1 Enclosure Features The HP StorageWorks Modular Smart Array 20 (MSA20) is an Ultra320 host connect disk drive enclosure that uses Serial ATA (SATA) drives. The MSA20 delivers a low-cost, high-capacity solution that is suitable for minimum I/O workload situations such as storing reference data, archiving files, and performing disk-to-disk backups. You can connect the MSA20 to the external port of any sixth-generation Smart Array controller or to an MSA1500 controller shelf (MSA1500 cs).

3 Installing the Enclosure in a Rack Installing the enclosure in a rack involves four steps: • Preparing the rack • Removing the enclosure components to make the enclosure more manageable • Mounting the enclosure in the rack • Completing the installation process (reinstalling the components and connecting the power) Preparing the Rack The racks that HP supports for use with the MSA20 enclosure are the HP System E racks and the HP 10000 Series racks.
Installing the Enclosure in a Rack • Controller module—Squeeze the finger hook and the release lever together while pulling the module out of the enclosure. • Disk drive—Press the release button, and then pull the release lever to remove the drive from the enclosure. • Drive blank—Squeeze the release latch while pulling the drive blank out of the enclosure. • Fan assembly—Lift the release lever upward while pulling it to remove the fan assembly from the enclosure.
Installing the Enclosure in a Rack b. Push the template tabs into the holes in the rack uprights to hold the template in place. c. Use a permanent marker pen to indicate the holes in the rack uprights into which the scissor-like locking latches are to be inserted, as specified by the template. d. Repeat these steps to mark the back of the rack, using the information on the back of the template as a guide to the required location of the locking latches in this case. 2.
Installing the Enclosure in a Rack 4. Slide the front end of the right rack rail toward the inside front of the rack until the locking latch engages with the marked hole in the front rack upright. 5. Extend the back end of the rail toward the inside rear of the rack until the locking latch engages with the marked hole in the rear rack upright.
Installing the Enclosure in a Rack 6. Loosen the locknut on the shipping bracket (1), and move the bracket to the rearmost position on the rail (2). 7. Repeat steps 4 through 6 for the left rack rail. 8. Align the enclosure with the rails, and slide it into the rack.
Installing the Enclosure in a Rack 9. Remove the mounting bracket covers (1), and tighten the thumbscrews to secure the enclosure to the rack (2). 10. Replace the mounting bracket covers. 11. If you intend to move the rack while the enclosure is installed, adjust the shipping brackets on each rail to secure the enclosure to the rack. a. Loosen the shipping bracket locknut (1).
Installing the Enclosure in a Rack b. Slide the bracket forward until it engages with the enclosure chassis (2). c. Tighten the locknut. d. Repeat this procedure for the other rail. Completing the Installation 1. Reinstall the components in the enclosure. For details, refer to Chapter 5. 2. Connect the VHDCI connector on the controller module to the output of an MSA1500 cs or to the external connector of a sixth-generation Smart Array controller in a server. 3.
Installing the Enclosure in a Rack — In the case of a drive, it is predicted to fail in the near future (assuming that it is seated properly in the enclosure). — In the case of a power supply, it is not plugged in.
4 Configuring the Enclosure Drives The following tools are available for configuring the drives in an MSA20 enclosure: • The HP Array Configuration Utility (ACU)—A versatile, browser-based utility that provides you with maximum control over the configuration parameters • The HP Option ROM Configuration for Arrays utility (ORCA)—A simple ROMbased utility that runs on all operating systems • The MSA1500 cs Command Line Interface (CLI)—A tool for configuring and managing an MSA1500 cs and its attached st
5 Replacing Enclosure Components All components are hot-pluggable. However, removing a component causes a significant change in the airflow within the enclosure, and the enclosure could overheat if a replacement component is not installed within a relatively short time. • Before removing a component from the enclosure, be sure that a replacement component is immediately available. • If removing a drive, replace it with another drive or a drive blank to maintain the correct airflow in the enclosure.
Replacing Enclosure Components 4. Install the replacement component in the enclosure. 5. Observe the status LED of the replacement to confirm that the new component is operating properly. 6. Place the defective component in the static-free container for shipment. Disk Drive or Drive Blank Removing a Drive Blank Squeeze the release latch and hold it in while pulling the blank out of the enclosure. Removing a Disk Drive 1. Press the release button. 2.
Replacing Enclosure Components 2. Insert the replacement drive into the bay until it can go no further. About 1 cm (0.5 inch) of the drive protrudes from the bay. 3. Push the release lever all the way in. This action installs the drive completely in the bay and seats it firmly against the connector in the enclosure. 4. Observe the drive status LEDs to confirm that the replacement drive is functioning correctly. Fan Assembly 1. Lift the release lever and pull the fan assembly out of the enclosure. 2.
Replacing Enclosure Components 5. Insert the replacement controller module into the enclosure until it is firmly seated in the enclosure. 6. Connect the VHDCI cable to the connector on the new controller module. CAUTION: To prevent damage to the cable connector, do not use excessive force when tightening the thumbscrews on the connector. 7. Confirm that the status LED on the replacement module is illuminated green.
Replacing Enclosure Components 3. Slide the battery unit toward the rear of the controller module and lift it out. 4. On the back of the battery unit, push the two plastic retainer tabs upward through the slots in the battery case (1). 5. Tilt the battery pack slightly away from the battery case (2). 6. Press down on the battery pack to expel it from the battery case (3). To install the replacement upper battery pack, reverse the previous steps.
Replacing Enclosure Components To replace the lower battery pack: 1. Remove the upper battery unit. (You do not need to dismantle the upper unit unless you must also replace the upper battery pack.) 2. Remove the cache board. a. Open the ejector levers on each side of the memory module socket (1). b. Pull the cache board out of the socket (2). 3. Push the plastic retainer tabs through to the other side of the cache board (3). 4. Lift the battery pack off the cache board.
A Regulatory Compliance Notices Federal Communications Commission Notice Part 15 of the Federal Communications Commission (FCC) Rules and Regulations has established Radio Frequency (RF) emission limits to provide an interference-free radio frequency spectrum. Many electronic devices, including computers, generate RF energy incidental to their intended function and are, therefore, covered by these rules.

Regulatory Compliance Notices Japanese Notice Korean Notices HP StorageWorks Modular Smart Array 20 User Guide A-5
Regulatory Compliance Notices BSMI Notice Battery Replacement Notice The controller cache uses a nickel metal hydride (NiMH) battery pack. WARNING: There is a risk of explosion, fire, or personal injury if the battery pack is not properly handled. To reduce this risk: • Do not try to recharge the batteries if they are disconnected from the controller. • Do not expose the battery pack to water, or to temperatures higher than 60°C. • Do not abuse, disassemble, crush, or puncture the battery pack.
B Electrostatic Discharge Preventing Electrostatic Damage A discharge of static electricity from a finger or other conductor may damage system boards or other static-sensitive devices. This type of damage may reduce the life expectancy of the device. To prevent electrostatic damage when setting up the system or handling parts: • Avoid hand contact by transporting and storing products in static-safe containers.
Electrostatic Discharge Grounding Methods to Prevent Electrostatic Damage There are several methods for grounding. Use one or more of the following methods when handling or installing electrostatic-sensitive parts: • Use a wrist strap connected by a ground cord to a grounded workstation or computer chassis. Wrist straps are flexible straps with a minimum of 1 megohm ± 10 percent resistance in the ground cords. To provide proper ground, wear the strap snug against the skin.
