Power supply CRU failures are identified visually by a single green LED that is turned off when one or both of the power supplies fail. Power supply failures are also logged as IPMI events by voltage sensor logic and identified as power supply CRU failures on the front LED panel.

The I/O VRM CRU, located beside the core I/O board CRU, provides all I/O subsystem dc power.

Power Subsystem Behavior

For rx3600 servers, each bulk power supply CRU provides 1200 watts of dc power from a nominal 120 V ac 50-60 Hz. The Baseboard Management Controller (BMC) chip located on the core I/O board CRU controls the flow of +12 V dc power to the server CRUs. You can both control and display power supply status remotely with the iLO 2 MP pc and ps commands, respectively.)

The server powers on as follows:

•The Power LED on the front panel glows steady amber when one or two bulk power supplies are plugged into nominal ac voltage. The +3.3 VDC housekeeping voltage comes on and stays on whenever ac power is present.

•The BMC, iLO 2 MP, flash memory, and chassis intrusion circuits are reset after the +3.3 V dc housekeeping voltage stabilizes.

•The BMC monitors the power button on the front panel.

•When the power button is pressed or when a Wake on LAN (WOL) signal is asserted, the BMC signals the bulk power supplies to fully power on.

•+12 V dc comes up and all the cooling fans and the various VRMs power on sequentially.

•The BMC signals that the server is ready to come out of reset.

•The server comes out of reset.

•The zx2 chip resets all components connected and the server begins the boot process.

System Power LED/Switch

The front panel system power LED indicates system power status. It is incorporated with the power button.

The power button has a momentary switch that is recessed to prevent accidental powering on or off.

If the OS is running, press the power button for less than four seconds to gracefully shut down the OS and power off the system. Press the power button for greater than four seconds to power off the system immediately. When the server is booting (before the system has passed EFI_EXIT_BOOT_SERVICES), the BMC powers off the server immediately when you press the button.

If the OS is not running or is hung, or the BMC is not responding, press and hold the power button for more than four seconds to power off the system.

To ensure that the system powers on correctly, the power button must not be pressed again for four seconds after it powers off.

INTEGRITY RX3600 specifications

The HP Integrity RX3600 is a high-performance server designed to address the demanding needs of enterprises that require robust computing capabilities, reliability, and scalability. Part of the HP Integrity server family, the RX3600 is built on the Itanium architecture, which is known for its exceptional processing power and advanced features that support mission-critical applications.

One of the main features of the RX3600 is its capability to handle multiple workloads with ease. The server supports up to 64 GB of RAM, allowing for efficient multitasking and enhanced performance in data-intensive environments. Its modular design also enables organizations to scale up their systems by adding additional memory or processors as needed, making it a flexible choice for growing businesses.

The RX3600 is equipped with HP's Integrity Virtual Machines (VMs), which provide virtualization capabilities that allow businesses to run multiple operating systems and applications on a single physical server. This not only maximizes resource utilization but also simplifies management by reducing the number of physical servers required in the data center.

Another significant characteristic of the RX3600 is its advanced reliability features. The server is designed with fault-tolerant components, including redundant power supplies and cooling systems. This ensures that the server remains operational even in the event of hardware failures. Additionally, HP's Error Correction Code (ECC) memory helps detect and correct data corruption, further enhancing the system's reliability.

For security, the HP Integrity RX3600 includes built-in features such as Secure Boot, which ensures that the server boots using only trusted firmware and software. This protects against unauthorized changes and vulnerabilities that could compromise data integrity.

In terms of connectivity, the RX3600 offers multiple I/O options, including advanced networking capabilities that support high-speed data transfer and improved bandwidth. This is critical for organizations that rely on data-intensive applications and need to maintain seamless connectivity.

Furthermore, the server supports a range of operating systems, including HP-UX and Linux, making it adaptable to various enterprise environments. Its robust performance, reliability, and scalability make the HP Integrity RX3600 an ideal choice for businesses looking to optimize their IT infrastructure and support their critical workloads with confidence.
