F2.2 Status Indicators and Actions
The YFGW410 provides three status indicator LEDs, “RDY”, “SYN”, and “ACTIVE”, on the front
side.
l
Single system
When a single YFGW410 manages the system, only “RDY” is available.
The “SYN” and “ACTIVE” indicator LEDs are always turned off.
Table F2-2 Status Indicator LED List (Single System)
LED Status Device Status
Turned off Powered off
ORANGE Powered on, active
RED blink Not connected to the synchronization connector, or failure
GREEN Normal running
RED Error occurrence
When the LED blinks red, it is assumed that the synchronization connector is not connected. If
the correct terminator is installed, it is assumed there is a loose connection or that an internal er-
ror of the connector has occurred.
When any LED lights red, check the cables and hubs connected to the field network port for the
host system. If an error is detected, recover it. If the F1 port causes link-down, the “RDY” indica-
tor LED lights red. If no error is detected in wiring relation, an error is indicated in gateway status
information described in Section F2.1 Status Information, or an error is indicated in device infor-
mation on the Monitor, it is assumed that a failure occurs in the YFGW410. For details on how to
replace a YFGW410 device, see Section E2.3 Field Wireless Management Station (YFGW410).
l
Redundant system
To manage the system in the YFGW410 redundant configuration, the device status is indicated
using three LEDs.
Table F2-3 Status Indicator LED List (Redundant System)

the YFGW410 redundant configuration.
N/A GREEN blink GREEN or OFF
YFGW410 is in process of synchroniza-
tion.
