POWER-ON LED TEST
Every time power is newly applied to the OmniHawk™ the LEDs will flash
through all possible colors to give the user the assurance that other diag-
nostic information may be correctly interpreted. The LEDs will flash all yel-
low, then either green or red. After that, the LED test is over and the LEDs
will illuminate according to the mode (as set by the switches) and the cur-
rent media connections.
SELF TEST / MEDIA TEST
The self test / media test ensures that the OmniHawk™ is fully operational.
Testing occurs when the switches both set to the DOWN position. The bot-
tom two LEDs will both illuminate yellow indicating that power is on and that
the unit is in the test mode. The testing checks both the data passing capa-
bility of the OmniHawk™ and the physical continuity of the media. For both
fiber optic and copper media test data is looped back to the OmniHawk™.
When a looped back fiber cable is connected from the transmit (TX) to the
receive (RX) fiber optic connectors, the fiber optic ready LED lights green.
When a CAT-5 patch cable is connected from the OmniHawk™ to an un-
used lobe of a hub, the copper ready LED lights green. If good connections
are made and the corresponding LED does not illuminate, then the media is
broken. This CAT-5 cable used in this test may be inserted into an operat-
ing hub since the OmniHawk™ will not assert phantom current during the
test mode (and consequently will not enter the network).
INSTALLATION TEST
The OmniHawk™ tests for proper installation and lights the power / error
LED red if a wrong connection is made. This check will only be made when
the connecting devices are stations and/or active hubs. Among active de-
vices, there are initiators and echoers. An initiator is a device that either
sends phantom current or the fiber optic insertion key. An echoer is a de-
vice that receives phantom current or the fiber optic insertion key.
The OmniHawk™ installation test feature warns the installer that an initiator
has been connected to both the fiber optic interface and to the copper inter-
face. Since it doesn’t make sense to connect two ring out (RO) trunk lines
together, the power / error LED warns of this condition by lighting red.
5
To test the integrity of copper patch cables and any intervening baluns con-
nect the OmniHawk™ to an unused lobe of any powered hub. If the cable is
unbroken, the copper ready LED will light green. If the cable is broken, the
LED will be off.
Note that the power / error LED and the test mode LED will both be yellow.
NOTE: TURN OFF THE SELF TEST / MEDIA TEST MODE TO RETURN
TO NORMAL OPERATIONAL MODES.
