To Access Help

To use online help, the help file must be configured. Use the command:
set help=help-filename
where help-filename is the name of a help file stored in flash.
Help files have an .hlp extension. To see a list of files stored in flash, use the
command:
show file
To display a list of help topics, use the command:
help
To display help on a specific topic, use the command:
help topic
where topic is the name of a help topic.
You can also type a question mark (?) at the end of a partially completed
command to see a list of valid options.

Startup Procedure

When the switch starts up following either a power cycle or an operator-
initiated reboot (using the reset button or restart command), it performs a
series of self tests and sends messages to the terminal or PC connected to the
RS-232 Terminal Port. After the switch successfully starts, a prompt is
displayed for you to log in. See the Getting Started chapter in the Rapier Series
®
Switch AlliedWare Operating System Software Reference for more information
about logging in.
At startup, you can choose to run either the software version stored in the
EPROM or the software version in the flash file system specified by the
installation parameters previously set using the set install command.
All code is executed in system RAM. At power-up, the boot code is loaded
from EPROM to RAM. The boot code checks the installation parameters then
reloads RAM with the selected temporary, preferred, or default install version
stored in the flash file system and runs this code.
The version is uncompressed as it loads to RAM. This may take 10 to 30
seconds. At this point, any required patches are loaded from the flash file
system. Any patch is also uncompressed as it loads to RAM. This procedure
ensures that the code runs at maximum speed, and allows updates to be made
to the code. Updates can be downloaded over the network from a TFTP server
and stored in the flash file system until required at power-up.
To download software onto the switch, see the Managing Configuration Files and
Software Versions chapter in the Rapier Series Switch AlliedWare
System Software Reference.
All software, patches, and configuration settings are stored as files in flash
memory. Typically, the following files are present in the flash file system:
The current installed software version. Additional software versions may
■
also be present.
The current installed patch, if any. Additional patches may also be present.
