We have Lambda Blade 8 RTX stuck at initializing with AF code. We tried pulling off the CMOS battery for 2min and restarting it. The system is still stuck at the AF code. Do you think it is a motherboard failure? Please advise. ![image](https://sea1.discourse-cdn.com/flex019/images/transparent.png) ---

If it is a blade it should have IPMI. Ideally you know how to use IPMI and have the network setup. The chassis would have one ‘Ethernet’ labeled IPMI LAN or similar it should get a address via dhcp. And the chassis should have a password. [Where can I find my server's IPMI (BMC) password? | Lambda Docs](https://docs.lambdalabs.com/servers/ipmi-password/) On another Ubuntu Linux machine: $ sudo apt install ipmitool Or from a remote linux machine: $ ipmitool -I lanplus -H IP\_ADDRESS -U ADMIN -P “PASSWORD” sel elist \>& ipmi-sel.txt $ ipmitool -I lanplus -H IP\_ADDRESS -U ADMIN -P “PASSWORD” sdr \>& ipmi-sdr.txt \*\* Where ‘PASSWORD’ would be your IPMI password, and IP\_ADDRESS is your machines BMC/IPMI ip address. The ‘ipmitool sdr’ will show status of components (sensors: temperatures, voltages) The ‘ipmitool sel elist’ will show the event log of what is wrong
