Rack Stability
WARNING: To reduce the risk of personal injury or damage to the equipment,
be sure that:
• The leveling jacks are extended to the floor.
• The full weight of the rack rests on the leveling jacks.
• The stabilizing feet are attached to the rack if it is a single-rack installation.
• The racks are coupled together in multiple-rack installations.
• Only one component is extended at a time. A rack may become unstable if
more than one component is extended for any reason.

System and Components
System
Figure 1-1: System, front view
Item Description
1 Disk drive or drive blank in bay 1 (shipped with drive
blanks)
2 Thumbscrews
3 System status LEDs
4 Disk drive or drive blank in bay 14
System and Components
1-2 HP StorageWorks Modular Smart Array 30 User Guide
Figure 1-2: System, rear view
Item Description
1 Environmental Monitoring Unit (EMU)
2 Power supply units
3 I/O module (single-port or dual-port)
4 Blowers
Each system has either one or two internal SCSI buses, depending on the I/O module
installed. Each bus supports the Ultra320, Ultra3, and Ultra2 protocols.
IMPORTANT: The system does not support single-ended (SE) drives. Installing an SE drive
creates an error condition.
The system fault bus is supported by the HP StorageWorks HS series of array
controllers. Thus the controller, in conjunction with the EMU, can monitor the status
of the system components (primarily the power supply units and blowers) and report
any error conditions by causing the component and system LEDs to be illuminated
appropriately. Additionally, the controller can detect when a disk drive has been
removed or installed.
System and Components
HP StorageWorks Modular Smart Array 30 User Guide 1-3
Ultra320 I/O Module
Figure 1-3: Ultra320 I/O modules
Item Description
1 Release latch
2 SCSI bus A connector, dual-port module
3 Status LEDs, with Ultra320 designator
4 SCSI bus B connector, dual-port module
5 SCSI bus A connector, single-port module
An I/O module supports up to 14 drives. With a dual-port module, these drives must
be shared between the two ports, so up to seven devices can be connected to each bus
in this case. Each bus requires its own host controller.
The I/O module has an internal sensor that provides protection from power surges. If
the current is too high, power to the module is discontinued. The module is then
disabled until the sensor detects that the current has returned to normal.
NOTE: The system must have both an Ultra320 I/O Module and an Ultra320 EMU for data
transfer rates to achieve Ultra320 speeds. The firmware on the hard drives must be upgraded
to ensure that the drives can also operate at Ultra320 speed.

Environmental Monitoring Unit
Figure 1-4: Environmental Monitoring Unit
Item Description
1 EMU status LED
2 (This socket not used in Modular Smart Array 30
systems)
Note: The purple handle indicates that the EMU is
hot-pluggable when used with an HP StorageWorks HS-type
controller.
The EMU performs the following functions:
• Assigns device SCSI addresses, in conjunction with the I/O module
• Monitors various temperatures relevant to optimum system operation:
— If the internal system temperature reaches 45°C (113°F), the EMU causes the
amber System Fault LED to become illuminated.
— If the ambient (room) temperature reaches 50°C (122°F) and Insight
Manager is running on the system, the EMU sends a signal to this utility to
indicate an alarm condition.
System and Components
HP StorageWorks Modular Smart Array 30 User Guide 1-5
— If the internal temperature of a power supply unit exceeds 85°C (185°F), the
power supply unit automatically shuts down.
• Monitors and reports the status of the power supply units, blowers, and system
(when the SCSI adapter or RAID controller supports this function):
— If the controller detects a device fault, it can send a signal to the EMU to
blink the specific device status LED rapidly.
— If the user requests identification of a device, the controller can cause the
EMU to blink the status LED of the specific device slowly.
NOTE: The system must have both an Ultra320 I/O Module and an Ultra320 EMU for data
transfer rates to achieve Ultra320 speeds. The firmware on the hard drives must be upgraded
to ensure that the drives can also operate at Ultra320 speed.
