Connecting AC Power Cables to Chassis

To connect AC power:

  1. Make sure the circuit breaker at the mains is off.

  2. Insert an AC power cable into each AC power inlet on the rear-bottom of the Chassis.

AC Power Configuration for Maximum Power Resilience:

Best Practice - For increased power availability, we recommend to use redundant power circuits with a Dual Chassis configuration.

A redundant power circuit has a second circuit path that keeps power to the Chassis in case of failure of one of the power circuits.

For maximum resilience against power failure, use two power circuits and three Power Supply UnitsClosed Hardware component that supplies AC power with filtering and over-current protection. Acronym: PSU. (PSUs) in each Chassis.

In each Chassis, connect three PSU to one power circuit, and two PSUs to the other power circuit.

Example:

  • Chassis A contains 3 PSUs: A1, A2, A3.

  • Chassis B contains 3 PSUs: B1, B2, B3.

Connect the PSUs to the Power Circuits as follows:

  • PSUs A1, A2, B3 to the Power Circuit X.

  • PSUs B1, B2, A3 to the Power Circuit Y.
