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.
