Safety Precautions
When installing the HP Rack Storage/12, always keep the following safety and
environmental issues in mind, especially if you install the NetServer in a non-HP
Rack en vi ronm ent:
Maximum Recommended Ambient Temperature. The maximum
recommended ambient temperature is 35°C (95°F).
Elevated Operating Ambient Temperature. The ambient operating
temperature wit h a closed or mul ti-unit rack assembly ma y exceed t he room's
ambient temperature. Make sure that the temperature within the rack itself does
not ex ceed 3 5°C (95°F).
Reduced Air Flow. As you mount equipment in the rack, make sure that you
allow enough air flow for safe operation of the equipment.
Mechanical Loading. Uneven mechanical loading within the rack can cause
hazardous conditions. Plan the placement of equipment in the rack to make sure
that this problem does not occur.
Circuit Overloading. Make sure that the total configuration of equipment in the
rack does not overload the supply circuit. To this end, check the nameplate
ratings on all equipment. Consider the effect of circuit overloading on
overcurrent protection and supply wiring.
Reliable Grounding. Maintain reliable grounding of rack mounted equipment.
Give particular attention to supply connections that are not direct connections to
the branch circuit: the use of power strips, for example.

1HP Rack Storage/12 Overview
The HP Rack Storage/12 provides mass storage for use in an HP NetServer rack
mounted configuration. The HP Rack Storage/12 is compatible with the SCSI
(Small Computer System Interface) industry standard.
The embedded SCSI adapters in HP NetServers, and accessory SCSI adapters,
connect the host system and the HP Rack Storage/12. Adapters are available from
Hewlett-Packard (check with your HP Reseller). The HP NetServer adapters
include software that supports a variety of operating systems.
One or two RS/12 SCSI Card s connect the HP Rack S t orage/ 12 to the host
system.
The HP Rack Storage/12 System can be configured in one of three operating
environments: simplex, duplex, or cluster. The simplex configuration accesses up
to 12 addressed hard drives. The cluster configuration accesses up to 12
addressed hard drives from two host systems. The duplex configuration accesses
two banks of up to six hard drives each. The duplex configuration is useful for
either a small number of drives per channel or mirrored configurations. The hard
drives are available in a variety of capacities to meet your mass storage needs.
Front View

Status LEDs
The three Status LEDs indicate the current operating status of the HP Rack
Storage/12.
Bezel
The bezel covers the chassis, the support rails, and the thumbscrews securing the
chassis to the support rails. The bezel clips on to the chassis and can be installed
and removed without tools.
Drive Cage
The drive cage supports the installation of 8 half-height hard drives, 12
low-profile hard drives or a combination of half-height and low profile hard
drives. Drive spacers are used between half-height and low-profile hard drives.
Filler panels in unused drive slots are mandatory to maintain proper drive
cooling.
Configurations
Internal chassis braces divide the drive cage into four sections. Each section can
support the following hard drive configurations (see Figure 1-1):
• Three low-profile hard drives
• Two half-height hard drives
• One low-profile drive, one half-height drive and one drive spacer
SCSI Channe ls
Two internal SCSI channels connect the hard drives to the RS/12 SCSI card.
Hard drives installed in the left-half of the drive cage are connected to Channel 1.
The hard drives installed in the right-half of the drive cage are connected to
Channel 2 (see Figure 1-2).

Hot-Swap Hard Drives
For the latest list of HP-tested hard drive products, refer to the "Tested Products
List" Help topic on the HP NetServer Navigator CD-ROM or the Internet Web
page:
http://www.hp.com/netserver
NOTEDo not use hard drives that are not specifically certified by
Hewlett-Packard for use in the HP Rack Storage/12.
The hard drives are multimode disk drives, which allow the integration of the
differential drivers and receivers into SCSI drive control lers. The hard dr ive
technology provides increased signal quality, and ensures the same data integrity
as the previous high voltage differential designs at a reduced cost.
The HP Rack Storage/12 hot-swap hard drives come in two heights: the 1-inch
low-profile drive and th e 1.6-inch half-heigh t drive.
5
Page 12
Chapter 1HP Rack Storage/12 Overview
Status LED s
Each hard drive has two status indicators located in the lower left corner of the
front cover. The status indicators are drive activity and drive power. The
indicators are light pipes transmitting the output of two LEDs mounted on the
back-plane of t he dr ive cage.
Filler Panels
Filler panels are installed in unused hard drive slots in the drive cage. The 1-inch
filler panels must be inserted to ensure that drive cage has the proper air flow and
prevent excessive EMI (electromagnetic radiation). Remove the filler panel when
you install a new hard drive.
CAUTIONDo not remove the filler panels except to install a new hard
dri ve. Open s lots in th e d rive cag e can affect airfl ow and
cause thermal damage and excessive EMI.
Drive Spacers
Drive spaces are required when half-height and low-profile hard drives are
installed in the drive cage. The 0.5-inch drive spacer fills the space between
adjacent drives or between a drive and a filler panel. Drive spacers can be
mounted on low-profile drives, half-height drives and filler panels. Figure 1-1
shows the use of the drive spacer between half-height and low-profile hard
drives.
CAUTIONDo not remove the drive spacers except to install a new hard
dri ve. Open s lots in th e d rive cag e can affect airfl ow and
cause thermal damage and excessive EMI.

Chapter 1HP Rack Storage/12 Overview
Power Supplies
Two hot-swap power supplies are installed in the HP Rack Storage/12. Each
power supply includes an attached fan module. Power supply operation is
controlled by the power switch on the rear panel of the HP Rack Storage/12.
NOTE5 VDC standby power is supplied to the HP Rack Storage/12
even when the power switch is set OFF. T o r em ove standby
power, disconnect both power supplies from their AC sources.
The power supply provides DC power to HP Rack Storage/12 components.
Standby power and fan power are supplied through separ at e outputs. Th e power
supply adjusts to the AC power source voltage and frequency through
auto-ranging.
The power load is shared by both power supplies. If a power supply fails, the
remaining power supply provides DC power to HP Rack Storage/12 components.
CAUTIONDo not operate the HP Rack Storage/12 with a open power
supply slot. The chassis can overheat and damage
components.
NOTEReplace a failed power supply as soon as possible. The HP
Rack Storage/12 should not be operated for extended time
periods with only one operating power supply.
The power supply is protected from over-temperature conditions. When this
condition occurs, the power supply is shut down. The power supply will not
operate until the condition is removed and the AC power is cycled.
Fan Module
The variable speed fan module provides cooling airflow inside the HP Rack
Storage/12 chassis. Fan speed is regulated by the Management Board by
monitoring temperature sensors inside the chassis.
DC power is supplied to each fan by a redundant connection to both power
supplies. The fan continues to operate even if the attached power supply fails.

Chapter 1HP Rack Storage/12 Overview
RS/12 SCSI Card
The hot-swap RS/12 SCSI card connect s the disk storage of the HP Rack
Storage/12 to the host system. Data transfer rates of up to 40 Mb/sec are
supported. The HP Rack Storage/12 can be configured with one (simplex
configuration) or two (duplex or cluster configuration) RS/12 SCSI cards.
SAF-TE Chassis Management
Each RS/12 SCSI card includes a management processor that supports the
SAF-TE specification. The processor is accessible th rough SCSI I D 5.
SCSI Channe ls
The two SCSI channels are enabled by auto-configuration and configuration
switches on the Management Board.
When the HP Rack Storage/12 is powered on, Auto-configuration checks for how
many RS/12 SCSI cards are installed. Simplex configuration is enabled if one
RS/12 SCSI card is installed. Duplex configuration is enabled if two RS/12 SCSI
cards are installed. The cluster configuration is enabled by Switch 1 on the
Management Board. Descriptions of Simplex, Duplex, and cluster configurations
follow. See "Management Board" for a description of the configuration switches
later in this chapter.
Configuration S ettings
The configuration of the RS/12 SCSI card is stored in memory in the HP Rack
Storage/12. When a hot-swap RS/12 SCSI card is replaced, the configuration is
restored from memory. The configuration is only reset when the HP Rack

Chapter 5Removing and Installing HP Rack Storage/12 Components
Preparing the New Hard Dr ive
CAUTIONProtect the drive from static electricity by leaving it in its
anti-static bag until you are ready to install it. Before
handling the drive, touch any unpainted metal surface to
discharge static electricity. When you remove the drive from
the anti-static bag, handle it only by the frame.
Do not touch th e electr ical comp onent s . Place the drive on
the anti-static bag whenever you set it down.
Hard disk drives are very susceptible to mechanical shock and
can be damaged by a drop as short as one-quarter of an inch.
Take care when unpacking and handling the drive. If the
drop would crack an egg, it will damage the drive.
1. Remove the hard drive from its anti-static container and set it on an
anti-static mat.
Attachin g a Driv e Spacer
Drive spacers are attached to the right side of the hard drive with four tabs (see
Figure 5-1). The drive space can be attached to half-height drives, low-profile
drives, and filler panels.

6Troubleshooting
Checking for General Problems
• If the chassis status LED is flashing red, or flashing yellow, check for
failed components on the front and rear panel. Check status LEDs and
ind icators on each component.
• If the Management Board Temperature LED is flashing yellow, the
chassis is too hot. Check the following:
◊Both HP Rack Storage/12 fans are operating.
◊Rack cooling fans are operating.
◊Remove obstructions in the rack that could affect airflow to the HP
Rack Storage/12.
• Check that all cables and power cords are firmly plugged into their proper
receptacles.
• Check that all parts of the system are turned on and properly adjusted.
• If the system is plugged into a switched multiple-outlet box, make sure the
switch on the outlet box is turned on.
• Plug a different electrical device (such as a printer) into the power outlet,
and turn it on.
• Always exchange units suspected of malfunctioning with another unit you
know is operable.
No System Power
• If no LEDs are lit, both power supplies are either dead or disconnected.
• If one power supply LED is green, the system can operate properly.
• If one power supply Power LED is not lit, check the following:
◊You have properly seated the power supply in its connector.
47
Page 54
Chapter 6Troubleshooting
◊Ensure that all power cords are firmly plugged into the proper
receptacles.
• If the system is plugged into a switched, multiple-outlet box, make sure
the switch on the outlet box is turned to the on position.
• If the power supply still does not power up, it may be defective. Remove
and replace it with a di fferent power supply.
• Shut down the system and exchange the faulty unit with the other unit.
Restart the system and check both power supplies.
Hard Drives Not Responding
• If the OS Event Log displays device timeouts, one or more hard drives
cannot access the SCSI channel due to high system or disk activity.
Device timeouts may occur in a simplex configuration of 12 hard drives. If
timeouts occur frequently, the recommended solution is to add a second
RS/12 SCSI card and connect to the host through a duplex configuration.
• If the Drive Power Indication is not lit, check the following:
◊Check to make sure that the HP Rack Storage/12 is powered on and
the there is power to the unit.
◊Check that the hard drive is seated in the drive cage. Remove and
reinstall the hard drive. If the hard drive still does not spin up, replace
it with another hard drive.
• If the Drive Activity Indicator displays green for more than one minute,
the hard drive is either spinning up or has "hung." Check the drive status
through your RAID management application.
• If the Drive Activity Indicator is flashing yellow, the hard drive is
predicting a failure. Replace it with a new hard drive.
• If the Drive Activity Indicator is red, the hard drive has been marked
offline or has failed. Replace it with a new hard drive.
48

Chapter 6Troubleshooting
RS/12 SCSI Card Not Responding
• If the hard d rives con nected to the RS/ 1 2 SCSI ca rd cannot be accessed,
check data cable connections between the HP Rack Storage/12 and the
host system.
• If the Status LED is not lit, check that the board is properly seated in the
chassis.
• If the Status LED is yellow, verify that both installed RS/12 SCSI cards
support the sa m e SAF-TE processor revision.
• If the Status LED is red, the board is defective. Replace the board with a
new board.
Management Board Not Responding
• Check to make sure that the HP Rack Storage/12 is powered on and that
there is power to the unit.
• If the Temperature LED is not lit, remove the Management Board and
replace it with a new board.
• If the Temperature LED is flashing yellow, the chassis is too hot. Verify
that both fans are operating properly.
• If the status LED is flashing red, the chassis is too hot and auto-shutdown
is imminent. Verify that both fans are operating properly.
