NOTE: To ensure a secure connection, Dell recommends using TLS 1.1 and higher.

Conguring TLS using web interface

1. Go to Overview → iDRAC Settings → Network.

2. Click the Services tab and then click Web Server.

3. In the TLS Protocol drop-down, select the TLS version and click Apply.

Conguring TLS using RACADM

To check the version of TLS congured:

racadm get idrac.webserver.tlsprotocol

To set the version of TLS:

racadm set idrac.webserver.tlsprotocol <n>

<n>=0 TLS 1.0 and Higher

<n>=1 TLS 1.1 and Higher

<n>=2 TLS 1.2 Only

Using VNC client to manage remote server

You can use a standard open VNC client to manage the remote server using both desktop and mobile devices such as Dell Wyse

PocketCloud. When servers in data centers stop functioning, the iDRAC or the operating system sends an alert to the console on

the management station. The console sends an email or SMS to a mobile device with required information and launches VNC viewer

application on the management station. This VNC viewer can connect to OS/Hypervisor on the server and provide access to

keyboard, video and mouse of the host server to perform the necessary remediation. Before launching the VNC client, you must

enable the VNC server and congure the VNC server settings in iDRAC such as password, VNC port number, SSL encryption, and

the time out value. You can congure these settings using iDRAC Web interface or RACADM.

NOTE: VNC feature is licensed and is available in the iDRAC Enterprise license.

You can choose from many VNC applications or Desktop clients such as the ones from RealVNC or Dell Wyse PocketCloud.

Only one VNC client session can be active at a time.

If a VNC session is active, you can only launch the Virtual Media using Launch Virtual Console and not the Virtual Console Viewer.

If video encryption is disabled, the VNC client starts RFB handshake directly, and a SSL handshake is not required. During VNC client

handshake (RFB or SSL), if another VNC session is active or if a Virtual Console session is open, the new VNC client session is

rejected. After completion of the initial handshake, VNC server disables Virtual Console and allows only Virtual Media. After

termination of the VNC session, VNC server restores the original state of Virtual Console (enabled or disabled).

NOTE:

• When iDRAC NIC is in shared mode and the host system is power cycled, the network connection is lost for a few

seconds. During this time, if you perform any action in the active VNC client, the VNC session may close. You must wait for

timeout (value congured for the VNC Server settings in the Services page in iDRAC Web interface) and then re-establish

the VNC connection.

• If the VNC client window is minimized for more than 60 seconds, the client window closes. You must open a new VNC

session. If you maximize the VNC client window within 60 seconds, you can continue to use it.

Conguring VNC server using iDRAC web interface

To congure the VNC server settings:

1. In the iDRAC Web interface, go to Overview → iDRAC Settings → Network → Services.
