NOTE: Use the systemctl status dcismeng.service command instead of the init.d
command to check if the iDRAC Service Module is installed on Red Hat Enterprise Linux 7 operating
system.
How to check the version number of the iDRAC Service Module installed in the system?
To check the version of the iDRAC Service Module in the system, do any of the following:
• Click Start → Control Panel → Programs and Features. The version of the installed iDRAC Service
Module is listed in the Version tab.
• Go to My Computer → Uninstall or change a program.
What is the minimum permission level required to install the iDRAC Service Module?
To install the iDRAC Service Module, you must have administrator level privileges.
On iDRAC Service Module version 2.0 and earlier, while installing the iDRAC Service Module, it displays
an error message This is not a supported server. Consult the User Guide for additional information
about the supported servers. How to resolve this?
Before installing the iDRAC Service Module, make sure that the server is a 12th generation PowerEdge
server or later. Also, make sure that you have a 64-bit system.
The following message is displayed in the OS log, even when the OS to iDRAC Pass-through over
USBNIC is configured properly. Why?
The iDRAC Service Module is unable to communicate with iDRAC using the OS to
iDRAC Pass-through channel
iDRAC Service Module uses the OS to iDRAC pass-through over USB NIC feature to establish the
communication with iDRAC. Sometimes, the communication is not established though the USB NIC
interface is configured with the correct IP endpoints. This may happen when the host operating system
routing table has multiple entries for the same destination mask and the USB NIC destination is not listed
as the first one in routing order.

In the example enp0s20u12u3 is the USB NIC interface. The link-local destination mask is repeated and
the USB NIC is not the first one in the order. This results in the connectivity issue between iDRAC Service
Module and iDRAC over the OS to iDRAC Pass-through. To troubleshoot the connectivity issue, make
sure that the iDRAC USBNIC IPv4 address (by default it is 169.254.0.1) is reachable from the host
operating system.
