PS... There's this junction box in your machine room that has this

Do you understand that there are risks and there are improbable
risks?
We follow the @devops_borat Ops book and have a post-it-note on the
switch saying "not a light switch"
:D
Also we have a backup 4-port 1Gbe linksys router for when the main
switch fails. The biggest issue these days is that since we switched the
backplane to Ethernet over Powerline a power outage leads to network
partitioning even when the racks have UPS.
