2.3.1 CPE030/CRE030 and CPE040/CRE040
2.3.1.1 Serial Ports CPE030/CRE030 & CPE040/CRE040
Each CPU has three independent, on-board serial ports, accessed by
connectors on the front of the module. COM1 and COM2 provide serial
interfaces to external devices; either can be used for firmware upgrades. The
third serial port is a dedicated Ethernet Station Manager port. For serial port pin
assignments, electrical isolation and details on serial communications, refer to
Chapter 5.
2.3.1.2 Ethernet Ports CPE030/CRE030 & CPE040/CRE040
Two RJ45 ports support Ethernet communications. Refer to RX7i Embedded
Ethernet Interface for details.
2.3.1.3 Indicators CPE030/CRE030 & CPE040/CRE040
Seven CPU LEDs indicate the operating status of various CPU functions.
Two Comm LEDs indicate activity on COM1 and COM2.
LED State
On Blinking Off
CPU Operating State
CPU OK On Green CPU has passed its power-up diagnostics and is
functioning properly.
Off CPU problem. RUN and OUTPUTS ENABLED LEDs
may be blinking in an error code pattern, which
can be used by technical support for diagnostics.
This condition and any error codes should be
reported to your technical support representative.
Blinking Green
Other LEDs off
CPU in Stop/Halt state; possible watchdog timer
fault. Refer to the fault tables. If PME cannot
connect, cycle power with battery attached and
refer to fault tables.
CPU OK Blinking in
unison
CPU is in boot mode and is waiting for a firmware
update through a serial port. RUN
OUTS ENA
RUN On Green CPU is in RUN Mode.
Off CPU is in STOP Mode.
OUTS ENA On Green Output scan is enabled.
Off Output scan is disabled.
I/O FORCE On Yellow Override is active on a bit reference
(Not used by CRE030 or CRE040.)
BATTERY On Red Battery has failed or is not attached.
SYS FLT On Red CPU is in Stop/Faulted mode because a fatal fault
has occurred.
C1 (COM1) Blinking Green Signals activity on corresponding serial port.
C2 (COM2)
2.3.1.4 Error Checking and Correction, IC698CRE030 and IC698CRE040
Redundancy CPUs are shipped with error checking and correction (ECC) enabled. Enabling ECC
results in slightly slower system performance, primarily during power-up, because it uses an extra
eight bits that must be initialized. If you upgrade the firmware on a non-redundancy CPU model to
support redundancy, you must set the ECC jumper to the enabled state as described in the
installation instructions provided with the upgrade kit.
For details on ECC, refer to the PACSystems Hot Standby CPU Redundancy User Manual, GFK-2308.
Note: Multiple Recoverable Memory Error faults may be generated when a single-bit ECC error is
detected. When a single-bit ECC error is detected, the value presented to the microprocessor
is corrected. However, the value stored in RAM is not corrected until the next time the
microprocessor writes to that RAM location.
