The Outer Door Grill Plate (Model OD-GP), which is furnished in black, covers an entire row on the outer door of a Siemens Modular (or FireFinder) system cabinet, but has four (4) rows of ventilation louvers on it. Model OD-GP is mounted in front of system-bulk amplifiers, card amplifiers, or other modules that generate heat. Using Model OD-GP will permit airflow across these modules to aid in heat dissipation. One (1) grill plate is included with each order of Model OG-GP.
