PowerEdge R7525. The System Configuration Check operation resulted in the following issue: Comm Error: Riser 1.

Hello Peter_X,

It does seem strange that all had the error after the iDRAC update.

First check that the BIOS is up to date. Update it if not and check results:

PowerEdge BIOS R6525/R7525 Version 2.13.3

If you still have error try these next steps on one of the systems:

Drain flea power:

(shut down, disconnect power cables and Network cables, hold in power button 20 seconds with cords removed).

After flea power drain, system has to set for 3 minutes for DRAC to reset without any power plugged in

During this time would you reseat riser 1 and cables

Then plug in NIC and power but wait 2 minutes before power on to give DRAC time to initialize.

When you boot up, enter the iDRAC Settings and confirm Collect System Inventory on Restart is enabled:

-boot to F2 -> System Setup -> iDRAC Settings -> Lifecycle Controller

Choose: Lifecycle Controller set to Enabled

Collect System Inventory on Restart set to Enabled.

Save exit and reboot

Check if error is still reported.
