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.

B2

B1

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.

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.

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).

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.

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.

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

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.

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).
