Fabric Manager Installation

Hello, I am trying to install fabricmanager and the service is failing to start up. I have a fresh google cloud ubuntu VM instance with 4 A100 GPUs. I am wishing to take advantage of the NVSwitch features for multiple GPUs.

Machine : Ubuntu 18.04.6 LTS
Fabric Manager version is : 450.80.02

$ sudo systemctl start nvidia-fabricmanager.service

Job for nvidia-fabricmanager.service failed because the control process exited with error code.
See "systemctl status nvidia-fabricmanager.service" and "journalctl -xe" for details.
$ sudo systemctl status nvidia-fabricmanager.service
