System Management Software
Embedded management software includes a web-browser interface and the
command-line interface described below.
HP StorageWorks MSA2000 Family Storage
Management Utility (SMU)
SMU is the primary interface for configuring and managing the system. A web
server resides in each controller module. SMU enables you to manage the system
from a web browser that is properly configured and that can access a controller
module through an Ethernet connection.
Information about using SMU is in its online help and in the reference guide.
Command-Line Interface (CLI)
The embedded CLI enables you to configure and manage the system using
individual commands or command scripts through an out-of-band RS-232 or
Ethernet connection.
Information about using the CLI is in the CLI reference guide.

Table 1-5 Controller LEDs (Back) (Continued)

Chapter 1 System Components 19
Controller
module
Cache status Green Blink A Compact Flash flush or cache self-refresh
is in progress. Indicates cache activity.
• If the LED is blinking evenly, a cache
flush is in progress. When a controller
module loses power and write cache is
dirty (contains data that has not been
written to disk), the super-capacitor pack
provides backup power to flush (copy)
data from write cache to Compact Flash
memory. When cache flush is complete,
the cache transitions into self-refresh
mode.
• If the LED is blinking slowly, a cache
flush is in progress. In self-refresh mode,
if primary power is restored before the
backup power is depleted (3
–30 minutes,
depending on various factors), the system
boots, finds data preserved in cache, and
writes it to disk. This means the system
can be operational within 30 seconds, and
before the typical host I/O timeout of 60
seconds at which point system failure
would cause host-application failure. If
primary power is restored after the backup
power is depleted, the system boots and
restores data to cache from Compact
Flash, which can take about 90 seconds.
Note: The cache flush and self-refresh
mechanism is an important data protection
feature; essentially four copies of user data
are preserved: one in each controller’s cache
and one in each controller’s Compact Flash.

Host activity Green Off The host ports have no I/O activity.
Blink At least one host port has I/O activity.

Safety Precautions
For your protection, observe the following safety precautions when setting up your
equipment:
■ Install the system in accordance with the local safety codes and regulations at the
facility site. Follow all cautions and instructions marked on the equipment.
■ Ensure that the voltage and frequency of your power source match the voltage
and frequency inscribed on the equipment’s electrical rating label.
■ Never push objects of any kind through openings in the equipment. Dangerous
voltages may be present. Conductive foreign objects could produce a short circuit
that could cause fire, electric shock, or damage to your equipment.
Note – Do not make mechanical or electrical modifications to the product. The
vendor is not responsible for the safety or regulatory compliance of a modified
product.
Caution – Two people are needed to lift and move the enclosure. Use care to avoid
injury. An enclosure with all drives installed can weigh 65 pounds (29.5 kilograms).
Caution – Electrostatic discharge can damage sensitive components. Be sure you
are properly grounded before touching a static-sensitive component or assembly.

Installing Enclosures Into a Rack
This section describes how to install the enclosures into a standard 19-inch rack
cabinet with a 28 to 36-inch (71.12 to 91.44-cm) depth.
Tip – To help you correctly identify the screws, keep all hardware items in plastic
bags until you are ready to use them.
Preparing the Rack
Before installing enclosures in a rack cabinet, ensure the rack is installed according
to its installation instructions and that the installation complies with local safety
codes.
1. Stabilize the rack as described in its documentation.
2. If the rack has casters, make sure the casters are locked to prevent the rack from
rolling.
3. Remove or open the top front panel and the vented back panel.
Assembling and Installing the Rackmount Bracket
Kit
Note – If the rackmount bracket kit you are installing includes assembly
instructions, use them in place of the instructions in this guide.

Use the following procedure and refer to Figure 2-1 to install each enclosure into
the rack.
Note – If the rackmount bracket kit you are installing includes assembly
instructions, use them in place of the instructions in this guide.
When positioning an enclosure in the rack, do not block the air vents at the front or
back of the enclosure.
Caution – If you only have one person to perform the installation, remove the
power and cooling modules and drive modules from an enclosure before
installation, and use the optional nylon front support brackets. If possible, position
the enclosure on top of another device or shelf in the rack to hold the enclosure as
you attach the front brackets.
1. Considering your system configuration and weight distribution in the rack,
determine where you will install each enclosure in the rack.
2. Confirm that you have cables of adequate length to connect to hosts and to power
outlets.
3. (Square-cut European-style racks only) Insert the cage nuts in the corresponding
holes on the front and rear of the rack.
4. (Optional-one person installation) Screw the front support nylon brackets into
position on the rack face using #10-32 x 5/8 screws (two per bracket).
These brackets enable one person to easily position and support the front of the
enclosure in the rack during installation.
5. Attach the side brackets to each side of the enclosure using #8-32 x 3/16 flathead
screws (four to eight on each side). The right and left side brackets are identical.
Note – To allow adjustment of the brackets, do not tighten the screws completely
until the enclosure is mounted in the rack.
a. Use the alignment marks (Figure 2-2) stamped into the side brackets to position
the brackets and screws. The alignment marks show depth in inches.
Determine the depth you require and align the rear-most alignment mark on the
side bracket with the rear-most threaded holes on the enclosure. Make sure that
the alignment mark corresponding to the depth you want lines up with both the
top and bottom holes.
