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.

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
