System Management: IPMC Watchdog Timer Commands

Reset Watchdog Timer Command

The Reset Watchdog Timer command is used for starting and restarting the Watchdog Timer from the initial countdown value that was specified in the Set Watchdog Timer com- mand.

If a pretime-out interrupt has been configured, the Reset Watchdog Timer command will not restart the timer once the pretime-out interval has been reached. The only way to stop the timer once it has reached this point is via the Set Watchdog Timer command.

Set Watchdog Timer Command

The Set Watchdog Timer command is used for initializing and configuring the watchdog timer. The command is also used for stopping the timer.

If the timer is already running, the Set Watchdog Timer command stops the timer (unless the “don’t stop” bit is set) and clears the Watchdog pretime-out interrupt flag (see Get Mes- sage Flags command in the IPMI specification v1.5). IPMC hard resets, system hard resets, and the Cold Reset command also stop the timer and clear the flag.

Byte 1: This selects the timer use and configures whether an event will be logged on expiration.

Byte 2: This selects the time-out action and pretime-out interrupt type.

Byte 3: This sets the pretime-out interval. If the interval is set to zero, the pretime-out action occurs concurrently with the time-out action.

Byte 4: This clears the Timer Use Expiration flags. A bit set in byte 4 of this command clears the cor- responding bit in byte 5 of the Get Watchdog Timer command.

Bytes 5 and 6: These hold the least significant and most significant bytes, respectfully, of the countdown value. The Watchdog Timer decrement is one count/100 ms. The counter expires when the count reaches zero. If the counter is loaded with zero and the Reset Watchdog command is issued to start the timer, the associated timer events occur immediately.

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.
