Connect to a device through the Console port or using SOL.
  • If the software version of the switching plane is earlier than 5.52, log in to the switching plane CLI through the serial port and then access the BIOS. There is no other way to access the BIOS. If the software version of the switching plane is 5.52 or later, log in to the switching plane CLI over SOL or serial port and then access the BIOS.
  • For the switching plane versions from 5.52 to 6.53 (excluding 6.53), if you access the switching plane CLI over SOL and then the BIOS, the operations such as changing the password and system upgrade through disk formatting cannot be performed on the BIOS. These operations are supported on the BIOS from switching plane version 6.53.
  • For details about how to log in to the device using the console port, see Logging In to the Device Through a Console Port. To use third-party terminal emulation software, set the communication parameters correctly. If the parameter settings are incorrect, the BIOS menu operations will be abnormal if you enter excess characters when operating the third party software through the BIOS menu.
