VNC Server

The Linux GUI can be accessed remotely over the network since there is a VNC server installed in the

Linux. The server is preconfigured and ready to use, but it is off by default. Use the command bellow to start VNC server:

The following command stops VNC server:

# vncserver -kill :1

6.3 Graceful Shutdown Support

Graceful shutdown provides a way of gracefully shutting down the OS running on the board once payload deactivation request from uTCA Carrier is received due to explicit deactivation command or AMC handle opened.

Graceful shutdown a result of cooperation of different components of AMC design which are described below:

1. IPMI Controller supports a. OEM IPMI commands which allow the user to enable/disable graceful shutdown support b. Read the Quiesced state of the AMC to determine whether AMC deactivation has been requested by uTCA Carrier Manager c. Monitor of CPU power state to detect system shutdown completion

2. Hardware support a. I2C path to payload CPU which enables OS communication to IPMI Controller

3. Application running on OS side a. Performs AMC Quiesced state monitoring through i2c using OEM IPMI commands and gracefully shuts down the OS once deactivation is requested by uTCA Carrier Manager.
