NOTE: The MergePoint Unity switch for Dell supports one cascaded switch per target port of the main
switch. You cannot attach more switches to the cascaded switches.
NOTE: Local port cascading is not supported on the MergePoint Unity switch.
2.5 Configuring the MergePoint Unity Switch for Dell
Once all physical connections have been made, you will need to configure the switch for use in the overall
switching system. This can be accomplished in two ways.
To configure the switch using the DSView software:
See the DSView Installer/User Guide for detailed instructions.
To configure the switch using the local UI:
See Network Settings on page 23 for detailed instructions on using the local UI to configure initial network
setup.
2.5.1 Setting up the built-in web server
You can access the switch via an embedded web server that handles most day-to-day switching tasks.
Before using the web server to access the switch, first specify an IP address through the local port on the
back panel of the switch or local UI. See Local and Remote Configuration on page 15 for detailed
instructions on using the user interface for switching.
2.5.2 Connecting to the OBWI through a firewall
For switch installations that use the OBWI for access, four ports must be opened in a firewall if outside
access is desired.
TCP PORT NUMBER FUNCTION
22 Used for SSH for serial sessions to an MPUIQ-SRL module
23 Used for Telnet (when Telnet is enabled)
80 Used for the initial downloading of the KVM Video Viewer (for downloading the Java applet)
443 Used by the web browser interface for managing the switch and launching KVM sessions
2068 Transmission of KVM session data (mouse & keyboard) or transmission of video on switches
4206 Used by the web browser interface for managing the switch and launching HTML5 KVM sessions
Table 2.2 TCP Ports and Functions for the Switch OBWI
In a typical configuration, as shown in the following figure, the user’s computer is located outside of the
firewall, and the switch resides inside the firewall.
