Replacing the Optional IB4 Board
Procedure
NOTE!
Refer to Figure 5.5, Figure 5.6, or Figure 5.7 for circuit card locations. Refer to Figure 5.11 as this procedure is
performed.
1.
Performing this procedure may activate external alarms. Do one of the following. If possible, disable these alarms. If these
alarms cannot be easily disabled, notify the appropriate personnel to disregard any future alarms associated with this system
while the procedure is being performed.
DANGER!
Performing the next steps exposes service personnel to battery potential. Exercise extreme caution not to
inadvertently contact or have any tool inadvertently contact any energized electrical termination.
2.
Open the distribution cabinet’s front door.
WARNING!
Damage to the circuit card may result if the next step is not followed.
3.
Connect an approved grounding strap to your wrist. Attach the other end to a suitable ground.
4.
Loosen the captive fastener securing the latch mechanism to the front of the NCU. Pull the latch mechanism away from the
NCU (this will retract the latch mechanism located on the bottom of the NCU). This unlocks the NCU from the shelf. Slide
the NCU partially out from the shelf.
5.
Carefully label the connectors plugged into the circuit card. These connectors must be plugged into the same connectors on
the replacement circuit card.
6.
Unplug all connectors plugged into the circuit card.
7.
Remove the circuit card (and shield) from the distribution cabinet by removing the screws securing it to the cabinet. See
Figure 5.11.
8.
Secure the replacement circuit card (and shield) to the distribution cabinet. See Figure 5.11.
9.
Plug all connectors removed from the old circuit card into the same position on the replacement circuit card.
10.
Slide the NCU completely into its mounting position. Push the latch mechanism into the front panel of the NCU, and secure
by tightening the captive fastener. This locks the NCU securely to the shelf.
11.
Remove the grounding wrist strap.
12.
Close the distribution cabinet’s front door.
13.
To verify that the IB4 board is functioning, from the Main Menu on the local display, press the ESC button, then down arrow
and verify the IP address 192.168.100.100 is displayed.
14.
Enable the external alarms, or notify appropriate personnel that this procedure is finished.
15.
Ensure that there are no local or remote alarms active on the system.
