* 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 Chapter 9, "Software Upgrade, Maintenance, and Trouble Clearing").
‡ If the 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.
When power is supplied, the SLC ConnectReach system performs a self-test. The
results of the test are indicated through illuminating a combination of light-emitting
diodes (LEDs) located on the front of the unit. The green STATUS LED indicator
lights (only the STATUS LED indicator) when the unit passes all tests and the T1
lines are properly operating.
