CHAPTER 2: I NSTALLATION 7All target servers must be configured to one of the display resolutions supported by Dominion KX, as listedin the beginning of this chapter. The most popular supported resolutions for Sun machines are:1024x768@60Hz1024x768@70Hz1024x768@75Hz1024x768@85Hz1152x900@66Hz1152x900@76Hz1280x1024@60HzTarget servers running the Solaris operating system must output VGA video (H-and-V sync, not compositesync). To change your Sun video card output from composite sync to the non-default VGA output, firstissue the Stop+A command to drop to bootprom mode. Then, issue the command:setenv output-device screen:r1024x768x70to change the output resolution. Issue the “boot” command to reboot the server.Alternatively, you may contact your Raritan representative to purchase a video output adapter. 13W3 Sunswith composite sync output require APSSUN II Guardian converter for use with Dominion KX. HD15Suns with composite sync output require the 1396C converter to convert from HD15 to 13W3 and anAPSSUN II Guardian converter to support composite sync. HD15 Suns with separate sync output requirean APKMSUN Guardian converter for use with Dominion KX.Apple Macintosh SettingsFor target servers running an Apple Macintosh operating system, no specific mouse setting is required.However, when using Dominion KX to access and control your target server, you must set the DominionKX client (Raritan Remote Client) to “single cursor” mode (see Chapter 3: Raritan Remote Client,Remote KVM Console Control, Single Mouse Mode).Dual cursor mode is not supported for Macintosh target servers; the two mouse pointers will not appear insync if you attempt to control a Macintosh server via Dominion KX in dual cursor mode.Configuring Network Firewall SettingsIf you wish to access Dominion KX through a network firewall, your firewall must allow communicationon TCP Port 5000. Dominion KX can also be configured to use a different TCP port of your designation(see Chapter 4: Administrative Functions, Network Configuration).Optional: To take advantage of Dominion KX’s web-access capabilities, the firewall must also allowinbound communication on TCP Port 443 – the standard TCP port for HTTPS communication. To takeadvantage of Dominion KX’s automatic redirection of HTTP requests to HTTPS (i.e., so users may typethe more common, “http://xxx.xxx.xxxx” instead of “https://xxx.xxx.xxxx”), then the firewall must alsoallow inbound communication on TCP Port 80 – the standard TCP port for HTTP communication.
