6.1 VISUAL CHECKS
• Check the Module power and signal cables to ensure that they are present and tight.

board retainers are secured.

• Turn the power on by pressing the "1" side of the power switch. After 2 minutes or
less, all red LEDs should be off and all green LEDs should be on, and the alphanumeric
display should indicate the address of the node. If not, check indicators and LEDs in
accordance with subsection 3.2, Test Procedures.

* In the case of the History Module only, if you press the RESET button indiscriminately while
the system is operating, you may cause damage to the data stored on the hard disk. See
subsection 3.2, Troubleshooting , in the History Module Service manual, part of the LCN

When you replace or restart a board or module with an outstanding maintenance
recommendation, be sure to make an SMCC corrective action entry. Otherwise, the system
will not start a recount of errors. See the System Maintenance Guide in the LCN Service
