Life Expectancy of Cisco Equipment

[joealcala]

Can anyone tell me what the lifetime expectancy (or MTBF) is of the Cisco switches. In particular, the 2950, 2970, and 3750. I can't seem to find any documentation on this.

I am researching the advantages/disadvantages of leasing vs. buying Cisco equipment, but I need to know how long these products are good for.

Thanks

Put it this way, you will be upgrading long before your equipment dies.

how will i know when my switch or router die?

[joealcala]

So if there are 8760 Hours in a year, looks like even the smallest MTBF is the 2970 and that would be roughly 18 years before a failure. OK, yeah its pretty safe to say I'll be replacing the equipment before then.

GP, where on the Cisco site did you find this information?

Thanks

[ianpdavis]

AFAIK if the MBTF is 18 years then there will be 1 expected failure for every 18 devices in the next year.

At least that is how I have always understood it.

Hello Joe,

the MTBF info can usually be found in the data sheet for the correpsonding device, as in the link below:

Cisco Catalyst 2970 Series Switch Data Sheet

HTH,

[joealcala]

Perfect.

Thanks.

hi all

which ios command can i use on the Switch to know how much time to reach the MBTF

[glen.grant]

there is no command that I know to show that . You can get uptime since last rebooted but that is about it.

Some of these models may have lifetime warranties, in which case Cisco brings them back to life if they happen to die ... so they're immortal !
