Just a few questions which might make it more likely to get some useful answers: 1. Are you able to login on the console on the standby sup? 2. what does 'show module' on the active sup say about the standby? 3. what do the logs on the active sup say about redundancy and the standby sup? 4. what does 'show redundancy' on the active sup say? 5. are you booting the standby sup with identical bootloader and IOS versions as the active one? – Teun Vink Nov 24 '13 at 18:17
  • @TeunVink I can't log in to the standby supervisor card when trying to boot it up. Above, where the boot information is shown, is as far as it gets. Both cards are on the same version, both were previously on this version. As previously stated, there haven't been any changes to the system; to include logical and physical. – Ryan Foley Nov 25 '13 at 18:42
  • How much time did u give it? It can take well over 30 minutes to get from standby cold to standby hot. And show logging and show tech will give more useful information. I don't see anything wrong from what u posted except patience. SUP720 is slow... – sdaffa23fdsf Nov 28 '13 at 9:05
  • @realdreams I gave this a couple days to start up, it just hasn't come back online. No supervisor card that I've ever worked with takes over 30 minutes to initialize and sync. When upgrading the images, it generally only takes around 10 minutes from zero to hot-standby. On our spare chassis, it came online in under 10 minutes; just takes a while to boot-up, the SSO sync only takes a few seconds. – Ryan Foley Nov 28 '13 at 9:50

Based on what you describe and tested I'd expect the slot on the chassis to be broken.

  • 1
    That's been my working assumption as well. I think the OP needs to consider that as a solid possibility – Mike Pennington Nov 28 '13 at 11:17
  • @MikePennington This was my assumption as well. I've been routing a change request through our different organizations to replace our primary chassis with a backup we have in storage. – Ryan Foley Nov 28 '13 at 11:23

Try swapping the Sup Cards and see which will come up. If the primary one works in the slot of the backup, then you will have to RMA the device.

  • 1
    I already did that. From the OP: "We replaced the card with the same card model with no luck. The cards were all tested on a backup 6509 chassis, all of them booted without any issues; which eliminates the possibility of a faulty card." We also won't be able to RMA the device, this chassis is over 8 years old. – Ryan Foley Nov 29 '13 at 21:09
  • Well, in that case you will have to upgrade the device. It sounds like a faulty back panel .. Why don't you open a Cisco TAC? This can help you identify the fault better – sikas Dec 1 '13 at 5:31
