Configuring Serial Port Settings

You may configure a CCM port to support one of two types of target devices (TDs): SPC or console. For more information about SPC power control devices, see the SPC Installer/User Guide.

A console TD may be a serial-managed Linux (or other Unix) server, router, firewall or other supported serial device.

By default, CCM ports are configured with the settings listed in Table 3.2.

Most of these settings are standard serial port operating characteristics.

The CLI access character parameter specifies how you access the CLI. For more information, see CLI Mode on page 26.

The Power parameter instructs the CCM appliance to monitor the state of a specified RS-232 control signal. Signal transitions may be configured to trigger SNMP traps. The parameter value indicates an inbound control signal (CTS, DCD or DSR) and the state of that signal (low or high). When the defined signal is true, the CCM appliance interprets it as a power on condition for the attached device; when the signal is false, a power off condition for the device is assumed. The signal specified for flow control may not be used for power control, and vice versa.

Port groups

The CCM appliance supports access control groups which may include one or more serial ports. This feature allows a user account to be granted access to a group of ports using a single specification. Each port may belong to only one group (but multiple ports may belong to the same
