EXAMPLE: A Single network segment with 40 or fewer rooms/common spaces
WIRING EXAMPLES
The following pages display some examples of various connection scenarios.
LMJA-8125/8300
The LMJA-8xxx can connect to up to two separate segments, and is used for buildings in which there is no more than 120 rooms
(controlled by the LMBC-300 bridge) or common areas (controlled by a panel or zone controller).
POWER UP AND INITIAL CHECKOUT
Ensure power wiring to the LMJA-8xxx is ready—see the “Wiring: Earth Ground and Power” section. Refer to page 10 for the locations
of the power connections.
After mounting and wiring, perform the following:
Step 1: Apply Power
•
Apply power to the LMJA-8xxx by plugging the power into one of the power connections on the LMJA-8xxx. Refer to page 8 for
location of the power connector.
Step 2: Check the Status LEDs
•
When power is applied, the “STATUS” LED is located to the right of the heartbeat (“BEAT”) LED, and is green. This LED provides a
CPU machine status check, and should be lit when the LMJA-8xxx is powered.
If the STATUS LED is not lit while power is applied, contact Wattstopper technical support.
•
Once the LMJA-8xxx boots, the yellow “BEAT” (heartbeat) LED begins blinking. The “BEAT” LED is located to the right of the
Ethernet LEDs, and is yellow. Under normal operation, this LED should blink about once per second. If the heartbeat LED stays on
constantly, does not light, or blinks very fast (more than once per second), contact technical support.
•
If after applying power, the STATUS LED goes out, or if the BEAT LED comes on (steady) and stays lit longer than two minutes,
contact WattStopper Technical Support. See also the “Using Status LEDs” section.
