Powering the Storwize V7000 Gen1 system on and off

About this task

Follow the procedures for powering on the expansion enclosure and file modules, and in the order specified.

Attention: Do not operate the system when the drive assemblies are missing. Drive assemblies that are missing disrupt the airflow; the drives do not receive sufficient cooling. You must insert blank carriers into unused drive bays.

Powering on an expansion enclosure:

Power on the newly installed enclosures. Use the power switch on each of the two power supply units in the back of the expansion enclosure.
Use the information in Table 2 to verify the state of the light emitting diodes (LEDs) on the system. Verify that no faults are detected.

Both Figure 1 and Figure 2 show the location of the LEDs on the power supply units, located at the front of the expansion enclosure. Figure 3 shows the location of the LEDs on the power supply units, located at the rear of the expansion enclosure. The LEDs are located at position 1 .

Table 1. LED status front of control enclosure or expansion enclosure. Refers to item 1 in the figures above.
Hardware component	LED name and symbol	If power on and no fault is detected
Left enclosure end cap, front of enclosure	Power, top	LED is on.
	Fault, middle	LED is off.
	Identify, bottom	LED is off.

This figure shows the LEDs on the power supply units of the expansion enclosure.

Table 2. LED status rear of expansion enclosure.
Hardware component	LED name and symbol	If power on and no fault is detected
Expansion canister, rear. The reference to the top and bottom locations applies to canister 1, which is the upper canister. The LED locations are inverted for canister 2, which is the lower canister.	Canister status, top	LED is on.
	Fault status, bottom	LED is off.
	SAS ports	When a SAS port is functioning correctly, all four green LEDs above the port are on. If no cable is plugged into the port, or if the canister at either end of the cable is not yet fully started, the LEDs are not on.
Power supply unit, expansion enclosure. The reference to the left and right locations applies to power supply unit 1, which is the left power supply. The LED locations are inverted for power supply unit 2, which is the right power supply.	Power supply, upper right	LED is on.
	Fan failure	LED is off.
	DC power failure	LED is off.
	AC power failure	LED is off.

Powering on a control enclosure:

Power on the control enclosure, if it is not already powered on and configured. Use the power switch on each of the two power supply units, located in the back of the enclosure.
Use Table 3 to verify the state of the LEDs on the system. Verify that no faults are detected.

Figure 4 shows the location of the LEDs on the power supply units in the rear of the control enclosure.

Figure 4. LEDs on the power supply units of the control enclosure

This figure shows the LEDs on the power supply units of the control enclosure.

Table 3. LED status when control enclosure is powered on
Hardware component	LED name	If power on and no fault is detected
Left enclosure end cap, front of enclosure	Power, top	LED is on.
	Fault, middle	LED is off.
	Identify, bottom	LED is off.
Node canister, rear. The reference to the top and bottom locations applies to canister 1, which is the upper canister. The LED locations are inverted for canister 2, which is the lower canister.	Fibre Channel port	If the Fibre Channel port is used: One or more LEDs are on or flashing per port. The LEDs are located between the Fibre Channel ports. The arrow-shaped LEDs point toward the affected port.
	Ethernet port, if used	One or more LEDs are on per port.
	SAS ports	When a SAS port is functioning correctly, all four green LEDs above the port are on. If no cable is plugged into the port, or if the canister at either end of the cable is not yet fully started, the LEDs are not on.
	System status, left	LED is flashing or on. The status is on if the node canister is an active member of a clustered system. The LED is flashing if the node canister is in service or candidate state. If the LED is off, the node canister might still be booting up. Wait up to 5 minutes for the node canister to complete booting up.
	Fault status, middle	LED is off.
	Power status, right	LED is on.
Power supply unit, control enclosure. The reference to the left and right locations applies to power supply unit 1, which is the left power supply. The LED locations are inverted for power supply unit 2, which is the right power supply.	Power supply, upper right	LED is on.
	AC power failure	LED is off.
	DC power failure	LED is off.
	Fan failure	LED is off.
	Battery failure	LED is off
	Battery good, lower right	LED is on or flashing.

Attention: Do not go to the next section until the LEDs are in the required states. If any error lights are displayed, see the Storwize V7000 Unified Problem Determination Guide documentation CD for more information about light path issues.

File module power features:

When the file module is connected to a power source but is not turned on, the operating system does not run, and all core logic except for the integrated management module is shut down. However, the file module can respond to requests from the integrated management module, such as a remote request to turn on the file module. The power-on LED flashes to indicate that the file module is connected to power but is not turned on. The power on LED is found in the front of the file module.

Powering on the file module

Approximately 3 minutes after the file module is connected to power, the power-control button becomes active. Also, one or more fans might start running to provide cooling while the file module is connected to power. You can turn on the file module and start the operating system by pressing and releasing the power on button. The power on button is located at the front of the file module.

Turning off the file module

When you turn off the file module and leave it connected to power, the file module can respond to requests from the integrated management module. For example, it can respond to a remote request to turn on the file module. While the file module remains connected to power, one or more fans might continue to run. To remove all power from the file module, you must disconnect it from the power source.

Important: To view the error LEDs on the system board, leave the file module connected to a power source.

Some operating systems require an orderly shutdown before you turn off the file module. See your operating-system documentation for information about shutting down the operating system.

CAUTION:

The power on button on the device does not turn off the electrical current supplied to the device. The device also might have more than one power cord. To remove all electrical current from the device, ensure that all power cords are disconnected from the power source.

Press and release the power on button to start an orderly shutdown of the operating system and turn off the file module, if your operating system supports this feature

Attention: If you have a problem powering off the system, see the Storwize V7000 Unified Problem Determination Guide documentation CD for more information about light path issues.
