For GSM connections, the RediGate 400 uses a standard (also referred to as "mini") SIM card. The steps below show how to install the SIM card:
Step 1:
Remove power and all connectors from the front panel of the RediGate.
Remove the rubber end cap and the five mounting screws from the front faceplate.
Step 2:
Gently slide the RediGate out of its enclosure about 5 inches (127 mm) to expose the SIM card slot. Do not remove the processor entirely from the enclosure.
Step 3:
Fully insert the SIM card into the SIM card slot, with the metal contacts facing down and the angled edge facing out.
Step 4:
Gently slide the RediGate back into its enclosure and carefully replace the five mounting screws to avoid over-tightening.
Replace the rubber end cap and all front panel connectors.
