Priority Colo -- Raritan KVM primer


This primer is a guide to using PriorityColo's Raritan KVM interface to remotely access a server console.  This device allows you to interact with a server as though you were physically there with a keyboard, video, and mouse, remotely from any web browser.  If your server is all setup and you are ready to get started with it, then this is the guide for you.




Before starting: to use the Raritan KVM interface, you will need a recent browser, with a functioning Java plugin.  Firefox / Chrome under Linux, Safari under MacOS, and pretty much everything under Windows, should work fine.  




As an alternative, there is a standalone Raritan client for win32, which is supported by Priority Colo.


Navigate to the URL for the device you are hosted on.  (e.g. -- this URL loads the UI inline, instead of opening a popup.)  You will be prompted to accept Raritan's SSL certificate.






Once the applet loads, you will see the main UI for the KVM tool.  This applet will maintain a local profile, remembering any settings you may configure.  It is recommended to use the same browser for all of your KVM operations, simply as a matter of convenience.  (i.e. if you blow away your browser profile, your raritan settings will also be blown.)







Because the applet is based off of a profile, you will not even have the unit you connected to listed yet.  You must add the unit first.  Click on Connection / New Profile (or the "New Profile" button, leftmost on the toolbar).  The "New Connection" dialog box will appear.





Under "Description", enter the short name of the unit (e.g. "raritan-a10").  Next, below "Find Raritan device By:". select the "Host Name" radio button, and enter the fully qualified domain name of the unit (e.g. "")






An entry for the unit will now appear under the Raritan Devices panel.  Double-click it to connect.






The unit will prompt you for your username/password (these are the KVM user/pass which were provided to you).  If you opt to save the username/password, make sure that your browser profile is secured with a password!






If the connection is successful, the device will expand, showing any ports you are authorized to connect to.






Double-click on a port to connect to it:




You should now see an image of the console of the system attached to that port, in the Channel panel.  You may interact with the console using the keyboard and mouse, not unlike a browser-based VNC session.


* If the port you are looking for is not visible under the connected unit, the system may be powered off (the kvm hides powered-off systems).  See the APC guide for instructions on powering on your system.

* The interface has a few odd quirks.  If you navigate away from the browser window and then return, you may find keyboard input stops working.  Try clicking on the console window first, to return focus to the applet.

* Most keyboard codes / shortcuts should work, but watch out for shortcuts captured by the local OS!  In particular, there are toolbar buttons for ctrl-alt-del and Esc, the first of which is used often.  (Esc key should work normally though.)

* To disconnect, click the raritan unit, then right-click and select "Disconnect".

* Raritan also offers a stand-alone "Multi-Platform" Client, effectively just a .jar of the web client.  If you experience difficulties getting Java to launch the webUI from your browser, you can try the stand-alone client instead.  Download from here and install: (Note: versions may change the URL on the site, visit and search for "Dominion KX II" support, to locate the multi-platform client.)
