Bad 6509

[dlots]

We had a 6509 go bad over a reboot last Friday: the system just wouldn't come back up.  After lots of trouble shooting and several RMAs we found we had
1 bad chassis
2 bad sup 720s
1 bad 10gb fiber line card
1 bad 48 port GE card
Not everything in the chassis, but quite abit.  I have never seen that much stuff crap out... espeshally for a reboot.

Gonna try and get them to do the Cisco GOLD thingy next time (basically runs the POST test while the system is running to make sure it will come back up.

That was the only thing I hated about our 7600's. A reboot could instantly change a maintenance window. Only had one or two modules at a time though. You sir might hold a record now.

Yeah, that's a tough set of crap to hit your fan.

Is the Cisco 6500 Series invincible?

Holy crap!

I've had 50% of the line cards fail on me before thanks to this little gem. The fault doesn't reveal itself until reboot, the faulty module can run for years without any noticeable symptoms.

NEVER. EVER. UPGRADE.

Interesting. How does the unit still go on functioning when the memory goes bad? Pretty clever.

[wintermute000]

Its some kind of electrical tolerance thingy so the blades run fine in normal operation with normal electrical supply specs, then when subjected to startup/reload voltages or amps (don't ask me I'm no sparkie!) it craps out.


I talked to a few guys from my former MSP after I got nailed by it and they told me that at one point they had a level 1 grunt doing almost nothing but replacement calls for this particular fault, reckon they had several come in every night for a year or two. Because the ROMMON output is so specific its easy to nail it down to this bug.

We got hit with this memory component bug pretty hard in our 28xx router fleet, and I'm afraid every component in our 6509 is going to suffer the same thing on the next reload.

[Dieselboy]

So it's not just specific to the 6509 either?

DDAAAMMNNN!!!!!

That is not what you'd expect of a simple reboot.

And now you know why there are several zillion Windows XP boxes around the world, running business-critical applications, with brilliantly-colored post-it notes slapped on them, bearing the stern warning, "DO NOT REBOOT!"
