Read Installation Guidelines and Safety inspection checklist to make sure that you work safely.
Prevent exposure to static electricity, which might lead to system halt and loss of data, by keeping static-sensitive components in their static-protective packages until installation, and handling these devices with an electrostatic-discharge wrist strap or other grounding system.
The firmware of the chassis midplane can be updated via Lenovo XClarity Controller (XCC) and Lenovo XClarity Essentials OneCLI (LXCE OneCLI). Only the caretaker node can perform this update.
By default, the caretaker node is automatically selected by the PSoC firmware on the chassis midplane. To change the chassis caretaker preference, see Configuring the D3 Chassis.
Go to Update the firmware for more information on firmware updating tools.
