Back Panel
Control Panel
The control panel consists of an LCD display and a keypad. The control panel enables preliminary
configuration and basic monitoring of ProStream 9100. It is usually used for standalone devices.
For more information, see
Front Panel .
Front Panel LEDs
The four LEDs on the front panel indicate the operational status. There is no difference in LED
functionality whether ProStream 9100 is operating in NMX or standalone control mode. For more
information, see
Figure 1–2 .
Air Inlets
The air inlets are designed to provide maximum air flow. The air flow is critical for maintaining the
correct temperature range. Fans in the front unit draw air in through the front inlets. For details on
cleaning and replacing air filters, see
Air Filter .
CAUTION: Do not obstruct the airflow when mounting the device on the rack. Severe equipment damage
can result when the device cannot properly exhaust the airflow.
Cooling Fans
The ProStream 9100 platform uses a fan tray unit that contains eight 12V fans that control the
temperature during operation. The fans located in the front of the device use air from the front
and exhaust it to the rear of the device. Each fan has a speed control mechanism and the CPC
manages their speed. The Fan Control mechanism triggers the fans to accelerate according to
real environmental measurements to increase Mean Time Between Failures and to lower the
noise level when working in typical environmental conditions.
All fans are mounted on the back side of the front panel to allow quick and easy field replacement
in case of a fan failure. For more information, see
Fan Tray .
Back Panel
The following figure illustrates the back panel of the ProStream 9100 device with an optional
configuration of IOMs. The number and type of mounted IOMs varies according to the needs of
the customer.
