CNRACKX-DP
CNRACKX-DP System Status Indicators
There are 22 LED indicators on the front panel of the CNRACKX-DP. Four other
LEDs are located on the rear of the CNXCPUs:
PWR
These LEDs (one on the front panel and one on each CNXCPU) illuminate when the
CNRACKX-DP receives power from the CNPWS-75 External Power Supply (sold
separately).
NET
These LEDs (one on the front panel and one on each CNXCPU) illuminate when
either CNXCPU is processing data or communicating with system hardware.
ERR
This LED on the front panel of the CNRACKX-DP illuminates when one or more
error messages are reported by either CNXCPU. These messages 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.
INTERFACE CONTROL CARD SLOT (1 – 13)
These LEDs illuminate when a CNX expansion card is present in a respective slot.
CNRACKX-DP LAN Indicators
These front panel LEDs are active only if optional Ethernet Expansion
Cards are installed into the CNXCPUs and the CNRACKX-DP is connected to a
LAN.
RXD
This LED illuminates during reception of Ethernet data by either processor slot.
TXD
This LED illuminates during transmission of Ethernet data from either processor
slot.
LNK
This LED illuminates when there are attachments to the Ethernet network.
ERR
This LED illuminates when an Ethernet protocol error is detected.
CNRACKX-DP Buttons
Two buttons are provided on the front panel of the CNRACKX-DP. Refer to the
description of each below. For descriptions of the buttons for the LCD Display, refer
to
on the next page.
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 CNRACKX-DP is starting (or restarting), sets the unit to a default
mode, the communications baud rate is set to 9600 and no program is executed.
