LEDs
The LGE has several LED indicators to show
the status of certain functions. Table 3 on
page 8 explains the Run and Error LED
signals in detail to assist troubleshooting. See
Figure 1 on page 2 for location of LED signals.
Power - indicates power is being supplied to
the module.
CMnet transmit - indicates that the LGE is
transmitting data over the CMnet.
CMnet receive -indicates that the LGE is
receiving data from the CMnet.
Console transmit - indicates that the Console
Port is transmitting data.
Console receive - indicates that the Console
Port is receiving data.
Link- indicates communication through the
Ethernet port.
Lan - blinks to indicate network activity.
Protection
The LGE is protected by internal solid state
Polyswitches on the incoming power and
network lines. These Polyswitches are not
replaceable and will reset themselves if the
condition that caused the fault returns to
normal.
Production Date
To determine when a module was
manufactured, check the Module Status
report in SuperVision. Refer to the
SuperVision
User’s Guide
for more information about the
Module Status report.
A sticker on the back of the module also
shows the date the module was
manufactured. The first three characters on
the sticker indicate the type of module. The
next three characters show the year, month,
and week of manufacture. (The month digit is
in hexadecimal.)
