Installing hardware options. HP MSA70 Array

3.

Slide the chassis into the rack.

4.

Use the thumbscrews on the front of the chassis to secure it to the rack.

5.

Use the shipping bracket to secure the enclosure for shipping:

IMPORTANT:

Use of the shipping bracket is required only when the rack is shipped with the enclosure installed.

a.

Loosen the thumbscrew on the shipping bracket.

b.

Slide the shipping bracket forward until it engages the chassis.

c.

Tighten the thumbscrew.

If you are installing the enclosure into a telco rack, order the appropriate option kit at the RackSolutions website: http://www.racksolutions.com/hp . Follow the enclosure-specific instructions on the website to install the rack brackets.

Installing hardware options

Install hardware options, such as an additional I/O module, before initializing the enclosure. For installation information, see the documentation shipped with the module.

Installing disk drives

Disk drive options

The enclosure supports up to 25 SAS or SATA disk drives.

A variety of disk drive models are supported for use, including dual-ported and single-ported disk drives. For more information about supported disk drives, see the QuickSpecs for the disk enclosure, available on the MSA70 website.

Disk drive guidelines

When adding disk drives to the enclosure, observe the following general guidelines:

70 Modular Smart Array User Guide 19

• Follow industry-standard practices when handling disk drives. Internal storage media can be damaged when drives are shaken, dropped, or roughly placed on a work surface.

• When installing a disk drive, press firmly to make sure the drive is fully seated in the drive bay and then close the latch handle.

• When removing a disk drive, press the release button and pull the drive only slightly out of the enclosure. Then, to allow time for the internal disk to stop rotating, wait approximately 10 seconds before completely removing the drive from the enclosure.

• The system automatically sets all device numbers.

• Always populate disk drive bays starting with the lowest bay number. If only one disk drive is used, install it in the bay with the lowest device number.

• Drives must be the same capacity to provide the greatest storage space efficiency when drives are grouped together into the same drive array.

• Disk drives are hot-pluggable.

• SAS and SATA disk drives may be installed in the same enclosure, but can not be included in the same RAID logical volume.

Installing a disk drive

CAUTION:

To prevent improper cooling and thermal damage, operate the enclosure only when all bays are populated with either a component or a blank.

1.

Remove the drive blank.

2.

Press the latch and slide it to the right to disengage the lever (1), and then open the lever (2).

Make sure that the lever is in the fully opened position before inserting the drive into the bay.

3.

Slide the disk drive into the bay (1), pressing firmly on the drive to seat it. Close the lever (2), pressing firmly until it locks in place

IMPORTANT:

When the drive is inserted in an operational enclosure, the drive LEDs flash for 2 seconds to indicate that the drive is seated properly and receiving power.

4.

Determine the status of the disk drive (see

Hard drive LED combinations

).

IMPORTANT:

For proper airflow and cooling, a blank must remain installed in all unused drive bays.
