IEN 3000
The IEN 3000 chassis is a six-slot chassis capable of running each Hypercom port
processor. The IEN 3000 chassis is typically used at large remote sites that exceed the
capacity or functions supported by the IEN 1000 chassis. As a stand-alone unit, the
IEN 3000 chassis can perform as a powerful multiprotocol router.
The IEN 3000 chassis contains redundant power supplies. Power supplies are available in
110VAC, 220VAC and 48VDC configurations. A single power supply failure results in an
alarm being transmitted to IENView.
Front Panel
The front panel of the IEN 3000 chassis contains the status indicator nomenclature for each
port. Refer to Chapter 3, Port Processors/Modules for more information about status
display indicators. Figure 2-5 illustrates the front panel of the IEN 3000 chassis.

RTS The Request to Send (RTS) is an LED indicator that indicates the unit is transmitting data to the
standard packet bus.
TXD The Transmit Data (TXD) is an LED indicator that indicates the port is transmitting data on the
high speed bus. Older Z80 port processors do not have high speed bus capability. This indicates
low speed bus activity on the Z80 port processor.
RXD The Receive Data (RXD) is an LED indicator that indicates the unit is receiving data from the
standard packet bus
RTS
DCD The Request to Send (RTS) and Data Carrier Detect (DCD) are LED indicators that indicate a
signal from the DCE (modem or printer) to the DTE, indicating it is receiving a carrier signal from
the DCE at the other end of the telephone circuit. The LEDs vary by the type of port processor.
STAT The Status (STAT) is a seven-segment LED display that provides a current operational status.
