CNRACKX Indicators
There are 22 LED indicators on the front panel of the CNRACKX. The other two
LEDs on the rear are part of the CNXCPU:
PWR
These two LEDs (one on the front panel and one on the CNXCPU) illuminate when
the CNRACKX receives power from the CNPWS-75 External Power Supply (sold
separately).
NET
These two LEDs (one on the front panel and one on the CNXCPU) illuminate when
the CNXCPU is processing data or communicating with system hardware. Examples
are a button pressed at the local or a network panel, data being sent out of either
serial port, or a permanent memory image being created.
ERR
This LED illuminates when one or more error conditions are detected by the
CNXCPU. This may be the result of hardware or software failure, hardware
incompatibility with software definitions, or a programming error. To read the error
message(s), press the MSG (from the Default Info Menu) and MENU DOWN
buttons to examine the error(s). The LED extinguishes after the last message has
been read.
NOTE:
The next four LEDs are active only if the optional CNXENET Expansion
Card is installed and the CNRACKX is connected to a LAN.
RXD (LAN)
This LED illuminates during reception of Ethernet data by the CPU slot.
TXD (LAN)
This LED illuminates during transmission of Ethernet data from the CPU slot.
LNK (LAN)
This LED illuminates when there are attachments to the Ethernet network.
ERR (LAN)
This LED illuminates when an Ethernet protocol error is detected.
INTERFACE CONTROL CARD SLOT (1 – 15)
These LEDs illuminate when a CNX expansion card is present in a respective slot.
CNRACKX Buttons
Two buttons are provided on the front panel of the CNRACKX. Refer to the
description of each below:
HW-R
Depression of this button initiates physical reset of the system.
SW-R
The SW-R button is used to initiate a restart of the SIMPL program. Holding the
button while the unit is starting (or restarting), sets the CNRACKX to a default mode
where the communications baud rate is set to 9600 and no program is executed.
