Replacing the WEB/CP-700
NOTE: Before handling circuit boards, discharge any accumulated static by touching a nearby earth ground. For
details, see “Static Discharge Precautions” on page 7.
To replace a WEB/CP-700 with a new replacement unit, proceed as follows:
Replacing a WEB/CP-700 main controller board.
1. If possible, use the appropriate NiagaraAX software tool to back up the WEB/CP-700’s configuration to your PC.
2. Remove power to the WEB/CP-700, including any external 12V battery. The unit should power down automatically. Wait for
all LEDs to remain off.
3. Remove the front cover. See Removing and Replacing the Cover, page 9.
4. Note positions of all communications and other wiring cables going to the controller. If necessary, label connectors and
accessory modules to avoid mis-connection later, after WEB/CP-700 is replaced.
5. Unplug all Ethernet, serial, LON, modem, and I/O connectors from the controller. Note the position of installed option cards,
if any. You must transfer them to the replacement WEB/CP-700 controller.
6. Remove the controller from its mounting (DIN rail, panel mount tabs, etc).
7. Remove any option cards from the old controller and install them into the replacement WEB/CP-700, if applicable. See
Installing an Option Card, page 12 for more details.
8. Mount the replacement WEB/CP-700 as it was previously, using the same DIN rail location and/or screws.
9. Reconnect the earth ground wire to the WEB/CP-700 grounding lug and any installed accessory modules.
10. Reconnect any Ethernet, serial, modem, and I/O connectors to the WEB/CP-700 board.
11. If using IO modules, and any of your I/O points have voltage, turn the devices back on, or reconnect power to them.
12. Replace the cover. See Removing and Replacing the Cover, page 9
13. Restore power to the unit. It should boot up as a new unit (see Check the Status LED, page 19).
14. Using the WEBsAX platform tools, re-commission the WEB/CP-700, and install the saved station database. For more
details, see the WEBsAX Install and Startup Guide.
