Management Processor Monitor: Troubleshooting

Table 9-7:Optional Environment Variables

Variable1:

 

Description:

 

app_lock_base

 

Assigns where to start block lock protection at the base of NOR (soldered) flash.

 

 

If assigned region does not fall within the NOR flash area, no user/application

 

 

locking will occur, except for the monitor block-locking protection.

 

 

 

app_lock_size

 

Size of user NOR (soldered) flash protection area.

 

 

 

bootverifycmd

 

Sets the U-Boot boot command that is used to execute the primary and

 

 

secondary application images when using the bootv command. If not defined,

 

 

bootv uses the U-Boot go command as the default.

 

 

 

carrier_num

 

This is a slot within a shelf defined by the zone 1 hardware address

 

 

corresponding to the logical slot address.

 

 

 

e_keying

 

Determines whether switch ports should be configured.

 

 

 

pci_memsize

 

Sets the amount of SDRAM memory made available on the PCI bus. The

 

 

minimum setting is 16 megabytes. If not set, 128 MB of SDRAM are available

 

 

over PCI. This parameter takes a hex value.

 

 

Valid options: all, size in hex (0x8000000=128 MB)

 

 

 

pram

 

This memory region is at the very top of memory and can be reserved—not to be

 

 

cleared on start-up or reset. Default size of the protected memory region is 0.

 

 

pram is defined in kilobytes and is a base 10 number. The smallest allowable size

 

 

is 4 (4 KB) and the largest recommended size is 32768 (32 MB). pram should be 4

 

 

KB aligned, otherwise U-Boot will round pram to the next 4 KB size.

 

 

 

sec_bootargs

 

Sets the boot arguments that are passed into the secondary application images

 

 

when using the bootv command. If not defined, bootv will pass the bootargs

 

 

configuration parameters into both the primary and secondary application

 

 

images.

 

 

 

shelf_addr

 

ATCA chassis shelf address provided by shelf-manager

 

 

Not defined in default configuration—reported at bootup from the IPMC

 

 

 

1.The moninit command does not initialize these variables. Each parameter is only defined if a change from the default setting is desired and is not defined after initialization of the environment variables.

TROUBLESHOOTING

To bypass the full board initialization sequence, attach a terminal to the console located on the front of the ATCA-9305. Configure the terminal parameters to be:

9600 bps, no parity, 8 data bits, 1 stop bit

Reset the ATCA-9305 while holding down the ‘s’ key. Pressing the ‘s’ key forces a configura- tion based on default environment variables.

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.
