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.- Every unused drive bay must be occupied by a filler panel.
- Filler panels must be installed in all empty host interface adapter slots.
Open bays or slots disrupt the internal air flow, causing the drives to receive insufficient
cooling.
Procedure
To power on the system, complete the following steps.
- 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.
- From the rear of the expansion enclosure, check the LEDs on each expansion
canister (see Figure 1).
Figure 1. Expansion canister LEDs
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 using the LEDs
.
- Wait for all expansion canisters to finish powering on.
- 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.
- From the rear of the control enclosure, check the LEDs on each node canister (see
Figure 2).

illuminated, Status is flashing, and Fault is off. If a canister is not ready,
