Procedure for
recovery from loss
of system image
9-32 Issue 4 June 2002
If a catastrophic failure causes the SLC ConnectReach system to lose its system
image, the SLC ConnectReach system boots from the software in the protected
boot area of memory. In protected boot mode, you can download new software by
means of the RS-232 port. After the download is complete, the SLC
ConnectReach system automatically restarts in normal mode. For information
about downloading software by means of the RS-232 port, refer to the sections
entitled "Software upgrade from a remote computer" and "Software upgrade from
a local computer", located earlier in this chapter.
After downloading new software, you should verify that the unit's configuration
settings are intact. If the configuration stored in NVRAM has been lost, you must
reconfigure the unit as if it were a new installation unless you have archived a
copy of the latest configuration settings. Maintaining current archive copies of the
configuration settings will facilitate the process of reconfiguration. In the event of
catastrophic failure, you can download the archived configuration rather than
reenter it from scratch. Refer to the section entitled "Using the Archive Command
to Upload/Download Configuration Settings", located earlier in this chapter, for
information on the Archive command.
It is recommended that you keep an up-to-date record of the SLC ConnectReach
system's configuration settings. You can keep a record in any or all of the
following ways:
Keep an updated copy of the Preinstallation Worksheet that records all the
3
configuration information gathered at the time of the initial installation. If
you change the configuration later, update the worksheet accordingly.
Print a configuration report using the Show command in the Config
3
submenu. If you change the configuration later, print a new report and save
it in either electronic or hard copy form.
Use the Archive command in the Main Menu to upload a copy of the
3
current configuration to a local or remote computer. If you change the
configuration later, upload a new copy of the configuration.
