Embodiment 1

[0039] In the fault detection method provided by Embodiment 1 of the present invention, its flow is as follows figure 2 As shown, the execution steps are as follows:

[0040] Step S101: When the management board detects that the service board exists, it allocates a section of memory space for the service board in its own memory space.

[0041] The allocated memory space is used to monitor the status of the service board. This step specifically includes: when the management board detects the existence of the service board, allocate a register partition for storing the register content of the service board and a state partition for storing the status information of the service board for the service board in its own memory space; and establish the assigned The mapping relationship between the registered register partition and the register on the service board, the allocated state partition and the PCIE space of the service board.

[0042] Step S102: the management board monito...

Embodiment 2

[0052] The fault detection method provided by Embodiment 2 of the present invention is as follows: image 3 The modularized device shown is taken as an example for description, where the modularized device includes: a management board and several service boards.

[0053] Wherein, the management board includes a CPU, a PCIE switch chip (PCIE Switch), a memory (Memory), and a complex programmable logic device (Complex Programmable Logic Device, CPLD). The service board includes a CPU (including CPU peripherals such as clock, power supply, memory, etc.) and a service processing module (including specific interface modules). The CPU on the management board is connected to a PCIE Switch through the PCIE bus, and the CPU, memory, and CPLD are connected through the memory interface bus. The PCIE Switch has multiple ports, which are respectively connected to each service board, specifically to the CPU on the service board. The CPU and the service processing module on the service boar...

Abstract

The invention discloses a fault detection method, a modular device and a management board. The method comprises the following steps: when detecting the existence of a service board, the management board distributes a register partition and a state partition for the service board in the memory space, wherein the register partition is used for storing register contents of the service board, and the state partition is used for storing the state information of the service board; the management board establishes mapping relations between the register partition and the register on the service board and between the state partition and the PCIE space of service board; the management board writes the contents in the service board into the register partition through the PCIE bus according to the mapping relations, and allows the service board to write the state information into the state partition through the PCIE space according to the mapping relations; and the management board reads the register contents and state information of the service board from the register partition and the state partition, determines whether the service board fails, and analyzes to locate a fault. The method is simple to realize, can quickly and reliably locate the fault of the service board, and does not need signal communications, thereby saving system resources.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a fault detection method for detecting faults of board cards of modularized equipment and modularized equipment. Background technique [0002] Modular equipment refers to a system composed of various functional modules in a certain combination. For example, a modular routing device or switch may include: a power module, a management board, and several service boards. These different functional modules are connected to each other through the backplane in the chassis to form a modular routing device or switch. The functional modules are relatively independent and closely connected: the power module is mainly responsible for supplying power to the whole machine; the management board is mainly responsible for the management of the whole machine, such as judging which functional modules exist in the whole machine, and monitoring the working status of these functional modules. Chec...
