* If the self-test indicates that no power is available to the SLC ConnectReach system, first verify that the AC power cord is
plugged into a functional AC outlet or that the DC power cord is plugged into a functional DC power source. If the power source
is verified to be functional, replace the power cord.
† If the system image check sum fails, you must connect a modem to the RS-232 port and download a new system image (refer
to "Upgrading the SLC ConnectReach System with New Software" located in this chapter).
‡ If the nonvolatile random access memory (NVRAM) check sum fails, it is because some part of the stored configuration has
become corrupted. Since it is not possible to determine which part of the data is corrupted, you should completely reconfigure
the SLC ConnectReach system, save the new configuration, reboot, and observe the self-test LEDs again.
§ Nonrecoverable errors indicate a SLC ConnectReach system hardware failure. You must replace the failed SLC
ConnectReach system with a new unit. After installing the new unit, you must configure the replacement with the same
configuration settings as the original unit.
