SFM Front Panel and LEDs

Table 7-2

describes the SFM front panel and LED displays.

Blank Panels

Blank panels are required to prevent excess dust accumulation, control airflow, and prevent

electromagnetic interference. Blank panels are like line cards but do not have circuit boards or ejector

levers. The same blank panel is used for empty line card and RPM slots.
