1 Overview
The HP 9000 rp7420 server is a member of the HP business-critical computing platform family.
It is a mid-range, mid-volume server, positioned as an upgrade to the HP 9000 rp7410 server in
the PL-1X product line. The HP 9000 rp7420 server shares the same hardware as the HP 9000
rp7410 server with changes to the cell board, CPU modules, core I/O, and the PCI-X backplane.
The HP 9000 rp7420 server provides increased performance over its predecessor.
Introduction
The HP 9000 rp7420 server is a 10U, 8-socket symmetric multi-processing, rack-mounted server
that accommodates up to 64 GB of memory; PCI-X I/O, and internal peripherals, including disks
and DVD/tape.Its high availability features include N+1 hot-pluggable fans and power, redundant
power cords, and hot-pluggable PCI-X cards and internal disks. It currently uses dual core,
PA-RISC processors.

Introduction 17
Page 18
Figure 1-2 HP 9000 rp7420 server (without front bezel)
System Backplane
The system backplane is comprised of the system clock generation logic, the system reset
generation logic, DC-to-DC converters, power monitor logic, and two Local Bus Adapter (LBA)
link-to-PCI converter ASICs. It also includes connectors for attaching the cell boards, the PCI-X
backplane, Management Processor (MP) Core I/O MP/SCSI boards, SCSI cables, bulk power,
chassis fans, the front panel display, intrusion switches, and the system scan card. Unlike the
Superdome or rp8400 servers, there are no Crossbar Chips (XBC) on the system backplane. The
“crossbar-less” back-to-back Cell Controller (CC) connection increasesperformance and reduces
costs.
Only half of the MP Core I/O board set connects to the system backplane. The MP/SCSI boards
plug into the backplane, while the LAN/SCSI boards plug into the PCI-X backplane.
18 Overview
Page 19
Figure 1-3 System Backplane Block Diagram
System Backplane to PCI-X Backplane Connectivity
The PCI-X backplane uses two connectors for the System Bus Adapter (SBA) link bus and two
connectors for the high speed data signals and the manageability signals.
SBA link bus signals are routed through the system backplane to the CC on each corresponding
cell board.
The high speed data signals are routed from the SBA chips on the PCI-X backplane to the two
LBA PCI bus controllers on the system backplane.
Clocks and Reset
The system backplane contains reset and clock circuitry that propagates through the whole
system. The central clocks drive all major chip set clocks. Therefore, these circuits represent a
system-wide single point of failure.
I/O Subsystem
The cell board to the PCI-X board path runs from the CC to the SBA, from the SBA to the ropes,
from the ropes to the LBA, and from the LBA to the PCI slots seen in Figure 1-4. The CC on cell
board 0 and cell board 1 each communicate with individual SBAs over the SBA link. The SBA
link consists of both an inbound and an outbound link with an effective bandwidth of
approximately 1 GB/sec. The SBA converts the SBA link protocol into “ropes.” A rope is defined
as a high-speed, point-to-point data bus. The SBA can support up to 16 of these high-speed
bi-directional rope links for a total aggregate bandwidth of approximately 4 GB/sec. Each LBA
acts as a bus bridge, supporting either one or two ropes and capable of driving 33 Mhz or 66
Mhz for PCI cards. The LBAs can also drive at 66 Mhz or 133 Mhz for PCI-X cards.
Introduction 19
Page 20
Figure 1-4 PCI-X Board to Cell Board Block Diagram
NOTE: PCI-X slots 1 through 7 are dual rope slots, while slot 8 is a single rope slot.
The PCI-X backplane is the primary I/O interface for HP 9000 rp7420 servers. It provides sixteen
64-bit, hot-plug PCI/PCI-X slots. Fourteen of the slots have dual ropes connected to the LBA
chips. The remaining two slots have a single rope connected to each LBA chip. Each of the sixteen
slots are capable of 66 MHz/33 MHz PCI or 133 MHz/66 MHz PCI-X. All sixteen PCI slots are
keyed for 3.3-volt connectors (accepting both Universal and 3.3-V cards). The PCI-X backplane
does not provide any 5-volt slots for the I/O cards. For more details, see Table 1-1.
The PCI-X backplane is physically one board but behaves like two independent partitions. SBA
0 and its associated LBAs and eight PCI-X slots form one I/0 partition. SBA 1 and its associated
LBAs and eight PCI-X slots form the other I/0 partition. One I/O partition can be powered down
separate from the other I/O partition.

Cell Board
The cell board contains several hardware blocks connected by several data buses. The major
hardware blocks are the Central Processor Units (CPUs), the Cell Controller, the Memory
Controllers, and the Memory. Minor hardware blocks include Clock Distribution, Power
Distribution, Reset Circuit, and Platform Dependent Hardware (PDH) Riser BoardInterface. The
buses include two Front Side Buses (FBS0 and FBS1), a Memory (MID) bus, a Crossbar (XB) bus,
and an I/O bus. All these blocks come together at the CC chip.
Figure 1-6 Cell Board
The HP 9000 rp7420 server has a 48-V distributed power system and receives the 48-V power
from the system backplane board. The cell board contains DC-to-DC converters to generate the
required voltage rails. The DC-to-DC converters on the cell board do not provide N+1 redundancy.
Because of space limitations on the cell board, the PDH/PDHC circuitry resides on a riser board
that plugs into the cell board at a right angle. The cell board also includes clock circuits, test
circuits, and de-coupling capacitors.
Figure 1-7 shows a simplified view of the memory subsystem. It consists of two independent
access paths, each path having its own address bus, control bus, data bus, and DIMMs . In practice,
the CC runs the two paths 180 degrees out of phase with respect to each other to facilitate
pipelining in the CC. Address and control signals are fanned out through register ports to the
synchronous dynamic random access memory (SDRAM) on the DIMMs.
22 Overview
Page 23
Figure 1-7 Memory Subsystem
PDH Riser Board
The Platform Dependant Hardware Riser board is a daughter card for the cell board. It contains
a micro-processor memory interface microcircuit, processor-dependent hardware including the
processor-dependent code (PDC), flash memory, and a manageability microcontroller, called
the PlatformDependant Hardware Controller(PDHC) with associated circuitry. The PDH obtains
cell board configuration information from cell board signals and from the LPM on the cell.
The PDH riser board contains circuitry that the cell board requires to function and, therefore,
each cell board must have a PDH riser installed before it is added to a server.
Central Processor Units
The cell board can hold up to eight (four dual-core) CPUs and can be populated with CPUs in
increments of two CPUs. On a cell board, the processors must be the same type and speed. Two
CPUs is the minimum configuration allowed on the HP 9000 rp7420 server. There are two
Frontside Buses (FBS), one for sockets 0 and 1, and one for sockets 2 and 3. Each FBS must have
either a CPU or a terminator at the end of the bus or the board does not operate properly. There
cannot be a terminator board in socket 1 or socket 3 locations. For the CPU load order that must
be maintained when adding CPUs to the cell board, see Table 1-2. For the locations on the cell
board for installing CPUs, see Figure 1-8.

DIMMs
Custom designed by HP, each DIMM contains 36 x 4 SDRAM memory components similar to
PC-133 memory, but qualified to run at 125 MHz. They have a low-voltage TTL interface. The
CEC does not support traditional DRAMs.
The HP 9000 rp7420 server supports DIMMs with 256 MB, 512, MB, 1 GB, and 2 GB capacity.
Table 1-3shows each DIMM supported with its associated capacity, the resulting total system
capacity, and the memory component density.
DIMMs mustbe loaded in sets of two at specific locations. For best performance, HP recommends
loading sets of eight DIMMs.

Main Memory Performance
Latency to main memory is an important parameter in determining overall system performance.
With memory buses running at 125 MHz, the latency for a page hit is 8.5 cycles (68 ns), the latency
for a page closed is 11.5 cycles (92 ns), and the latency for a page miss is 14.5 cycles (116 ns).
Valid Memory Configurations
The HP 9000 rp7420 server is capable of supporting as little as 0.5 GB of main memory using two
256 MB DIMMs installed on a single cell board and as much as 128 GB by filling all 16 DIMM
slots on both cell boards with 4 GB DIMMs.
DIMMs must be loaded in sets of two at specified locations on the cell board. Two DIMMs are
called a rank; two ranks would be equivalent to four DIMMs, three ranks would be six DIMMs,
and so on. The DIMMs must be the same size in a rank. The DIMMs across all cells in a partition
should have identical memory loaded. Figure 1-9 shows the DIMM slot layout on the cell board.
For DIMM load order, see Table 1-4.
A quad seen in Figure 1-9 is a grouping of four DIMMs. Configurations with 8 or 16 DIMM slots
loaded are recommended. The DIMM sizes in a quad can be different but the DIMMs in a rank
must be the same size.

Cells and nPartitions
A cell board that has an I/O link to a bootable device and a console (usually supplied by an MP
core I/O card) is a potential boot cell. The cell that contains the boot console I/O path is the called
the root cell. Both cells are potential root cells. The primary or default root cell in a single nPartition
system is the bottom cell (cell 1).
An nPartition (also called a Protection Domain) is a cell or cells running the same operating
system and sharing processes and memory space among the components. Each nPartition must
have one root cell and can contain both cells. The HP 9000 rp7420 server has only two possible
nPartition configurations: single or dual. The additional cell that can be part of the nPartition
does not require I/O links or MP core I/O cards.
In the single nPartition case, if two cells are present, either cell can be the root cell, assuming
both cells have MP core I/O functionality present. If only one cell is present, that cell is the root
cell (and should be cell 1).
In the dual nPartition case (two cells required), each nPartition consists of one cell, and each cell
must be a root cell. The ability to interconnect two cells in one nPartition or isolate the cells in a
dual nPartition system provides system configuration flexibility. System partitioningis configured
by the system MP.
NOTE: Partition configuration information is available on the HP website at http://
docs.hp.com. For more detail, see the HP Systems Partition Guide: Administration for
nPartitions.
Internal Disk Devices for the HP 9000 rp7420 server
In an HP 9000 rp7420 server, the top internal disk drives connect to cell 1 through the core I/O
for cell 1. Both of the bottom disk drives connect to cell 0 through the core I/O for cell 0.
The CD/DVD/DAT drive connects to cell 1 through the core I/O card for cell 1.
26 Overview
Page 27
Figure 1-10 Internal Disks
MP/SCSI MP Core I/O Board
The HP 9000 rp7420 server accommodates two sets of MP Core I/O functionality. Each MP/SCSI
core I/O board set consists of a MP/SCSI board and a Procurium LAN/SCSI board. At least one
MP/SCSI board is required (independent of partitions). An additional MP/SCSI board can be
added as well (and is required in a dual partition system). Both MP/SCSI boards are oriented
vertically and plug into the system backplane. The MP/SCSI board incorporates a dual channel
Ultra160 SCSI controller.
Procurium LAN/SCSI Board
At least one Procurium LAN/SCSI board is required for the minimum system configuration; two
are required in a dual partition system. The Procurium board is a standard PCI form factor card
with PCI card edge connectors. The PCI-X backplane has one slot location reserved for the
required Procurium board and another that can accommodate either a Procurium board or any
other supported add-in PCI-X card. The Procurium board is hot-pluggable.
Mass Storage (Disk) Backplane
Internal mass storage connections (to disks) are routed on the mass storage backplane, having
connectors and termination circuitry. All disks are hot-pluggable. The HP 9000 rp7420 server
accommodates one internal, removable media device. Therefore, only one power connector for
a removable media device is required on the mass storage backplane. The mass storage backplane
incorporates a circuit that enables power to the internal removable media device to be
programmatically cycled.

Server Description
Dimensions
The dimensions of the HP 9000 rp7420 server are as follows:
• Width: 44.45 cm (17.5 inches), constrained by EIA standard 19 inch racks
• Depth: Defined by cable management constraints to fit into standard 36-inch deep racks
(Rittal/Compaq, Rosebowl I):
25.5 inches from front rack column to PCI connector surface
26.7 inches from front rack column to MP Core I/O connector surface
30 inches overall package dimension, including 2.7 inches protruding in front of the front
rack columns
• Height: 10U – 0.54 cm = 43.91 cm (17.287 inches). This is the appropriate height for a product
that consumes 10U of rack height while allowing adequate clearance between products
directly above and below this product. Fitting four server units per 2 m rack and upgrade
of current 10U height products in the future are the main height constraints.
System Chassis
The mass storage section located in the front enables access to removable mass storage devices
without removal of the bezel (not shown). This is especially helpful when the system is mounted
in the lowest position in a rack. The mass storage bay accommodates one 5.25-inch removable
media device and up to four 3.5-inch hard drives. The front panel display board, containing
LEDs and the system power switch, is located directly above the 5.25-inch removable media bay.
Below the mass storage section and behind a removable bezel are two PCI DC-to-DC power
converters.
The BPS section is partitioned by a sealed metallic enclosure located in the bottom of the package.
This enclosure houses the N+1 fully redundant BPS.
28 Overview
Page 29
Figure 1-11 Right-Front View of HP 9000 rp7420 server
The PCI-X card section, located toward the rear, is accessed by removing the top cover.
The PCI OLR fan modules are located in front of the PCI-X cards. These six 9.2-cm fans are housed
in plastic carriers. They are configured in two rows of three fans.
The MP/SCSI MP core I/O boards are positioned vertically at the rear of the chassis.
The PCI-X card bulkhead connectors are located in the top rear portion of the chassis.
Four OLR system fan modules, externally attached to the chassis, are 15-cm (6.5-inch) fans. Two
fans are mounted on the front surface of the chassis and two are mounted on the rear surface.
The two hot-pluggable N+1 redundant BPS provide a wide input voltage range. They are installed
in the front of the chassis, directly under the front fans.
A cable harness that connects from the rear of the BPSs to the system backplane provides DC
power distribution.
Access the system backplane by removing the left side cover. The system backplane inserts by
a guide/insertion mechanism using a single large jack screw assembly.
SCSI ribbon-cable assemblies route from the mass storage area to the backside of the system
backplane and to the Procurium PCI MP core I/O card.
Access the cell boards from the right side of the chassis behind the removable side cover.

2 Unpacking the Server
HP shipping containers are designed to protect their contents under normal shipping conditions.
After the equipment arrives, carefully inspect each carton for signs of shipping damage. A tilt
indicator is installed on each carton shipped. The beads in the indicator roll to the upper position
if the container was tilted to an angle that could cause equipment damage. The tilt indicator itself
has two windows, and each window, under normal conditions, shows four beads present. If a
carton was mishandled or accidentally dropped, the tilt indicator indicates missing beads. If
damage is found, document the damage with photographs and contact the transport carrier
immediately.
Examine the server cabinet for visible shipping damage. After unpacking the cabinet, check for
damage that might have been obscured by the shipping container. If damage is found after visual
inspection, documentthe damagewith photographs and contact the transport carrier immediately.
If the equipment has any damage, a damage claim form must be obtained by the customer from
the shipping representative. The customer should complete the form and return it to the shipping
representative.
NOTE: The server might come already racked or ready for rack installation.

Card DescriptionPart Number
Installing PCI I/O Cards
HP 9000 rp7420 servers implement manual release latch (MRL) hardware for use in online add
or replacement (OLAR) operations. If an MRL is left open while the server is booting, HP-UX
can incorrectly cache PCI slot power status causing OLAR operations to fail. To prevent this
situation, ensure all the MRLs are closed before booting the server.
If OLAR reports that a slot is present and powered off, but no OLAR operations to turn power
on to that slot have succeeded even after the MRL is closed, the MRL may have been left open
during boot. To clear this condition, close the MRL for the PCI slot then power off the PCI slot
using the rad -o command. This will allow future OLAR operations to succeed on this PCI
slot.

IMPORTANT: PCI I/O card installation procedures should be downloaded from the HP website
at http://docs.hp.com. Background information and procedures for adding a new PCI I/O
card using online addition are found in the Interface Card OL* Support Guide.
Prerequisites for Adding a PCI I/O Card Using the Attention Button
The prerequisites for this procedure are:
• Drivers for the card have already been installed.
• There are no drivers associated with the slot.
• The green power LED is steady Off.
Should the empty slot be in the On state, use the olrad command or the pdweb tool to
power off the slot.
• The yellow attention LED is steady Off or is blinking (if a user has requested the slot location).
• For details on card installation, see the host bus adapter (HBA) documentation.
PCI-X Card Cage Assembly I/O Cards 47
Page 48
• To determine the status of all the PCI I/O slots, run the olrad -q command.
• Obtain a copy of the interface card guide for instructions on preparing the operating system
for the online addition of the PCI I/O card before attempting to insert a PCI I/O card into
the PCI-X card cage assembly backplane slot.
CAUTION: Observe all ESD safety precautions before attempting this procedure. Failure to
follow ESD safety precautions could result in damage to the server.
This procedure describes how to perform an online addition of a PCI card using the attention
button for cards whose drivers support OLAR. The attention button is also referred to as the
doorbell.
To add a PCI I/O card, follow these steps:
1. Remove the top cover.
2. Remove the PCI bulkhead filler panel.
3. Flip the PCI MRL for the card slot to the open position. See Figure 3-8.
4. Install the new PCI card in the slot.
NOTE: Apply a slow, firm pressure to the card to properly seat it into the backplane.
5. Flip the PCI MRL for the card slot to the closed position.
CAUTION: Working out of sequence or not completing the actions within each step could
cause the system to crash.
Do not press the attention button until the latch is locked.
6. Press the attention button.
The green power LED starts to blink.
Figure 3-8 PCI I/O Slot Details
7. Wait for the green power LED to stop blinking and remain solid green.
48 Installing Accessories
Page 49
8. Check for errors in the hotplugd daemon log file (default: /var/adm/hotplugd.log).
The critical resource analysis (CRA) performed while doing an attention button initiated
add action is very restrictive and the action will not complete—it will fail—to protect critical
resources from being impacted. For finer control over CRA actions use pdweb or the olrad
command. See the Interface Card OL* Support Guide located on the Web at http://
docs.hp.com for details.
9. Replace the top cover.
10. Connect the cables to the installed PCI card.

4 Cabling and Powering the Server
After you have unpacked the server and moved into position, you must be connect it to an AC
power source. Check the AC power for the proper voltage before you power the system on. This
chapter describes these activities.
AC Input Power
The server has the following line-cord configurations:
• All four line cords (preferred configuration)
• Cords A0 and A1 only
• Cords B0 and B1 only
• Cords A0 and B0 only
• Cords A1 and B1 only
A single-line-cord configuration is not allowed.
Figure 4-1 Power Cord Configuration
The power cord configuration is passed to the operating system using the pwrgrd (Power Grid)
command. Each of the five selections in the pwrgrd command matches one of the configurations.
The appropriate option should be selected for the actual line cord configuration. With the correct
configuration selected, the LEDs should be green. When the pwrgrd command is invoked, the
following menu displays:
prompt> pwrgrd
Power grid configuration preference.
1. Grid A only (Cords A0,B0 required)
2. Grid B only (Cords A1,B1 required)
3. Grids A & B (Cords A0,A1,B0,B1 required)
4. Cords A0 & B0 only5. Cords A1 & B1 only
Select Option:
If two separate power sources are available, the two power supplies can be plugged into the
separate power sources, increasing system reliability should one power source fail.
AC Input Power 51
Page 52
Figure 4-2 Power Source versus Power Distribution
WARNING! Voltage is present at various locations within the server whenever a power source
is connected. This voltage is present even when the main power switch is in the OFF position.
To completely remove power, all power cords must be removed from the server. Failure to
observe this warning can result in personal injury or damage to equipment.
NOTE: System firmware prevents boot when a single power cord configuration is detected.
Checking the Voltage
This section provides voltage check information for use on the customer site. The emphasis
focuses on measuring the voltages at the power cord plug end specified as an IEC 320 C19 type
plug. This end plugs directly into the back of the HP 9000 rp7420 server chassis.
NOTE: Perform these procedures for each power cord to be plugged directly into the back of
the HP 9000 rp7420 server. If you do not get the expected results from this voltage check, see
“Checking the Voltage (Additional Procedure)” (page 54).
Verifying the Voltage Range of the Receptacle
This measures the voltage between L1 and L2, L1 to ground, and L2 to ground. Three separate
measurements areperformed duringthis procedure.For voltage reference points when performing
the measurements, see Figure 4-3.
52 Cabling and Powering the Server
Page 53
Figure 4-3 Voltage Reference Points for IEC 320 C19 Plug
IMPORTANT: Perform the following measurements for every power cord that plugs into the
HP 9000 rp7420 server.
1. Measure the voltage between L1 and L2. This is considered to be a phase-to-phase
measurement inNorth America. In Europe and certain parts of Asia-Pacific, this measurement
is referred to as a phase-to-neutral measurement. The expected voltage measured should
be between 200–240 VAC regardless of the geographic region.
2. Measure the voltage between L1 and ground. In North America, verify this voltage is between
100–120 VAC. In Europe and certain parts of Asia-Pacific, verify this voltage is between
200–240 VAC.
3. Measure the voltage between L2 and ground. In North America, verify this voltage is between
100–120 VAC. In Europe and certain parts of Asia-Pacific, verify this voltage is 0 (zero) VAC.
Table 4-1 provides single phase voltage measurement examples dependent on the geographic
region where these measurements are taken.

Verifying the Safety Ground
This measures the voltage level between B0 and A0. The measurement is taken between ground
pins of the two power cords. For ground reference points when performing this measurement,
see Figure 4-4.
Checking the Voltage 53
Page 54
Figure 4-4 Safety Ground Reference Check
To measure the voltage, follow these steps:
1. Measure the voltage between B0 and A0. Take the AC voltage down to the lowest scale on
the volt meter.
2. Insert one probe into the ground pin for B0.
3. Insert the other probe into the ground pin for A0.
4. Verify that the measurement is between 0–5 V AC. If the measurement is 5 V or greater,
escalate the situation. Do not attempt to plug the power cords into the HP 9000 rp7420 server.
Checking the Voltage (Additional Procedure)
The voltage check ensures that all phases (and neutral, for international systems) are connected
correctly to the cabinet and that the AC input voltage is within limits.
This procedure must be performed if the previous voltage check procedure did not yield the
expected results as previously outlined.
NOTE: If a UPS is used, see the applicable UPS documentation for information to connect the
server and to check the UPS output voltage. UPS user manual documentation is shipped with
the UPS. Documentation can also be found at http://www.hp.com/racksolutions.
1. Verify that site power is off.
2. Open the site circuit breakers.
3. Verify that the receptacle ground connector is connected to ground. For connector details,
see Figure 4-5.
4. Set the site power circuit breaker to On.
54 Cabling and Powering the Server
Page 55
Figure 4-5 Wall Receptacle Pinouts
WARNING! There is a risk of shock hazard while testing primary power. Use properly
insulated probes.
5. Verify that the voltage between receptacle pins x and y is between 200 and 240 V AC.
6. Set the site power circuit breaker to Off.
7. Ensure that power is removed from the server.
8. Route and connect the server power connector to the site power receptacle.
• For locking type receptacles, line up the key on the plug with the groove in the receptacle.
• Push the plug into the receptacle and rotate to lock the connector in place.
WARNING! Do not set site AC circuit breakers serving the processor cabinets to On before
verifying that the cabinet has been wired into the site AC power supply correctly. Failure
to do so might result in injury to personnel or damage to equipment when AC power is
applied to the cabinet.
9. Set the site power circuit breaker to On.
10. Set the server power to On.
11. Check that the indicator light on each power supply is on.
MP Core I/O Connections
Each HP 9000 rp7420 server can have up to two MP core I/O board sets installed. Which allows
two partitions to operate, or MP core I/O redundancy in a single partition configuration. Each
MP core I/O board set consists of two boards: the MP/SCSI board and the LAN/SCSI board. The
MP/SCSI board is oriented vertically and accessed from the back of the server. The LAN/SCSI is
accessed from the PCI/PCI-X expansion card bay. Only the primary MP core I/O board set
(MP/SCSI slot 1 and LAN/SCSI slot 8, chassis 1) is required for a single partition implementation.
The secondaryMP/SCSI board is not necessary for full operation. However, without the secondary
MP/SCSI board, only two internal disks can be accessed.
MP/SCSI Connections
The MP/SCSI board is required to update firmware, access the console, turn partition power on
or off, access all but two of the internal peripherals, and use other features of the server.
Connections to the MP/SCSI board include the following:
MP Core I/O Connections 55
Page 56
• DB25 connector, by way of the M cable
This RS-232 connector provides connections for a local console, external modem, and a UPS.
The server end of the M cable terminates in a DB25 connector. The opposite side of the cable
terminates in three DB9 connectors labeled CONSOLE, UPS, and REMOTE.
• 10/100 Base-T LAN RJ45 connector (for LAN and web console access).
This LAN uses standby power and is still active if the front panel power switch is off and
AC is present.
• Internal LVD Ultra 160 SCSI channel for connections to internal mass storage
• Internal SE Ultra SCSI channel for connection to an internal removable media device.
LAN/SCSI Connections
The LAN/SCSI board is a PCI form factor card that provides the basic external I/O connectivity
for the system.
Connections to the LAN/SCSI board include the following:
• PCI-X to PCI-X bridge for multi-device compatibility.
• Internal LVD Ultra 160 SCSI channel for connections to internal mass storage.
• External LVD Ultra 160 SCSI channel connected to a 68-pin VHDCI connector.
• 10/100/1000 Base-T LAN RJ45 connector.
The primary LAN interface is located on the LAN/SCSI board installed in the right-most slot
when viewing the system from the back.
Management Processor Access
NOTE: To access the MP for the initial installation, you must first connect the M cable to the
DB25 connector located on the primary MP/SCSI board. The primary MP/SCSI board is located
in the lower MP/SCSI board slot.
Setting Up the Customer Engineer Tool (PC)
The Customer Engineer (CE) Tool is usually a laptop. It enables communication with the MP in
the HP 9000 rp7420 server. The MP monitors the activity of either a one partition or a
multiple-partition configuration.
During installation, communicating with the MP enables such tasks as:
• Verifying that the components are present and installed correctly
• Setting LAN IP addresses
• Shutting off cell board power
Communication with the MP is established by connecting the CE Tool to the local RS-232 port
on the MP Core I/O card.
Setting CE Tool Parameters
After powering on the CE Tool, ensure the communications settings are as follows:
• 8/none (parity)
• 9600 baud
• na (Receive)
• na (Transmit)
If the CE Tool is a laptop using Reflection, ensure communications settings are in place by
following these steps:
1. From the Reflection Main screen, pull down the Connection menu and select Connection
Setup.
56 Cabling and Powering the Server
Page 57
2. Select Serial Port.
3. Select Com1.
4. Check the settings and change, if required.

6. Pull down the Setup menu and select Terminal (under the Emulation tab).
7. Select terminal type VT100.
8. Click Apply.
This option is not highlighted if the terminal type you want is already selected.
9. Click OK.
Connecting the CE Tool to the Local RS-232 Port on the MP
This connection allows direct communications with the MP. Only one window can be created
on the CE Tool to monitor the MP. When enabled, it provides direct access to the MP and any
partition.
To connect the CE Tool to the Local RS-232 port on the MP, follow these steps:
1. Connect one end of a null modem cable (9-pin to 9-pin) (Part Number 5182-4794) to the M
cable connector labeled CONSOLE.
2. Connect the other end of the RS-232 cable to the CE Tool.
Standby Power and Logging In to the MP
After connecting the serial device, it is possible to log in to the Management Processor (MP).
Housekeeping power (also known as standby power) is generated as soon as AC power is applied
to the server. Because the MP uses standby power, it is possible to log in to the MP even when
the power switch is in the OFF position. The power switch is a DC power switch that controls
+48 V DC.
Before powering up the HP 9000 rp7420 server for the first time, follow these steps:
1. Verify that the AC voltage at the input source is within specifications for each server being
installed.
2. If not already done so, power on the serial display device.
The preferred tool is the CE Tool running Reflection.
To power up the MP, set up a communications link, and log in to the MP, follow these steps:
1. Connect the server to AC power.
On the front of the HP 9000 rp7420 server, a solid green Standby Power LED, a solid green
MP Present LED, and a flashing amber Attention LED illuminate after about 30 seconds.
Figure 4-6 Front Panel Display
2. Check the bulk power supply LED for each BPS.
When on, the breakers distribute power to the BPSs. AC power is present at the BPSs:
MP Core I/O Connections 57

what is in the Cells column with the cells physically located inside the cabinet.
Figure 4-12 shows that cells are installed in slots 0 and 1. In the cabinet, cells should be
physically located in slots 0 and 1.
Booting the HP 9000 rp7420 Server
After powering on the MP, +3.3 V housekeeping power, and verifying that the MP detects the
presence of the cell boards, power on the server.
If using a LAN crossover cable with the laptop, review server activity for each partition configured,
while the server powers on and boots. Windows can be opened for the complex and for each
partition. HP recommends that at least two windows be opened:
• A window showing all activity in the complex. Following the installation procedure in this
manual causes a window to be open at startup.
To display activity for the complex, follow these steps:
1. Open a separate Reflection window and connect to the MP.
2. From the MP Main Menu, select the VFP command with the s option.
• A window showing activity for a single partition.
To display activity for each partition as it powers up, follow these steps:
1. Open a separate Reflection window and connect to the MP.
62 Cabling and Powering the Server
Page 63
2. Select the VFP command and select the desired partition to view.
There should be no activity on the screen at this point in the installation process.
NOTE: More than one window cannot be opened using a serial display device.
To power on the server, follow these steps:
1. Switch the power switch at the front of the server to On. The following occurs:
• Power is applied to the server.
• PDC starts to run on each cell.
• The cell self test executes.
• Hardware initializes for the server.

4. Main Menu: Enter command or Menu> bo pri
5. The following prompt displays:
Do you wish to stop at the ISL prompt prior to booting (y/n)?
Enter n.
NOTE: If the partition fails to boot or if the server was shipped without Instant Ignition, booting
from a DVD that contains the operating system and other necessary software might be required.
Adding Processors With Instant Capacity On Demand
The Instant Capacity On Demand (iCOD) program provides access to additional CPU resources
beyond the amount that was purchased for the server. This provides the ability to activate
additional CPU power for unexpected growth and unexpected spikes in workloads. Internally,
iCOD systems physically have more CPUs, called iCOD CPUs, than the number of CPUs actually
purchased. TheseiCOD CPUsreside in the purchased system, but they belong to HP and therefore
are HP assets. A nominal “Right-To-Access Fee” is paid to HP for each iCOD processor in the
system. At any time, any number of iCOD CPUs can be “activated.” Activating an iCOD CPU
automatically and instantaneously transforms the iCOD CPU into an instantly ordered and
fulfilled CPU upgrade that requires payment. After the iCOD CPU is activated and paid for, it
is no longer an iCOD CPU, but is now an ordered and delivered CPU upgrade for the system.
The most current information on installing, configuring, and troubleshooting iCOD can be found
at http://docs.hp.com.
NOTE: You need to be aware of the iCOD email requirements. For further details, see http://
docs.hp.com.

5 Troubleshooting
This chapter contains information about the various status LEDs on the HP 9000 rp7420 server
and other troubleshooting information.
Common Installation Problems
The following sections contain general procedures to help you locate installation problems.
CAUTION: Replace the top cover before operating the server, even for a short time. Otherwise,
overheating can damage chips, boards, and mass storage devices. However, you can safely
remove the PCI access panel while the server is running to remove and replace PCI hot-plug
cards. For any other service activity requiring access to the processor baseboard or I/O backplane,
power the server off, and observe all safety precautions.
Most problems are the result of incorrect system and SCSI subsystem configurations.
To troubleshoot an installation problem, perform the following checks in the order given:
1. Check all cable and power connections, including those in the rack, and so on.
2. Ensure the server is configured properly.
Check the Setup Utility. If the error is a network-related problem, determine if the server
has enough memory and hard disk drive capacity.
3. Verify all cables and boards are securely plugged in to the appropriate connectors or slots.
4. Remove all extra options, such as disk drives, one at a time, checking the affect of each on
the server.
5. Unplug the power cords, wait 20 seconds, plug-in the power cords and restart the server.
6. If a hardware error is suspected, follow these steps:
a. Log users off the LAN and power off the server.
b. Extend the server out of the rack and remove the top cover.
c. Simplify the server to the minimum configuration.
1. The minimum configuration consists of the following:
• One cell
• Two processors
• One quad of memory DIMMS (size 256 MB or larger)
• One MP/SCSI card
• One LAN/SCSI card
• System backplane
• PCI-X backplane
• One BPS
• Two PCI power modules
• Two power cords
7. Remove all third-party options and reinstall them one at a time, checking the server after
each installation.
8. Replace the top cover and reconnect the cables. Boot the server.
If the server does not function properly, see “The Server Does Not Power On” (page 67).
The Server Does Not Power On
To check for power related problems, follow these steps:
Common Installation Problems 67
Page 68
1. Check each BPS LED.
The LED is located in the lower left hand corner of the power supply face. Table 5-3 shows
the states of the BPS LEDs.
A yellow LED indicates that the line cord connections are not consistent with the pwrgrd
settings.
2. Verify that the power supply and both power cords are plugged in to the chassis.
The Server Powers On Then Shuts Off With a Fault Light
Use this checklist to check for the following problems when the server powers on and then off:
1. Ensure that a conductive item has not been dropped or left inside the server chassis.
2. Check the connections on all boards.
3. Check the system backplane for bent pins.
Use the ps command at the Command Menu todisplay detailed power and hardware status
for selected system hardware.
Cell Board Extraction Levers
It is important that both extraction levers on the cell board be in the locked position. Both levers
must be locked in order for the MP torecognize that the cell board is poweredon and functioning
properly.
Power to the cell board should only be removed using the MP:CM> PE command or by shutting
down the partition or server. Therefore, if the levers become unlocked, the partition will not
have a chance to logically shut down, and damage could occur to the operating system.
If the cell board is powered on and one lever becomes unlocked, the cell board stays powered
on. However, if the cell board is powered off, it does not power on until the cell board is extracted,
reinserted, and both levers are in the locked position.
The lever status can be determined by issuing the MP:CM> DE command and viewing the power
status of the cell board controller (PDHC). The “ready” bit is true only when both levers are
locked and all VRMs are installed. Use this status to determine if both levers are locked, and the
cell board is properly installed in the chassis. For a sample of the output, see Figure 5-1. If the
state is RDY (all caps), it means that the “ready bit” is true. If the state is rdy (lower case) it means
that the “ready bit” is false. The meaning of each of these states is listed below.

Server Management Subsystem Hardware Overview
Server management for the HP 9000 rp7420 server is provided by an MP on the core I/O board.
The server management hardware is powered by standby power that is available whenever the
server is plugged into primary AC power. This enables service access even if the DC power to
the server is switched off.
The MP communicates with the server subsystems, sensors, and PDC by internal buses. It also
communicates with the operating console and session gettys by universal asynchronous
receiver-transmitters (UARTs) on the core I/O PCI bus.
Connection to the management processor is by way of two I/O paths:
• An RS-232 port for a local terminal
• An RS-232 port for a modem connection
• A 10/100/1000 baseT LAN port (Web console)
When the server is configured with one core I/O board, that board must be in slot 0, since the
primary MP is always the MP on the core I/O board in slot 0.
When the server is configured for two partitions, it must contain two core I/O boards, one for
each partition. It also contains two MPs. In this case, the MP in slot 0 is the primary MP and
provides all of the server management functions. The MP on the core I/O board in slot 1 is a
secondary MP and redirects the operating system gettys to the primary MP over an internal
MP-to-MP link. All external connections to the MP must be to the primary MP in slot 0. The
secondary MP ports are disabled.
For high availability (HA), the server powers on and powers off without an MP. Booting HP-UX
without an MP depends on the ability of the operating system to boot without a console getty.
Thus, in a two-partition system, the partition with a failed MP might not boot, since the MP
provides the console getty.
The server configuration cannot be changed without the MP.
78 Troubleshooting
Page 79
Resetting the MP through a modem connection can cause Admin^M to display on every Enter
keystroke. Attempting a modem reset (MP command MR) does not clear this incorrect response.
This is not experienced with a telnet connection.
To regain control with a new Login prompt, follow these steps:
1. Enter Admin (case sensitive) and press < enter > < ctrl + enter > keys.
2. A new Login prompt is created.
3. To move on to the Password prompt, re-enter Admin < ctrl + enter >.
4. To reach the Main Menu, enter Admin < ctrl + enter >.
This fixes the ^M problem. The issue returns if the MP is reset through the modem.
Server Management Overview
Server management consists of four basic functional groups:
• Chassis management
• Chassis logging
• Console and session redirection
• Service access
Chassis Management
Chassis management consists of control and sensing the state of the server subsystems:
• Control and sensing of bulk power
• Control and sensing of DC-to-DC converters
• Control and sensing of fans
• Control of the front panel LEDs
• Sensing temperature
• Sensing of the power switch
• Sensing chassis intrusion
• Reading FRU PROMS
Chassis Logging
Chassis logging consists of maintaining logs of chassis codes:
• Boot codes
• Activity codes
• Error codes
Console and Session Redirection
Console and session redirection enables the console and session terminals to be connected over
the RS-232 port, a modem, or a LAN connection (web console).
Service Access
Service access enables access to and control of the server state. Service access is secured by a
password. Service access functions include the following:
• Access to chassis logs
• Configuration of partitions
• Control for online addition and replacement
• Access to the virtual front panel
• Transfer of control and reset
Server Management Overview 79
Page 80
Server Management Behavior
This section describes how the system responds to over-temperature situations, how the firmware
controls and monitors fans, and how it controls power to the server.
Thermal Monitoring
The manageability firmware is responsible for monitoring the ambient temperature in the server
and taking appropriate action if this temperature becomes too high. To this end, the ambient
temperature of the server is broken into four ranges: normal, overtemp low (OTL), overtemp
medium (OTM), and overtemp high (OTH). Figure 5-11 shows the actions taken at each range
transition. Actions for increasing temperatures are shown on the left; actions for decreasing temps
are shown on the right.
Figure 5-11 Temperature States
On large temperature swings, the server transitions through all states in order. It might go to the
following state immediately, but each of the preceding actions occur. If the temperature reaches
the highest range, the server be shuts down immediately by the manageability firmware.
Fan Control
There are three sets of fans in the system: those on the I/O bay, the front and rear fans that are
connected to the main backplane, and those on the cell boards. The front fans run on standby
power, and run any time AC input power is supplied to the server. All of the fans turn on when
48 V power is supplied to the system.
As shown in Figure 5-11, the fan behavior is related to the temperature state. The fans go to high
speed when the ambient temperature is anywhere above the normal operating range. The front
and rear fans go to high speed any time a chassis intrusion switch is triggered when removing
a side cover.
Altimeter Circuit
The PCI-X backplane contains an altimeter circuit. This circuit is used to adjust the chassis fan
speeds for the operating altitude at power on and during MP initialization. The chassis fans
consist of the nine front fans, twelve rear fans, andthe six PCI-X I/O assembly fans.If an altimeter
failure is detected, the information is logged as an Event ID then propagated to the OS level to
be picked up by monitoring diagnostics.
The altimeter circuit is checked at power on by the MP. If an expected value is returned from
the altimeter circuit, the altimeter is determined good. The altimeter reading is then set in
non-volatile random access memory (NVRAM) on board the core I/O card. If the value is ever
lost like for a core I/O replacement, the NVRAM will be updated at next boot provided the
altimeter is functioning normally. If the altimeter has failed, and the stable storage value has
been lost because of a core I/O failure or replacement, the MP will adjust the fan speeds for
sea-level operation.
80 Troubleshooting
Page 81
NOTE: Fans driven to a high RPM in dense air cannot maintain expected RPM and will be
considered bad by the MP leading to a “False Fan Failure” condition.
Power Control
If active, the manageability firmware is responsible for monitoring the power switch on the front
panel. Setting this switch to the ON position is a signal to the MP to turn on 48 V DC power to
the server. The PE command can also be used to send this signal. This signal does not always
generate a transition to the powered state. The following conditions prevent the manageability
firmware from applying 48 V DC power to the server:
• Insufficient number of active bulk power supplies
• Insufficient number of I/O fans
• Insufficient number of main fans
• Ambient temperature is in an OVERTEMP HIGH condition
Unless one of the following conditions occurs, 48 V DC power to the server is maintained:
• A main fan failure causes there to be an insufficient number of main fans.
• A I/O fan failure causes there to be an insufficient number of I/O fans.
• Ambient temperature reaches an OVERTEMP HIGH condition.
• The front panel power switch is turned OFF.
• The PE command is issued to the manageability firmware to turn off power to the server
cabinet.

6 Removing and Replacing Server Components
This chapter describes how to shut down nPartitions, power off the server, and remove and
replace hardware components in the server.
HP 9000 rp7420 Server Customer Replaceable Units
These procedures are intended for use by trained and experienced service personnel only.
Hot-Pluggable CRUs
A Customer Replaceable Unit is hot-pluggable if it can be removed from the chassis while the
system remains operational, but requires software intervention before removing the CRU.
The following hardware components are hot-pluggable CRUs:
• Disk Drive
• PCI/PCI-X Card
Hot-Swappable CRUs
A CRU is hot-swappable if it can be removed from the chassis while the server remains operational
and requires no software intervention before removing the CRU.
The following list identifies the hot-swappable CRUs in the HP 9000 rp7420 server.
• Front Smart Fan Assembly
• Rear Smart Fan Assembly
• PCI-X Fan Assembly
• BPS
Other CRUs
To remove and replace the CRUs that are neither hot-pluggable, nor hot-swappable, you must
shut HP-UX off in the nPartition where the CRU resides, and you must power the CRU off before
removing it. For detailed instructions, see “Powering Off Hardware Components and Powering
On the Server” (page 84).
These CRUs include:
• CD/DVD/DAT Drive
• PCA Front Panel Board
• PCI Power Module
Safety and Environmental Considerations
WARNING! Before proceeding with any installation, maintenance, or service on a system that
requires physical contact with electrical or electronic components, be sure that either power is
removed or safety precautions are followed to protect against electric shock and equipment
damage. Observe all WARNING and CAUTION labels on equipment. All installation and service
work must be done by qualified personnel.
Communications Interference
HP system compliance tests are conducted with HP supported peripheral devices and shielded
cables, such as those received with the system. The system meets interference requirements of
all countries in which it is sold. These requirements provide reasonable protection against
interference with radio and television communications.
HP 9000 rp7420 Server Customer Replaceable Units 83
Page 84
Installing and using the system in strict accordance with HP's instructions minimizes the chances
that the system will cause radio or television interference. However, HP does not guarantee that
the system will not interfere with radio and television reception.
Take these precautions:
• Use only shielded cables.
• Install and route the cables according to the instructions provided.
• Ensure that all cable connector screws are firmly tightened.
• Use only HP supported peripheral devices.
• Ensure that all panels and cover plates are in place and secure before system operation.
Electrostatic Discharge
HP systems and peripherals contain assemblies and components that are sensitive to ESD. To
prevent component damage from static electricity, carefully observe the precautions and
recommended procedures in this manual.
CAUTION: Connect to ground with a wrist strap. Connection can be made to any grounded
metal assembly in the cabinet. Both you and the electronic devices must be grounded to avoid
static discharges that can cause damage.
To prevent component damage from static electricity, take these precautions:
• Prepare an ESD-safe work surface large enough to accommodate the various assemblies
handled during the upgrade. Use a grounding mat and an anti-static wrist strap, such as
those included in the ESD Field Service Kit, Part number A3024-80004.
• The anti-static bag cannot function as a static dissipating mat. Do not use the anti-static bag
for any other purpose than to enclose a product.
• Treat all assemblies, components, and interface connections as static sensitive.
• When unpacking cards, interfaces, and other accessories that are packaged separately from
the system, keep the accessories in the conductive plastic bags until they are ready to be
installed.
• Avoid working in carpeted areas, and keep body movement to a minimum while installing
accessories.
Powering Off Hardware Components and Powering On the Server
When you remove and replace hardware, you may need to power off hardware components as
part of the remove and replace procedure.
This section gives details on how to power hardware components off and on.
Powering Off Hardware Components
To power off individual components or the entire cabinet, follow these steps:
1. Log in to the MP of the server.
2. If the component you will power off is assigned to an nPartition, then use the Virtual Front
Panel (VFP) to view the current boot state of the nPartition.
You must shut down HP-UX on the nPartition before you power off any of the hardware
assigned to the nPartition.
When you are certain the nPartition is not running HP-UX, you can power off components
that belong to the nPartition.
84 Removing and Replacing Server Components
Page 85
NOTE: Partition configuration information is available on the HP website at http://
docs.hp.com. For more detail, see the HP Systems Partition Guide: Administration for
nPartitions.
3. Access the MP Command menu.
From the MP Main menu, enter CM to access the Command menu.
4. To check details about the hardware component you plan to power off, use the MP Command
menu PS command.
The PS command enables you to check the status of the cabinet, system backplane, MP core
I/O, PCI power domains—or bricks—in the I/O card cage, and cells.
5. Use the MP Command menu PE command to power off the hardware component.
You can power on or off the cabinet (including all cells and I/O in the cabinet) using the PE
command, as well as individual cells along with their associated I/O domain, or PCI power
domains (bricks).
Using the Command menu PE command to manage cabinet power is equivalent to using
the front panel power switch.
6. If you need to disable all power in the entire cabinet, you also must disconnect all power
cords to disable all housekeeping power.
IMPORTANT: Because of power redundancy capabilities, it is important that each power
cord plug into its proper receptacle. Label all power cords to indicate which receptacle each
cord plugs in to. Ensure that the cabinet power is powered off before disconnecting any
power cords.
7. Perform the hardware removal and replacement procedure for the powered off component.
Powering On the Server
To power on the system after a repair, follow these steps:
1. If needed, reconnect all power cords to the appropriate receptacles and power on the system.
2. To power on the hardware component that was powered off and replaced, use the MP
Command menu PE command.
3. To verify that power is enabled to the newly replaced part, use the PS command.
For example; enter C from within the PS command to select cell.
To power on the entire cabinet if power is absent from the part, enter the PE command and
select T.
NOTE: You may need to allow time for some components to complete power on self test
(POST) before a complete status is available.
4. Reboot each nPartition. See Appendix D “Operating System Boot and Shutdown”.
NOTE: Partition configuration information is available on the HP website at http://
docs.hp.com. For more detail, see the HP Systems Partition Guide: Administration for
nPartitions.
5. Verify system functionality by using the Online Diagnostic Support Tools Manager (STM)
exerciser.
