We have about 20 Cisco Catalyst 2950 switches (24 port, for what it is worth). They range in age from 3 to 5 years old. They have been completely trouble free so far.
I'm trying to plan for the next three to five years. A lot of businesses seem to upgrade pc's every three years and a lot of schools seem to upgrade PC's every five. Is there a rule of thumb for replacing switches, assuming no technical need? Are there technical concerns I should think about in terms of performance?
I hate to replace them just to replace them if they are working fine.
It appears from the web site that Cisco will quit doing firmware supports 12/2007. We don't carry any service contracts on them. Any additional thoughts on the subject would be appreciated.
