SERVSWITCH™

4.3.3SCAN MODE

To start scanning (switching from CPU to CPU in a continuous rotation) from the keyboard, press and release the left Control key ([Ctrl]), then press [S]. The ServSwitch will begin scanning sequentially from its currently selected port through the higher-numbered ports, then begin again at CPU Port 1. As it scans, it delays 1 to 999 seconds at each port. (This “Scan Time” is user-selectable; see Section 5.2.6.) To stop scanning, press and release [Ctrl], then press [X]; you can also stop a scan by entering a Select Port command. ServSwitch letter commands are not case-sensitive: You can enter upper- or lower-case letters.

To disable scanning, set the scan time to zero; see Section 5.2.6.

4.3.4KEEP SETTING

The Keep Setting command saves the current state of the next command (Set Screen-Saver Interval) to nonvolatile memory (NVRAM); once you issue this command, the current screen-saver interval becomes the new default interval that’s loaded at power-up. To enter the Keep Setting command, press and release the left Control key, then type [K].

4.3.5SET SCREEN-SAVER INTERVAL

This feature reduces the wear on your shared screen and provides security for your system by blanking the screen when there has been no keyboard activity for a specified length of time. To set the screen-saver interval, press and release the left Control key, type [V] followed by the interval time in seconds (1 to 999, or 0 to disable the screen saver), and press [Enter]. Issue the Keep Setting command after you enter this command.

To reactivate the screen when it’s been blanked, press any key on the keyboard or move the mouse. The default setting of this option is 0 (screen saver disabled).

NOTE

When the ServSwitch is in the Screen-Saver state, all of its SELECT LEDs (the left-hand, red port LEDs) will be OFF.
