• 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.
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
sever 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.
If not:
• Change the iDRAC USBNIC address on a unique destination mask.
• Delete the entries that are not required from the routing table to make sure that USB NIC is chosen by
route when the host wants to reach the iDRAC USB NIC IPv4 address.
When uninstalling iDRAC Service Module from a VMware ESXi server, the virtual switch is named as
vSwitchiDRACvusb and port group as iDRAC Network on the Vsphere client. How to delete them?
While installing iDRAC Service Module VIB on a VMware ESXi server, iDRAC Service Module creates the
vSwtich and Portgroup to communicate with iDRAC over the OS to iDRAC Pass-through in USB NIC
