Note: The distance from the mounting panel to the front of the ROC827 is 174mm (6.85”). If you mount the ROC827 inside an enclosure and want to connect a cable to the LOI or Ethernet port, ensure adequate clearance for the cable and the enclosure door. For example, a molded RJ-45 CAT 5 cable can increase the clearance requirement for the enclosure by 25mm (1”).
