The second life for network equipment. Most manufacturers won’t necessarily tell you the exact fail rate on new products. But if you look to vendors of used Cisco hardware, all of the good ones stand by their refurbishing process and tell you the reliability rating of their offerings.
However, if you opt to utilize refurbished network equipment specially CISCO equipment with its reduced price, you could give yourself much better options when it comes to hot, swappable spares. And that’s just a happy thought!
