Working Inside the Digi CM

NOTICE: Do not attempt to service the Digi CM yourself, except when following the instructions from Digi Technical Support personnel. In such a case, first perform the following actions:

•Turn off the Digi CM.

•Ground yourself by touching an unpainted metal surface at the back of the equipment before touching anything inside your equipment.

Replacing the Battery

A coin-cell battery maintains date and time information. If you have to repeatedly reset time and date information after turning on your Digi CM, replace the battery.

CAUTION: A new battery can explode if it is incorrectly installed. Replace the 3 Volt CR2032 battery only with the same or equivalent type recommended by the battery manufacturer. Discard used batteries according to the battery manufacturer’s instructions.

Rack Mounting Installation Considerations

For a rack setup with forced air, the device can run 0-55° C with no extra space above or below the device (default design of the Digi CM Rack provides 1/16” = 2mm between devices).

For a rack setup with no forced air, make sure that the air in-between devices does not get warmer than 55°C by the following measures:

•Providing space between the devices, or

•controlling the ambient temperature on the rack.

•Distribute weight evenly in the rack to avoid overloading.

•Check equipment nameplate ratings before connecting to the supply circuit to avoid overloads which may damage over-current protection devices and supply wiring.

•Maintain reliable earthing for rack-mounting equipment, especially for supply connections.
