Failing Metered Rack PDU (AP7862)

[Anonymous user]

While working on one of our PDUs (AP7862), I was on the serial console navigating to the networking area, and the console became none responsive. I sat there and let it finish what ever it was doing in hopes it was just confused. It finally released, and put me back at the login prompt. I logged in again, started navigating to the networking area, and it locked up again (different spot of the menu). I waited and was presented the login prompt again. I once again logged in, and started navigating the menu, it locked up once again. This time I noticed the face panel on the PDU went to "88" and the three lights next to the display were all amber. It began flashing, and looked to have rebooted/reset.

While I was there watching it after it rebooted/reset, I noticed about 2 minutes later, it did the same thing again. This time I wasn't even on the console. It would cycle through each zone (2, then 3, then 4, then back to 2), and would eventually stop on one of the zones, then the NIC would start flashing, and the display would show "88" followed by what looks like a reboot/reset.

I removed the network cable, and serial cable and watched it. Within 2 minutes, the display showed "88" and the three lights went amber and it looked to reboot/reset again. Its continuously doing this.

I tried pushing the reset button and had the same results.

Before I make a service call, has anyone seen this before?

Thanks!

I'm not familiar with the AP7862 specifically, but when the network management card reboots in 2 minute intervals without a network connection, it may be corrupted data triggering a software bug (and the NMC reboots in an attempt to recover). If that's the case, a reset to defaults should fix it.

Of course you should try to get the data.txt and event.txt first.

Maurice,

Based from what you have described on your posts, it tells us that the PDU is rebooting. The PDU displays 88 on the display during intialization to verify that it is in working condition. If you could get in on the web interface or FTP I would try to gather the log files (i.e. data.txt and event.txt). I would also recommend power cycling the PDU, unplug it for a minute and plug it back in.
