Working inside the Digi CM Unit
NOTICE: Do not attempt to service the Digi CM unit yourself, except when following the instructions
from Technical Support personnel. In such a case, first perform the following actions:
▪ Turn off the Digi CM unit.
▪ 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 the Digi CM unit, 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.
Remplacer la batterie
Une pile bouton maintient les informations de date et d'heure. Si vous devez réinitialiser à plusieurs
reprises les informations d'heure et de date après avoir allumé l'unité Digi CM, remplacez la
batterie.
ATTENTION! Une nouvelle batterie peut exploser si elle est mal installée. Remplace le Pile 3 volts
CR2032 uniquement du même type ou d'un type équivalent recommandé par le
fabricant de la batterie. Jetez les batteries usagées en fonction de la batterie
instruction du fabricant.
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
that may damage over-current protection devices and supply wiring.
▪ Maintain reliable earthing for rack-mounting equipment, especially for supply connections.
