Manual Command Entry
You can type commands into the online window. This is recommended only if you are competent with
the 8000 series systems and you know the command you need, or the first-line diagnostics specifically
asks you to type these commands. The most useful commands are:
ls b Show backup log of events before the last power-down of the main processor
ls d Show current main processor log since last power-up (moved to backup log on power loss)
ls l Real-time monitor of processor log
The terminal is a simple implementation and will not refresh the screen until a new line is entered. This
is most evident with ls l; type ctrl-c to exit and press Enter. Teraterm Pro is recommended for full
manual command-line access.
The Main Processor log is available without privileged (password) access, and does therefore not
invalidate any safety protection. A later section describes some of the possible entries in these logs.
