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.
Indicator Lights
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.
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.
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.
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.
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).

Note: ISDN lights (B, ISDN,
and Link) are available on
the Eicon 1551 only.
