or upgrading device firmware via a Terminal program (see Using
HyperTerminal in Chapter 4 for instructions).
LED Indicators
Figure 3-1 Indicator LEDs
The ETC2002 has two yellow device status LEDs and ten green network
status LEDs that show the present device status and activity on
communication ports.
The flashing yellow CPU LED indicates the device status as follows:
• The CPU LED flashing for one second with a one-
second pause indicates that the device is in the
operational state and is functioning normally.
Depending on the position of the PROG-RUN switch,
the COM3 service port is available for communications
via a Terminal program or for master communications.
• The CPU LED flashing briefly 2 times with a one-
second pause indicates that the device is in service
mode and is not operational.
• The CPU LED flashing briefly 3 times with a one-
second pause indicates that a critical error has
occurred and the device is not operational. Contact
your local distributor for servicing.
The yellow BATTERY LOW LED lights up when the backup battery is near
the end of its operational life and should be replaced.
The network status LEDs indicate activity on communication ports as follow:
• COM1 Ethernet port: the LINK LED lights up when the
port is connected to the local network; the ACTIVITY
LED flashes when the device receives or transmits
data via the Ethernet port.
• COM2 Dial-Up modem port: the DCD (Data Carrier
Detect) LED lights up when a connection between the
ETC2002 and a remote modem is established; the
ACTIVITY LED flashes when the device receives or
transmits data via the modem port.
• COM3, COM4 and COM5 serial ports: the RX and TX
LEDs flash when the device receives or transmits data
via a port.
