System Management: IPMC Headers

HPM.1 Reliable Field Upgrade Procedure

The HPM.1 upgrade procedure is managed by a utility called the Upgrade Agent. The

Impitool utility is used as an Upgrade Agent for upgrading the ATCA-9305 IPMC firmware.

The Upgrade Agent communicates with the IPMC firmware via the payload serial interface or IPMC-0, and uses the AdvancedTCA commands that are described in the HPM.1 specifica- tion for upgrading the firmware. Updated firmware is packed into an image formatted in compliance with the HPM.1 specification. That image is used by Upgrade Agent to prepare and upgrade the IPMC firmware. The HPM.1 upgrade procedure includes the following steps:

Preparation: This step erases the region in the flash memory where the component image will be writ- ten.

Component Upload: This step is designed to upload the component image via IPMB or payload interface and write it into the flash memory.

Component Activation: This step activates the previously upgraded component. This step can be deferred and per- formed later.

For more details, refer to the HPM.1 specification listed in Table 1-2.

ATCA-9305 specifications

The Emerson ATCA-9305 is a high-performance AdvancedTCA (ATCA) chassis designed to meet the demanding requirements of telecommunications and IT infrastructure. With a focus on scalability, reliability, and flexibility, this equipment is ideal for service providers and enterprises looking to deploy robust applications in a variety of environments.

One of the main features of the ATCA-9305 is its support for high-density blade configurations. The chassis can accommodate up to 14 ATCA blades, enabling the deployment of powerful processing units, communication modules, and storage solutions. This level of density not only maximizes space but also minimizes power consumption, which is crucial for reducing operational costs in large-scale deployments.

The ATCA-9305 is built with a focus on advanced thermal management and redundancy. It employs a sophisticated cooling architecture that ensures optimal airflow across the chassis, preventing overheating during operation. Additionally, the chassis features hot-swappable fans and power supplies, which means that components can be replaced without interrupting the overall system performance. This capability enhances uptime and reliability, which is essential for mission-critical applications.

Another notable characteristic of the ATCA-9305 is its support for various interconnect technologies. The chassis provides robust backplane options that facilitate high-bandwidth communication between blades. It supports Ethernet, PCI Express, and Serial RapidIO, allowing for seamless integration with existing infrastructure and future technologies. This flexibility enables organizations to adapt to changing market demands and technological advancements.

Security features are also a prominent aspect of the ATCA-9305. The chassis incorporates hardware-based security modules that enhance data integrity and protect sensitive information. This is particularly important for service providers who must adhere to strict regulatory compliance standards.

In terms of management and monitoring, the ATCA-9305 is equipped with advanced management capabilities. It supports AdvancedTCA Management Interface (IPMI) and other monitoring protocols, allowing administrators to easily oversee the health and performance of the entire system. This level of visibility aids in proactive maintenance and troubleshooting, effectively reducing downtime.

In conclusion, the Emerson ATCA-9305 is a powerful and versatile chassis that stands out due to its high-density configuration, advanced thermal management, diverse interconnect technology support, robust security features, and comprehensive management capabilities. Its design is tailored for the evolving needs of telecommunications and data center environments, making it a valuable asset for any organization looking to enhance its infrastructure.
