Embodiment 1
[0015] To initialize the server processor, the management configuration chip first initializes its own network address, then sets and initializes the I2C bus address, the management configuration chip starts to read and write network parameters to the memory, and at the same time modifies the network address flag bit; then, configures the target chip to obtain bus control At the same time, initialize and configure the I2C bus address, read the data in the memory, first judge whether the flag bit is a new network configuration, if it is a new network configuration parameter, modify its own network address according to the obtained data, otherwise keep its own network configuration. change, and re-read the memory for judgment processing.
Embodiment 2
[0017] Based on Shenwei 1610-16 core server processor, the main frequency is 1.6GHz, the memory is 16GB, fully equipped with 8 server computing units, 2 switching units, 2 management control units and 3 redundant power supply units; the memory adopts AT24C02C series Row CMOS E 2 PROM, the management configuration chip is ASPEED2400 chip, and the configuration target chip is BCM53003 chip.
[0018] The method steps are as follows:
[0019] For Shenwei 1610-16 core server processor power-on initialization, ASPEED2400 first initializes its own network address, and then sets and initializes the I2C bus address, ASPEED2400 starts to E 2 The PROM reads and writes network parameters, and modifies the network address flag at the same time; then, BCM53003 obtains the bus control right, initializes and configures the I2C bus address at the same time, and reads the E 2 For the data in the PROM, first judge whether the flag bit is a new network configuration, if it is a new network conf...
Embodiment 3
[0021] Based on the Shenwei 1610-16 core server processor, the main frequency is 1.6GHz, the memory is 32GB, fully equipped with 16 server computing units, 2 switching units, 2 management control units and 3 redundant power supply units; the memory adopts AT24C02C series Row CMOS E 2 PROM, the management configuration chip is ASPEED2400 chip, and the configuration target chip is BCM53003 chip.
[0022] The method steps are as follows:
[0023] For Shenwei 1610-16 core server processor power-on initialization, ASPEED2400 first initializes its own network address, and then sets and initializes the I2C bus address, ASPEED2400 starts to E 2 The PROM reads and writes network parameters, and modifies the network address flag at the same time; then, BCM53003 obtains the bus control right, initializes and configures the I2C bus address at the same time, and reads the E 2 For the data in the PROM, first judge whether the flag bit is a new network configuration, if it is a new network...
