Connecting power cords to a 2U expansion enclosure

To power up a 2U expansion enclosure, install the power cords and check the status LEDs on installed canisters.

To power on the system, complete the following steps.

1. Power on all 2U expansion enclosures by connecting both power supply units of the enclosure to their power sources, by using the supplied power cables.
   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. Check the light-emitting diodes (LEDs) on each 2U expansion canister (see LEDS on 2U expansion canisters).
   Figure 1. LEDS on 2U expansion canisters

   • 1 Power
   • 2 Status
   • 3 Fault
   The canister is ready with no critical errors when Power is illuminated, Status is illuminated, and Fault is off. If a canister is not ready, refer to Procedure: Understanding the system status LEDs.
3. Wait for all 2U expansion canisters to finish powering on.
4. Power on the control enclosure by connecting both power supply units of the enclosure to their power sources, by using the supplied power cables.
   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. Check the LEDs on each node canister in the control enclosure (see Node canister LEDs).
