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.
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.
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.
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.

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 Board Interface. The buses include two Front Side Buses (FBS0 and FBS1), a Memory (MID) bus, a Crossbar (XB) bus, and an I/O bus.
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 Platform Dependant Hardware Controller (PDHC) with associated circuitry. The PDH obtains cell board configuration information from cell board signals and from the LPM on the cell.
Table 1-2 Cell Board CPU Load Order (continued) Number of CPUs Installed Socket 0 Location Socket 1 Location Socket 2 Location Socket 3 Location Six CPU installed CPU or empty CPU installed Empty or CPU Eight CPU installed CPU installed CPU installed CPU installed Figure 1-8 CPU Locations on Cell Board 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.
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.
Figure 1-9 DIMM Slot Layout 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).
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.

• • 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.
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.
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.
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.
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. 2. 3. Measure the voltage between L1 and L2. This is considered to be a phase-to-phase measurement in North 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.
Figure 4-4 Safety Ground Reference Check To measure the voltage, follow these steps: 1. 2. 3. 4. Measure the voltage between B0 and A0. Take the AC voltage down to the lowest scale on the volt meter. Insert one probe into the ground pin for B0. Insert the other probe into the ground pin for A0. 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.

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. 2. 3. 4. Enter Admin (case sensitive) and press < enter > < ctrl + enter > keys. A new Login prompt is created. To move on to the Password prompt, re-enter Admin < ctrl + enter >.
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.
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.

by protecting, for example, against power source failures or accidentally tripped circuit breakers. The server can receive AC input from two different AC power sources. System AC Power Specifications Power Cords Table B-3 lists the various power cables available for use with a HP Integrity rx7620 server. Each power cord is 15 feet (4.5 meters) in length with a IEC 60320-1 C19 female connector attached to one end.
NOTE: 1. “Maximum theoretical power” is used to describe input power at the AC input. It is expressed in Watts and Volt-Amps to take into account power factor correction. The calculated sum is the maximum worst case power consumption for every subsystem in the server. This number will not be exceeded by a properly functioning server for any combination of hardware and software. 2. “Marked electrical power” is the input power measured at the AC input expressed in Volt-Amps.
Each cell area fan cooling is controlled by a smart fan control board, embedded in the fan module plastic housing. The smart fan control board receives fan control input from the system fan controller on the system backplane and returns fan status information to the system fan controller. The smart fan control board also controls the power and the pulse width modulated control signal to the fan and monitors the speed indicator back from the fan. The fan status LED is driven by the smart fan control board.
