Chapter 7

Configuring the serial ports for diagnostics

You can use one of the library’s serial ports and a terminal emulation program (such as CHSTERM) to access the library firmware. The console interface, also referred to as the Diagnostic Console, allows you to view information about the library, perform diagnostics tests, create diagnostic listings, and download new firmware.You can also use the library’s serial ports to perform diagnostics on the tape drives.

The following table illustrates the functions you can perform using the serial ports. As the table indicates, unless you want to control the motion of the CHM, you do not need to switch to 9-Pin or 25-Pin Port control mode (for narrow libraries) or 25/9 Pin control mode (for wide libraries).
