CONNECTORS, SWITCHES & INDICATORS CONNECTORS The OmniHawk™ has three interface connectors: a fiber optic transmitter and receiver pair, an RJ45 jack, and a DB9 male connector. The DB9 connector and the chassis are designed to attach directly to the rear of a workstation network interface card. The jack screws ensure a solid connection.
C. Hub Ring Out (RJ45) to distant hub Ring In (RJ45) Application C shows the Ring Out of one hub connected to the Ring In of another hub via a pair of OmniHawk™ converters. Note that the cable from the second OmniHawk™ to the Ring In is a crossed cable. D.
The operational modes are: 1. AUTOMATIC SENSING 2. UTP/STP —> RO or STATION 3. UTP/STP —> RI or LOBE The power / error LED turns red when an attachment error occurs. An error can only occur when attaching to active devices (devices which signal for insertion with phantom current or the fiber optic key).
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.
RUN-TIME ACTIVITY & ERROR MONITORING During normal operation the fiber optic and copper ready LEDs provide continuous diagnostic information. These LEDs detect and display token ring activity. The insert status LED informs the user of the insert status of the fiber optic and copper media.
