Powering on the system

After you install all hardware components, you must power on the system and check its status.

To power on the system, complete the following steps.

1. Power on all expansion enclosures. Use the supplied power cords to connect both power supply units of the enclosure to their power sources.
   If the power sources have circuit breakers or switches, ensure that they are turned on. The enclosure does not have power switches. Repeat this step for each expansion enclosure in the system.

   Note: Each enclosure has two power supply units. To provide power failure redundancy, connect the two power cords to separate power circuits.
2. From the rear of the expansion enclosure, check the LEDs on each expansion canister (see Figure 1).

   • 1 Power
   • 2 Status
   • 3 Fault
   The canister is ready with no critical errors when Power is illuminated, Status is on, and Fault is off. If a canister is not ready, refer to Procedure: Understanding the system status LEDs.
3. Wait for all expansion canisters to finish powering on.
4. Power on the control enclosure. Use the supplied power cords to connect both power supply units of the enclosure to their power sources.
   If the power sources have circuit breakers or switches, ensure that they are turned on. The enclosure does not have power switches.

   Note: Each enclosure has two power supply units. To provide power failure redundancy, connect the two power cords to separate power circuits.
5. From the rear of the control enclosure, check the LEDs on each node canister (see Figure 2).
