Security advisories
Lenovo is committed to developing products and services that adhere to the highest security standards in 
order to protect our customers and their data. When potential vulnerabilities are reported, it is the 
responsibility of the Lenovo Product Security Incident Response Team (PSIRT) to investigate and provide 
information to our customers so they may put mitigation plans in place as we work toward providing 
solutions.
The list of current advisories is available at the following location:

Power on the server
After the server performs a short self-test (power status LED flashes quickly) when connected to input power, 
it enters a standby state (power status LED flashes once per second).
The server can be turned on (power LED on) in any of the following ways: 
•  You can press the power button.
•  The server can respond to remote power-on requests sent to Lenovo XClarity Controller via Lenovo 
XClarity Essentials OneCLI, IPMItool, or SSH CLI. 
For example, run the following command on Lenovo XClarity Essentials OneCLI to power on your server: 
OneCli.exe  ospower  turnon  --bmc  USERID:PASSW0RD@host
For more information about running the oossppoowweerr command, see

toolsctr_cli_lenovo/onecli_r_ospower_command.html
.
If the system UEFI power policy is set to “always on”, the system will be powered on automatically when an 
AC source is plugged in.
For information about powering off the server, see “Power off the server” on page 16.
System boot/startup time
The system boot/startup time varies by hardware configurations and may change depending on your server 
configuration and conditions.
•  For typical configurations without PMEM memory modules, it takes about 3 minutes for the system to 
start up.
Configuration example: 2 x processors, 16 x RDIMMs, 1 x RAID adapter, 1 x NIC adapter
•  For configurations with PMEM memory modules installed, it may take up to 15 minutes for the system to 
start up.
Configuration example: 2 x processors, 16 x RDIMMs, 16 x PMEMs, 1 x RAID adapter, 1 x NIC adapter
•  For configurations with PMEM memory modules installed and Intel Volume Management Device (VMD) 
enabled, it may take about 20 minutes or longer for the system to start up.
Configuration example: 2 x processors, 16 x RDIMMs, 16 x PMEMs, 1 x RAID adapter, 1 x NIC adapter
Power off the server
The server remains in a standby state when it is connected to a power source, allowing the BMC to respond 
to remote power-on requests. To remove all power from the server (power status LED off), you must 
disconnect all power cables.
