PowerVault NX3100 - error in Main System Chassis

I need assistance with troubleshooting this powervault -  Tag # 2V3RNQ1

The unit is displaying a blinking orange light on the front of the unit.

I performed a restart/reboot on the server on Jan 2, 2016 because I could not see three external disk drives on the unit that are connected to a PCIE USB 3.0 card.   After rebooting they displayed and worked successfully.

In Dell Open Manage Server Admin there is a red x beside Main System Chassis. When this is expanded there is a red x by Hardware Log.  When this is expanded below are the messages:
