3.1 TESTS

Each node of the Dual Node Module is tested through firmware (in hardware) and software
checks. Firmware tests built into the node provide two similar means of functionally
checking the unit, whether or not it is connected to the LCN. The first firmware test starts
when power is applied. Pressing the
firmware test.
Software tests start after the node is connected to the system. Loading the node
personality, for example, initiates a software Quality Logic Test (QLT).
Figure 3-1 is a flow diagram showing the relationship of the hardware and software tests.

3.2 TEST PROCEDURES

Each node must have a K2LCN OR K4LCN installed and must have access to a KLCNA
(or CLCN-A) and KLCNB (or CLCN-B) on the RS-485 bus before it can be fully tested.

3.2.1 Power-On Test

Initiate power-on tests by pressing the "1" side of the power switch. Note that the red
LEDs on the boards light for a few seconds (less than two minutes); then they should turn
off and the green LEDs should turn on as the node passes its Quality Logic Tests. When
the tests are complete, each node's alphanumeric display (on the K2LCN or K4LCN
board) indicates its node address. Ensure that the expected node address is displayed.
Check the power supply POWER STATUS LEDs. Be sure that the green LED is on and
that the red LED is off. Check the red FAN ALARM LED to ensure that it is not on or
blinking.

3.2.2 Reset Test

If this is not a History Module, press the
momentarily as above, and then should go out when the green LEDs come on. Recheck
the power supply, board, and fan LEDs as above. Note that each alphanumeric display
indicates its node address.
If any of the above conditions does not pass, refer to subsection 3.3, Troubleshooting.
* 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 disk drives. For more details,
see subsection 3.2, Troubleshooting , in the History Module Service manual, part of the LCN Service
binder.
