As to network equipment getting "tired", or servers getting "tired", it's not so much that for either, it's more the case that newer technology offers much better performance than older equipment making the latter obsolete.
One major difference between the two, network technology often depends on much more than one device to be upgraded to take full advantage of newer technology. For example, before moving from 10 Mbps Ethernet to 100 Mbps Ethernet, every network device along a path might need to be upgraded; each end host, at least their NICs might need to be upgraded; and (often a very costly item) cabling might need to be upgraded. So, because of these issues, network devices might remain in active service longer than a server.
However, more like servers, some network equipment might be replaced sooner when "forklift" upgrades are not required. For example, the replacement of star configurations hubs with star configuration switches.
Unless and until network equipment breaks, it usually continues to deliver the same performance as when it did brand new.
