Each connected device is identified in different ways in the management software by the port number to which it is connected.The following table shows the default conventions for addressing the device files and port numbers for the AUX ports, KVM ports, serial ports, and PCMCIA slots on the OnSite.
Port Name on Web Manager ttyA[1 | 2] Modem (internal) ttyA 3 ttyK n When a user connects to a KVM port through the Web Manager (KVM over IP), the AlterPath Viewer uses port 5900 by default. If a second IP module exists, port 5901 is used for a second KVM over IP session. Port n ttyS n 7001-7008, 3000 (for the pool of serial ports) ttyM n The TCP port numbers for serial ports are used when a user connects to a serial port using telnet or another connection protocol or when a user connects to the serial port through the Web Manager. When a user connects to a serial port, the Java applet uses the TCP port that is assigned to the port number, for example port 7001 is assigned to serial port 1.The TCP port numbers for KVM ports are used by the AlterPath Viewer when a user connects to a KVM port over the network. By default, when a user connects to a KVM port over the network, the AlterPath Viewer uses port 5900. If a second IP module exists, port 5901 is used for the second AlterPath Viewer launched over IP. You can assign a different port number or numbers through the OSD or the web management interface. Do not assign reserved TCP port numbers 1 through 1024.Special circumstances may require OnSite administrators to configure TCP port numbers different from the defaults. For example, a firewall may block TCP port 5900 or 5901.The OnSite administrator can assign a descriptive alias to each port to identify the connected computer. For example, if a SunBlade server is connected to KVM Port_3, the administrator could define Port_3’s alias to be “SunBlade,” so “Port_3” is replaced in the ports list by “SunBlade.”Note: The list of ports in the OSD displays only 19 characters. If anyone will be using the OSD for KVM port access, keep this in mind. If longer aliases are required at your site, put the information that uniquely identifies the server at the beginning of the alias.The following table provides links to procedures for changing default TCP port numbers and port aliases.
Change the TCP port number assigned to the Java applet Change the TCP port number(s) assigned to the AlterPath Viewer(s) Assign an alias describing the server connected to the KVM port Assign an alias describing the device connected to the serial port
