If I install SharePoint 2010 Service Pack 2 should I also install serivce pack 2 for Fast Search?

Hi

We have a SharePoint 2010 server connected to Fast Search server for SharePoint.

We are planning to install Service Pack 2 for SharePoint server2010 . Does this have any impact on the Fast search server? Should we install Service Pack 2 for Fast Search server as well?

Regards
