Maintenance

NG Series Gateways need minimal maintenance. If a device fails, it may be due to environmental damage,

or even a blocked wireless connection.

System Time Backup Power Battery

To keep the real-time clock (system time) and radio oscillator running while the gateway does not have

power from the PoE or external power connector, NG Series Industrial Wireless Gateways use a Lithium

coin-sized battery.

The battery should be replaced if the NG Series Industrial Wireless Gateway time keeps resetting to the

same incorrect date and time after power loss.

Install only approved CR2032 Lithium batteries. For details and ordering information, see the NG Series

Industrial Wireless Gateway Datasheet (document 20DD1979).

Clean and Inspect Devices

Use a damp cloth to clean the exterior of NG Series Gateways in potentially hazardous environments.
