SSL certificate installation

Good day,

I currently have the following kit that I'm trying to install SSL certificates on:

- SC5020F, accessed on web via Unisphere

- PowerEdge FX2, CMC accessed via web

- PowerEdge FC640, iDRAC accessed via web

- DataDomain 3300, System Manager accessed via web

- Force10 S3048 switch

- Dell Networking S4128F-ON

I have tried to follow one article to try configure the certificate on one of the iDRACs of the FC640s, no dice. The link is below to the article i used: https://www.dellemc.com/resources/en-us/asset/analyst-reports/products/servers/idrac9-ssl-renewal-science-0220.pdf (I used the manual method)

This is my first time deploying these so any help I can get with regards to how to do it per product would be very appreciated.

Thank you.
