Using your Eicon 1550/1551 40
Indicator Lights
The following diagram describes the behavior of the indicator lights on the
Eicon 1550/1551. Note that the ISDN lights apply only to the Eicon 1551.
Console Port Light
ON or Flashing:
Data is being sent or received
via the Console port.
Off: The Console port serial
cable is not connected or data
is not being sent or received
via the Console port.
Ethernet Lights
ON: The Ethernet cable is
connected properly.
OFF: The Ethernet cable is not
connected, or the wrong cable
is connected (straight-through
or crossover).
FLASHING: Data is being sent
or received via the Ethernet
cable.
E4 Flashing red: An Ethernet
collision has occurred. If
infrequent, this is a normal
occurrence that will correct
itself.
VHSI Light
If you are using X.25 :
ON: The X.25 layer is ready.
FLASHING: The X.25 layer
is not ready.
OFF: The X.25 port is
closed or the cable is
disconnected.
If you are using PPP :
ON: The PPP layer is
connected.
FLASHING: The PPP layer
is trying to connect to a
remote site.
OFF: The PPP layer is
closed or the cable is
disconnected.
If you are using Frame Relay :
ON: The Frame Relay layer
is connected.
FLASHING: The Frame
Relay layer is opening.
OFF: The Frame Relay layer
is closed or the cable is
disconnected.
Power Light
Solid green: Power adapter
is properly connected.
Flashing red only: Device
firmware is being upgraded.
Do not reset or unplug the
power adapter.
Flashing red/green: Device
is in boot mode. If you are
not upgrading firmware
while in boot mode, press
the Reset button once to
return the device to normal.
If you are upgrading
firmware while in boot mode,
do not press Reset for at
least one minute after
transferring the firmware to
the device.
Rapidly flashing red: A fault
has occurred. Press the
reset button once to return
to normal.
ISDN Light
International Firmware:
OFF: D turns on to indicate a properly configured
line. However, when the line is idle, many networks
automatically disconnect the D-channel (turning
off the D light) to conserve power.
SOLID: D will turn on just before the B light when
the Eicon 1551 makes a call. When solid, the D
light indicates a properly configured ISDN line.
B Lights
OFF: No call activity
on the B-channel.
FLASHING: A call
is being established
on the B-channel.
SOLID: A call is
connected on the
B-channel.
Link Light
OFF: The ISDN physical interface is not
synchronized, or the ISDN cable is improperly
connected.
FLASHING: The ISDN physical interface is
synchronizing.
SOLID: The ISDN physical interface is active.
Note: Flashing stops when synchronization is
complete. Continuous flashing indicates an
error. Make sure that the line is plugged in
properly and that you are using the correct
interface (S/T or U). For S/T with an NT1, make
sure your ISDN line is terminated (see your
ISDN provider for more details).
