Step 2
Connect the Backup Battery
With the cover removed from the JO-PC1 (see
“Removing and Replacing the Cover,”
page 6), locate the red and
black wires coming from the NiMH backup battery, with 2-position connector plug. Insert the plug into the
battery connector on the base board (below option slot 2 area), as shown in
Figure 8

The connector is keyed—you cannot insert it incorrectly. The red (positive) connection should be the furthest
from the two 30-pin option board connectors. For more battery details, see
Apply Power
Apply power to the JO-PC1 by sliding the 20-pin connector into the JO-34 I/O module.Check the Status LEDs
When power is applied, the green LED labeled “STATUS” will light. This indicates that the system is OK and
that power is applied. Once the JO-PC1 boots, the yellow “BEAT” (heartbeat) LED will begin blinking, with a
typical rate of about 1 Hz. Blinking should begin within 30 seconds after power is applied.
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 Systems Engineering for technical assistance. See also the
