Below are cable specifications for the PCI FDDI Dual Attach
adapter. Product safety and/or regulatory conformance may depend
upon observance of the following information. A and B Port Connections The A and B ports on the adapter require one (SAS) or two
(DAS) standard 62.5/125 multimode fibre optic cable(s) with an SC-Duplex
connector. These cables are not provided and must be furnished by
the customer. For existing installations that use cables with MIC (Media
Interface Connector) connectors, SC to MIC cable adapter cables
must be ordered by specifying "Option 001".  | | | |  | WARNING! Never look directly into an optical fiber port. While
not used or supported by this adapter, some fiber optic equipment
can emit laser light that can injure your eyes. Always assume the
cable is connected to a light source. | | | | |
Optical Bypass Relay Connection The Optical Bypass Relay (OBR) connector allows the OBR device
to maintain integrity of the dual FDDI rings if the adapter fails
or if system power is removed. The OBR connector is an RJ-12 modular
jack connector. The pin assignments (counting from right to left,
with pin 1 in the rightmost position) are described in the list
below. | | | | | WARNING! Do not insert telecommunications cabling into the
optical bypass relay connector. | | | | |
OBR RJ-12 Connector Pin Assignments | Pin 1, 2: Relay drive +5.0 V dc | | Pin 3, 4: Bypass enable | | Pin 5: Bypass present | | Pin 6: Return grounded internally |
