2 Installation INSTALLATION CONSIDERATIONS Location and Space The DNI-3 panel mounts flush into both unequal-flange and equal-flange (EIA or WECO) 23" (58.4 cm) network bays. The primary limiting factor of a DNI-3 rack configuration is the number of cables a network bay can accommodate. (The DNI can accommodate 1280 coax cables.) NOTE Telect recommends a maximum of 14 DNI-3 panels per bay, regardless of bay capacity, for easy access and adequate room for cable routing. Here are the DNI-3 spa
