Powering on the system

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

About this task

Attention: Do not power on the system with any open bays or slots. Open bays or slots disrupt the internal air flow, causing the drives to receive insufficient cooling.

• Every unused drive bay must be occupied by a filler panel.
• Filler panels must be installed in all empty host interface adapter slots.

Note: The AC power supply unit, and the DC power supply unit in DC-powered models, features a cable retainer to secure the power cable.

Use the cable retainers to secure the power cables from being accidentally pulled out of the enclosure. The cable retainer, which is on the back of each PSU handle, has a curved opening that faces the rear of the PSU. After you plug the power cables in to the PSU, slip the power cable behind the retainer. Then, pull the cable back into the retainer opening to secure the cable.

Each cable must be routed through the retainer, as shown in Figure 1. For PSU 1, hook the power cable underneath the cable retainer so the cable can extend to the left. For PSU 2, make a loop to secure the cable under the retainer and extend the power cable to the right side of the enclosure.

To remove the power cable, push the cable forward to unhook it from the cable retainer. Then, unplug the cable from the PSU.

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 2).

   

   •  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 refer to Procedure: Understanding the system status using the 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.

   Notes:

   • Each enclosure has two power supply units. To provide power failure redundancy, connect the two power cords to separate power circuits.
   • Review the information on securing the power cables to ensure that each power cable is secured to each PSU on the back of the enclosure.
5. From the rear of the control enclosure, check the LEDs on each node canister. (See Figure 3.)

   

   •  1  Power
   •  2  Status
   •  3  Fault

   The canister is ready with no critical errors when Power is illuminated, Status is flashing, and Fault is off. If a canister is not ready, refer to refer to Procedure: Understanding the system status using the LEDs .
