8608GBE failure

[telecom116]

Has anyone had a complete failure of a 8608GBE module in a Passport 8600 system? This afternoon I suddenly lost the complete blade; the LEDs were all amber. Pulling and reseating the blade caused the entire blade to be dead.

Luckily, I only had two GBICs in the blade, and I had enough spare equipment to at least get them both up and running. I don't have another free slot to test it in, but at least I have a contract with Nortel, so a replacement is (hopefully) on the way.

Anyone else experienced anything at all like this on a 8600? The whole Passport is new, only used 1 1/2 months.

Hi

Sounds like a failure of the processor/memory on the card itself, causing it to hang with all the amber LEDs. There is also a DC-DC convertor on each card. if this fails all the LEDS will go out.

Reseating the card should cause it to re-run the Power-on Self-test. If the card's processor or clock fails then this will not start, and the state of the LEDs will be uncontrolled.

Either of these is pretty rare, but they can & do happen

Thanks for the info. I got a replacement blade today, going in later tonight to put the fiber back where it came from.

At INNMUG conference last year, there was several in the group who discussed Nortel's out-of-box failure rate. With this short service time, this is nearly out-of-box unit (I have a 2 yr. old 8600 that has never had a problem). Recently I had a new BPS 2k that was an out-of-box failure. They really need to work on QC if they want to compete in the enterprise market in the future.

Dear telecom116,
Comparing Cisco and Nortel for reliabilty, it is a one horse race, Nortel wins hands down.
We have 400+ 450/BPS/460 edge switches and 18 core 8600 switches.
We get more failures on our Cisco wireless LAN, where we have 10 WAPs.

I do agree that out-of-box failures show poor QC.
We had a replacement BPS arrive, we upgraded the code, loaded our template config and when we went to screw in the rack mount screws, discovered that the chassis had been assembled WITHOUT nuts


Cheers,
Ewey.
