[c-nsp] Question regarding 6500

[Hudson Delbert J Contr 61 CS/SCBN]

have to agree as we have a slew of them and to extend it, i'd venture
a guess that MOST enterprise switch failure modes are connected to blade or
linecard 
failures as opposed to other chassis or components.

Dear Vish,

We have 2 Cat6509's (for redundancy purposes) at our company and they're
doing more than very well. To be exactly....we NEVER had any problems with
any hardware but, of course, this doesn't say that it's representative for
all 6500-series Catalysts. I think that most of the downtime due to
defective hardware is caused by the blades. Second cause is a poorly
network-design. Personally I don't think you'll find someone who has two
defective cat6509-powersupply's at the same time, but allways keep a spare
for emergency purposes. I really don't think you can describe the chances of
failiure by any numbers.

Best regards,

Duncan Stork

Sorry for the spam. I am trying to find this info, but can't find it
anywhere. So posting my question to a wide and experienced audience.

What are the chances of dual Sup 6500 chassis going down completely for
whatever reason in general or hardware failure in particular. Anyone has
MTBF for 6500 with dual everything (power supply, sup)?

You may reply to me off list.

Thanks.

Vish.
