IEN 2000
The IEN 2000 is a two-slot chassis capable of running multiple Hypercom port processors.
The IEN 2000 chassis is typically used at a branch office providing support for two port
processors or can be bus connected with up to three additional IEN 2000 chassis for four,
six, or eight-slot configurations. This allows a user to start small and expand their IEN
configuration as new requirements develop. Port processors used by the IEN 2000 chassis
are the same as those used by the IEN 3000, IEN 4000 and IEN 5000, allowing a user to
move to even larger configurations if required.
The IEN 2000 contains a single 110/220VAC auto sensing power supply.
Front Panel
The front panel of the IEN 2000 chassis contains the status indicator nomenclature for each
of the ports. Refer to Chapter 3, Port Processors for more information about the status
display indicators. Figure 2-1 illustrates the front panel of the IEN 2000 chassis.

SBUS
TX The Standard Bus Transmit is an LED indicator that indicates the unit is transmitting data to
the standard packet bus.
HiBUS
ACT The High Speed Bus Activity 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.
SBUS
RX The Standard Bus Receive is an LED indicator that indicates the unit is receiving data from
the standard packet bus.
USER
PORTS The User Ports is an LED indicator that indicates 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.
STAT The Status (STAT) is a seven-segment LED display that provides a current operational status
of the port processor.
