Table 2 LED Failure/Fault Alerts

Online/activity LED (green)	Fault/UID LED (amber/blue)	Interpretation
On, off, or flashing	Alternating amber and blue	The drive has failed, or a predictive
		failure alert has been received for
		this drive; it also has been selected
		by a management application.
On, off, or flashing	Steadily blue	The drive is operating normally,
		and it has been selected by a
		management application.
On	Amber, flashing regularly (1 Hz)	A predictive failure alert has been
		received for this drive. Replace the
		drive as soon as possible.
On	Off	The drive is online, but it is not
		currently active.
Flashing regularly (1 Hz)	Amber, flashing regularly (1 Hz)	Do not remove the drive. Removing
		a drive may terminate the current
		operation and cause data loss.
		The drive is part of an array that
		is undergoing capacity expansion
		or a stripe size migration, but a
		predictive failure alert has been
		received for this drive. To minimize
		the risk of data loss, do not replace
		the drive until the expansion or
		migration is complete.
Flashing regularly (1 Hz)	Off	Do not remove the drive.
		Removing a drive may terminate
		the current operation and cause
		data loss. The drive is rebuilding,
		or it is part of an array that is
		undergoing capacity expansion or
		a stripe size migration.
Flashing irregularly	Amber, flashing regularly (1 Hz)	The drive is active, but a predictive
		failure alert has been received for
		this drive. Replace the drive as
		soon as possible.
Flashing irregularly	Off	The drive is active, and it is
		operating normally.
Off	Steadily amber	A critical fault condition has been
		identified for this drive, and the
		controller has placed it offline.
		Replace the drive as soon as
		possible.
Off	Amber, flashing regularly (1 Hz)	A predictive failure alert has been
		received for this drive. Replace the
		drive as soon as possible.
Off	Off	The drive is offline, a spare, or not
		configured as part of an array.

7-segment display board

The 7-segment display board allows you to identify the following:

•The port on the host controller to which the MSA70 is connected. There are two external ports on the host controller; each port allows you to connect up to two MSA70s to the controller. Because

one additional MSA70 can be attached to each of the MSA70s, a total of four MSA70s can be connected to the host controller. See Cascading (1+1) configuration.

•The box ID number assigned to the MSA70 based on how it is connected to the host controller. If there are multiple MSA70s attached to the controller, the box ID number identifies the order in which they are attached.

When the MSA70 is connected to the host controller, the controller automatically assigns the port and box ID numbers to the enclosure. The following table shows MSA70 enclosures and their associated port and box ID assignments:

Storage Enclosure	Port	Box ID
MSA70 enclosure 1	P1	B1
MSA70 enclosure 2	P1	B2
MSA70 enclosure 3	P2	B3
MSA70 enclosure 4	P2	B4

To view the port to which the MSA70 is connected, press the up arrow button on the 7-segment display board. To view the box ID number, press the down button.

15487

You can also view the port and box ID numbers within Array Configuration Utility (ACU), HP Systems Insight Manager (HP SIM), and Array Diagnostic Utility (ADU).

2 Powering up and powering down the enclosure

IMPORTANT:

Before installing this product, read the Important Safety Information document provided.

Powering up

Observe the following guidelines before powering up the enclosure:

•Install all components of the enclosure.

•Install hard drives in the enclosure so the connected host controller can identify and configure them at powerup.

•Always power up the enclosure first, and then the server. This ensures that the servers, during their discovery, see the enclosure as an operational device. If you do not power up the enclosure before powering up the servers, you will need to power down the servers, ensure that the enclosure is powered up, and then power back up the servers.

To power up the enclosure:

1.Complete server hardware installation and cabling. See the server documentation.

2.Connect the SAS cables and power cords to the enclosure. See Choosing a configuration.

3.Press and hold the Power On/Standby button. Wait and observe the system power LED and fan modules. When the enclosure powers up, the system power LED illuminates solid green and the fans spin to a high speed, and then spin down to a low speed.

4.Power up the servers. See the server documentation.

Powering down

CAUTION:

Be sure that the server is the first unit to be powered down and the last to be powered back up. Taking this precaution ensures that the system does not erroneously mark the drives as failed when the server is powered up.

IMPORTANT:

If installing a hot-plug device, it is not necessary to power down the enclosure.

To power down the enclosure:

1.Power down any attached servers. See the server documentation.

2.Press the Power On/Standby button on the enclosure. Wait for the system power LED to change from green to amber.

3.Disconnect the power cords.

The system is now without power.
