NetAXS™ NX4S1 Installation Maintenance 8.0 Maintenance Perform the following maintenance on the NetAXS™ enclosure: • Change the CASIL CA1270 lead-acid battery (Honeywell Access Systems part number 3-000066) every two to two and a half years. Caution: Do not connect an uncharged battery to the panel. • Oil the lock once per year. 9.0 Troubleshooting Table 8 Troubleshooting Problems and Solutions Problem Solution The panel powers up, but it does not respond to any communication, cards reads, or input activation. Ensure that the Address DIP switches are set to a value other than zero. Turn off the power (including battery), change the settings, and re-apply the power. No communications exist with the Ethernet port. Only a panel set to be a Gateway (DIP switch 6 = ON) will have communications on the Ethernet port. If you need to use that port to access the panel, turn off the power (including the battery), change the switch setting, and reapply the power. Note that if the panel is normally not a Gateway on a Multidrop communication bus, then the Host RS-485 connection (TB7) should also be disconnected while DIP switch 6 is ON. After completion of the Ethernet session, turn off the power (including the battery), change the switch setting, re-connect the Host RS-485 terminal block, and re-apply the power. The IP address is If you are connecting directly to a computer instead of going through a incorrectly set to router or hub, use a cross-over Ethernet cable. verify the value. The N1000 panels on the Multidrop bus do not report. N1000 panels will not communicate to a NetAXS™ panel that is configured as a Gateway. Replace all of the N1000 panels with NetAXS™, or replace the Gateway panel with an N-485-PCI-2 device. The BAD CRC counter is incrementing every minute. Two or more panels on the Multidrop Bus have the same panel address. Verify that each panel has a unique address setting on DIP switch positions 1-5. 48 www.honeywell.com
