That’s about the right failure rate for a population of 1000 switches. Enterprise switches typically have an MTBF of 700,000 hours or so, and 1000 switches operating 8760 hours (24x7) a year would be 8,760,000 hours. Divided by 12 failures (one a month), yields an MTBF of 730,000 hours. -mel

We probably swap a switch or two a month.... This level of failure surprises me. While I can't say I have 1000 switches, I do have hundreds of switches, and I can think of a failure of only one or two in at least 15 years of operation. They tend to be pretty reliable, and have to be swapped out for EOL more than anything.
