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).
For detailed information about using the Diagnostic Console and
the serial ports, refer to Exabyte 440 and Exabyte 480 8mm Libraries
