iDRAC allows multiple sessions for the same user. After a user has created the maximum number of allowed sessions, other

users cannot log in to the iDRAC. This can cause a Denial of Service for a legitimate administrator user.

In case of session exhaustion, perform the following remedies:

● If webserver-based sessions are exhausted, you can still login via SSH or local RACADM.

● An administrator can then terminate existing sessions using racadm commands (racadm getssninfo; racadm

closessn -i <index>).

Secure default password

All supported systems are shipped with a unique default password for iDRAC, unless you choose to set calvin as the password

while ordering the system. The unique password helps improve the security of iDRAC and your server. To further enhance

security, it is recommended that you change the default password.

The unique password for your system is available on the system information tag. To locate the tag, see the documentation for

your server at https://www.dell.com/support.

NOTE: For PowerEdge C6420, M640, and FC640, the default password is calvin.

NOTE: Resetting iDRAC to the factory default settings reverts the default password to the one that the server was

shipped with.

If you have forgotten the password and do not have access to the system information tag, there are a few methods to reset the

password locally or remotely.

Resetting default iDRAC password locally

If you have physical access to the system, you can reset the password using the following:

● iDRAC Setting utility (System Setup)

● Local RACADM

● OpenManage Mobile

● Server management USB port

● USB-NIC
