Interpret the Module Status Indicators Chapter 7
Table 28 - Module Status Indicator
State Status Description Recommended Action
Off No power No power is applied to the power connector.
No power is applied to the input power connector or severe
input power overvoltage.
(1)
Apply power to this connector.
Apply input power that is within specification to the
module.
(2)
Solid green Normal operation The module is operating normally. None.
Solid red Unrecoverable fault The module detected an unrecoverable fault. Cycle power to the module. If problem persists, replace the
module.
Flashing red and
green
Module is unconfigured Module needs commissioning due to missing, incomplete,
or incorrect configuration.
Reconfigure the module. For additional information, inspect
Network Status indicator.
Device in self-test The module is performing its power-cycle diagnostic tests. Wait for the module to complete its power-cycle diagnostics.
Flashing green Idle Idle, waiting for connection from scanner. Establish connection.
Flashing red Recoverable fault The module has detected a recoverable fault. Cycle power to the module or reset the module.
User-initiated firmware update in
progress
User-initiated firmware update is in progress. Wait for firmware update to complete.
(1) This description applies to only the 1732ES modules.
(2) This recommended action applies to only the 1732ES modules.
Table 29 - Network Status Indicator
State Status Description Recommended Action
Off Module not online The module does not have an IP address. Verify that your network is working properly.
Flashing green Module online with no connections in
established state
The module has acquired an IP address, but no connections
are established.
Verify your network and module configuration.
Solid green Module online with connections in
established state
The module is operating normally. None.
Flashing red One or more I/O connections in timed-
out state
The module detected a recoverable network fault. Verify your network and module configuration.
User-initiated firmware update User-initiated firmware update is in progress. Wait for firmware update to complete.
Solid red Critical link failure The module detected an error that prevents it from
communicating on the network, such as duplicate IP
address has been detected.
Cycle power to the module. Check network IP addressing.
Flashing red
and green
Self-test The module is performing its power-cycle diagnostic test. Wait for the module to complete its power-cycle diagnostics.
Waiting for TUNID
(1)
The module has received the proposed UNID and is waiting
for the TUNID.
(2)
None.
(3)
(1) This status applies to only the 1732ES modules.
(2) This description applies to only the 1732ES modules.
(3) This recommended action applies to only the 1732ES modules.
Table 30 - Network Activity Indicators (link 1 and link2)
State Status Recommended Action
Off No link is established. Establish link.
Flashing Green Transmit or receive activity. None.
Steady Green Link is established None.
Table 31 - Test Output Status Indicator (only 1791ES Modules)
State Status Description Recommended Action
Off Test output off The test output is off or the channel is configured for not
used.
Turn on the test output or reconfigure the channel, if desired.
Solid yellow Output on Output is on. None.
Solid red Fault detected A fault in the external wiring or input circuit detected. Check field wiring. If no problem found, replace module.
For outputs that are configured for muting, this could
indicate undercurrent or burned-out lamp.
