For installations based within the United States, an MGC-100 DC NEBS compliant system is available. The NEBS compliant systems differs in its construction of the frame and the power supply. All else remains the same.

The construction of the MGC-100 is 12 U’s, (1 U = 4.3 cm) which makes it higher by 3 U’s than the original frame of the MGC-100. This design allows for a cushion of air to be present, ensuring safety in case of a heat related problem.

In addition, the power supply is also designed differently by allowing the circulation of cool air, providing a safety tolerance in case of a heat related problems.

Use only shielded LAN cables where the shield is grounded at both ends when connecting to the IO LAN port of the IP+48 on the MGC+ rear panel.
