Echelon SmartServer 2.2 Hardware - Manual (Page 34)

Using the SmartServer LEDs
The SmartServer has a number of LEDs that provide status information. The following figure and
table display and describes these LEDs.
Power/Wink Lights when the SmartServer has power. When the SmartServer receives a
L
ON W ORKS wink command, this LED blinks on and off 5 times. When the
SmartServer’s applications are not running, this LED blinks rapidly.
Service Indicates the state of the LonTalk interface in the SmartServer. This LED
is normally off. Blinking indicates the interface is in the unconfigured
state. This LED will remain lit when the SmartServer is in Security Access
Mode.
Meter The SmartServer has two Meter LEDs, which are labeled 1 and 2. The
Meter1 and Meter2 LEDs light when a pulse is received on the Meter1 and
Meter2 inputs, respectively.
Input The SmartServer has two Input LEDs, which are labeled 1 and 2. The
Input 1 and Input 2 LEDs light when an ON value is received on the Digital
Input 1 and Digital Input 2 inputs, respectively.
The LEDs respond appropriately when the Invert option is selected. For
example, if an open circuit is interpreted as ON, then the LED will light
when the circuit is open and vice versa. The digital input requires a
minimum voltage differential of 3.4V.
Output The SmartServer has two Output LEDs, which are labeled 1 and 2. The
Output 1 and Output 2 LEDs light when power is applied to the Digital
Output 1 and Digital Output 2 outputs, respectively. An Output LED lights
when the relay contacts are closed, and it is off when the relay contacts are
open.
LAN Link Lights when an Ethernet connection has been established.
LAN ACT Lights when there is activity on the Ethernet connection.
LAN 100 Lights when the Ethernet connection is operating at 100 Mbps. The power
line models always operate at 10 Mbps.
LON Connect Lights when the SmartServer is being used as a remote network interface
(RNI) or an IP-852 router.
