Control panel functions

This information provides a table that shows each control panel function and whether each type of control panel supports it.

There are few functional differences among the remote control panel, virtual control panel, and physical control panel. The main difference is that the physical control panel and the remote control panel, when it is cabled directly to the server, can power up the iSeries™ server. The virtual control panel and the remote control panel, if it is connected through a LAN, cannot power up the server.

The following table describes all of the control panel functions and whether the virtual control panel and remote control panel support them.

The following table lists the code for the control panel functions and the descriptions of the control panel functions.

Notes:
  1. Some control panel functions might not be available on all system types.
  2. The x can be any number 0 through 9, any letter A through F, or a blank.
  3. If you have selected a function, find the selected function in the table below and verify that you have completed the correct function.
  4. If you cannot change the Function/Data display or complete the selected function, contact your service provider.

Note: The remote control panel and virtual control panel recognize the presence of a keystick. If your server uses a keystick, the mode button works with the same functions as the physical control panel, depending on whether or not the keystick is inserted. LAN connected remote control panels need special authority to use the mode button.

If you cannot find the function code in the previous table, the customer support for added features or devices might not have been available when this information was produced. Look for any supplemental unit function code information for the function code you displayed on the control panel.
