Port Access Prerequisites
Conditions for Serial Port Access
If port sharing is not enabled, then one user at a time can access a device
connected to a serial port.
If port sharing is enabled, multiple users can simultaneously access a device
connected to a serial port. If two users have write access, only the first of the
simultaneously connected users can write to the device. The second user who
connects to the port gets read only access.
For accessing serial ports using the Java applet viewing window, the Java 2
Runtime Environment (J2RE) or later must be installed on the computer and
the Java plug-in must be registered with the browser being used. See the
AlterPath OnSite Installation Guide for details.
Port-access Related Procedures in the
Installation Guide
Procedures for enabling the ActiveX plug-in in the browser, configuring the
correct mouse settings on the servers, and enabling the Java plug-in are
provided in the AlterPath OnSite Installation Guide.
Direct Access to KVM Ports and KVM Port
Authentication
The OnSite administrator can enable direct access to all KVM ports, so that
authorized users can directly log into KVM ports through the Web Manager
login screen. If direct access to KVM ports is enabled, a “port name” field
appears on the Web Manager login screen, as shown in the following figure.
