Data Center 101: Avoid Accidental Power Cord Disconnections

July 12, 2017 Tripp Lite

The Uptime Institute estimates that human error causes roughly 70 percent of outages in data centers today.  Here's a simple solution to keep power cords from being unplugged: color-coded power cord plugs and plug inserts take the guesswork out of your data center and ensure that staff always know the priority of power connections.

Prevent plug from being unplugged
  • A device connected to a RED power cord plug is mission-critical and should never be unplugged
  • Equipment connected to a YELLOW power cord plug should not be unplugged without management confirmation. The device may be mission-critical with a redundant power supply, allowing one input cord to be disconnected as long as the other is still connected.
  • A device connected to a GREEN power cord plug is not mission-critical and can be unplugged temporarily if necessary.
