SCS100/200/400 User Guide 7: Troubleshooting Boot Prompt Commands If the Boot> prompt appears on the serial console instead of the Local> prompt, one of two things may be wrong. Either the SCS does not have enough information to boot, or the network or flash reloading procedure has failed. If pressing Enter does not display a prompt, press any other key. The Boot> prompt should appear. If the SCS does not have enough information to boot, or the network or flash reloading procedure has failed, it prints a message to the console and waits ten seconds for serial port activity. If the SCS detects serial port activity, it continues booting provided the flash is good. However, if the user presses a key during that time period, the SCS displays the Boot> prompt. Note: If you see the message "Will attempt another download in x minutes," press any key for the Boot> prompt. You can enter a series of commands called Boot Configuration Program (BCP) commands at the Boot> prompt to configure the SCS. These commands are a subset of the entire SCS command set. For example, a typical TCP/IP configuration might use the following commands: BCP Command Examples Boot> SET SERVER IPADDRESS 192.0.1.229 Boot> SET SERVER SOFTWARE /tftpboot/SCS200.SYS Boot> SET SERVER LOADHOST 192.0.1.188 Boot> SET SERVER SECONDARY 192.0.1.22 Boot> FLASH % Initialization begins in 5 seconds..... These commands set the SCS's address, the software loadfile, and the loadhost's IP address (as well as that of a backup loadhost). The SCS then reboots using the Flash command and attempts to load the file firmware file from the host at 192.0.1.188. Flash This command forces the SCS to download new operational code and reload it into Flash ROM. This is necessary when a new version of software is released and you wish to upgrade your unit. If the SCS cannot download the file, the code in Flash ROM is still usable. Flush NVR This command is used to restore the SCS's non-volatile RAM to its factory default settings. It resets everything that is configurable on the SCS, including the unit's IP address. Help Displays a one-page summary of available commands and what they do. 7-4

7: Troubleshooting
Boot Prompt Commands
If the
Boot>
prompt appears on the serial console instead of the
Local>
prompt, one of
two things may be wrong. Either the SCS does not have enough information to boot, or
the network or flash reloading procedure has failed. If pressing
Enter
does not display a
prompt, press any other key. The
Boot>
prompt should appear.
If the SCS does not have enough information to boot, or the network or flash reloading
procedure has failed, it prints a message to the console and waits ten seconds for serial
port activity. If the SCS detects serial port activity, it continues booting provided the flash
is good. However, if the user presses a key during that time period, the SCS displays the
Boot>
prompt.
Note:
If you see the message "Will attempt another download in x minutes,"
press any key for the
Boot>
prompt.
You can enter a series of commands called Boot Configuration Program (BCP)
commands at the
Boot>
prompt to configure the SCS. These commands are a subset of
the entire SCS command set. For example, a typical TCP/IP configuration might use the
following commands:
BCP Command Examples
Boot> SET SERVER IPADDRESS 192.0.1.229
Boot> SET SERVER SOFTWARE /tftpboot/SCS200.SYS
Boot> SET SERVER LOADHOST 192.0.1.188
Boot> SET SERVER SECONDARY 192.0.1.22
Boot> FLASH
% Initialization begins in 5 seconds
.....
These commands set the SCS's address, the software loadfile, and the loadhost's IP
address (as well as that of a backup loadhost). The SCS then reboots using the
Flash
command and attempts to load the file firmware file from the host at 192.0.1.188.
Flash
This command forces the SCS to download new operational code and reload it into Flash
ROM. This is necessary when a new version of software is released and you wish to
upgrade your unit. If the SCS cannot download the file, the code in Flash ROM is still
usable.
Flush NVR
This command is used to restore the SCS's non-volatile RAM to its factory default
settings. It resets everything that is configurable on the SCS, including the unit's IP
address.
