Operators (Ops) Panel
The operators panel (ops panel) contains an enclosure services processor that monitors
and controls the enclosure (see Figure 1-6). The ops panel contains LEDs which show the
status for all modules, an audible alarm that indicates a fault state is present, a
push-button alarm mute switch, and a thumb-wheel enclosure ID address range selector
switch. When the 2 Gb TP9100 is powered on, the audible alarm sounds for one second,
and the power-on LED illuminates.
