POWER-ON LED Test

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.

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.
