Telnet access is available to that controller, using its IP address.
Telnet will have to be enabled already. If not,
In the Array Management window's Physical tab, select the Controller you wish to grant Telnet access to. Navigate to Hardware > Controller > Change > Remote Login. Note: This will be made unavailable if a controller is not highlighted in the Physical tab. In the Change Remote Login window that pops up, verify that the Enable TELNET access to Controller box is checked.
