Old SAN HQ, self signed certificate using SH1

HI

We have an SAN HQ server, but our security scans are flagging that a cert on the server is using SH1.

The cert was issued by Dell EqualLogic Self-signed, its good until 2041, but its using the old hash.  

What is this cert for exactly and can it be deleted or easily replaced with a new one?  I read maybe its for SupportAssist - We don't use that anymore, so could it just be deleted?

Thanks
