4.2 Shutting Down an RPC III 498

There are two different ways to shut down or reboot the RPC III 498. It is important to remember that the RPC III 498 is a computer, just like any other. It should not be simply powered off without attempting to shut down the 498 gracefully. The RPC III 498 can recover from a power off done without a graceful shutdown, and sometimes this is necessary. However, this should be the last resort when the following two ways of shutting down the 498 do not work.

There is a difference between a shutdown and a reboot of the 498. A shutdown will leave the 498 in a state where it is ready to be powered off. A reboot will bring the system down and then immediately back up. A shutdown should be used when manipulating any hardware in the 498. A reboot is used when something has changed in the software so that a reboot is needed to make it take effect.

The first way to shutdown or reboot the RPC III 498 is by using the host computer (VMS or Windows NT) to run ASCSHUTDOWN or ASCREBOOT (which are RPC III application programs). These programs will work as long as the 498 is operating properly. If the RPC III portion of the 498 is not operating properly (as an example, when the LCD panel does not display the "Unconfigured" message but "Telnet" to the 498 works), the "bypass" option can be entered on the command line. The command line would be:

      $ ASCSHUTDOWN node_name bypass

Where:

     node_name	is the node name of the RPC III 498.

     bypass	is an option that can only be entered on the command line.  There is no
		prompt for it when these programs are run interactively. 

First try ASCSHUTDOWN and ASCREBOOT without the bypass option. This will reveal if HOSTEXEC (an RPC III application program) and the RPC III 498 application are working together properly.

The second way to shut down or reboot the RPC III 498 is by connecting a terminal to the 498's console port. Refer to the procedure in Section 4.1, "Attaching an ASCII Terminal to the Console Port," for instructions on how to do this. Once the terminal is connected, shutting down or rebooting the 498 is simply a matter of logging into the 498 and executing the "init 0" or "init 5" command.

NOTE
The "init 0" command is the same command that ASCSHUTDOWN executes.
The "init 5" command is the same command that ASCREBOOT executes.

---

For example, to reboot the RPC III 498, log into the "root" account and enter the "init 5" command:

    Console Login: root
    Password: tunafish

    SYSTEM V/68 Release R3V8 Version 960514 M68030

    ***
     erase = #  kill = @  intr = DEL  quit = ^|
    ***

    demo# init 5

This should reboot the 498 and bring it back up. The prompt may be only a "#," instead of the node name followed by the "#," as is shown in this example.
