READ THE FOLLOWING   SAFETY INFORMATION BEFORE INSTALLING OR OPERATING   THESE ADAPTERS.   The Class 1 laser transceivers use an optical feedback loop to maintain Class 1 operation limits. This   control loop eliminates the need for maintenance checks or adjustments. The output is factory set, and   does not allow any user adjustment. Class 1 laser transceivers comply with the following safety   standards:   • • • 21 CFR 1040.10 and 1040.11 U.S. Department of Health and Human Services (FDA).   IEC Publication 825 (International Electrotechnical Commission).   CENELEC EN 60825 (European Committee for Electrotechnical Standardization).   When operating within their performance limitations, laser transceiver output meets the Class 1   accessible emission limit of all three standards. Class 1 levels of laser radiation are not considered   hazardous.   SAFETY INFORMATION   CLASS 1 LASER TRANSCEIVERS   LASER RADIATION AND CONNECTORS   When the connector is in place, all laser radiation remains within the fiber. The maximum amount of   radiant power exiting the fiber (under normal conditions) is -12.6 dBm or 55 x 10-6 watts.   Removing the optical connector from the transceiver allows laser radiation to emit directly from the   optical port. The maximum radiance from the optical port (under worst case conditions) is   0.8 W cm-2 or 8 x 103 W m2 sr-1.   Do not use optical instruments to view the laser output. The use of optical instruments to view   laser output increases eye hazard. When viewing the output optical port, power must be   removed from the network adapter.   Download from Www.Somanuals.com.

When using fiber optic cable, use either the   DELFX-UI or the DELF3-UI. The DELFX-UI is used for multimode   fiber cable, and the DELF3-UI is used for single mode fiber cable. Refer   to Appendix B for details on which FEPIM to use with the appropriate   fiber optic cable. To connect to the network using fiber optic cable, refer   to Section 2.4.1. When using twisted pair cabling, use the DELTX-UI. To   connect to the network using twisted pair cable, refer to Section 2.4.2.   2-8   DELHE-UA User’s Guide   Download from Www.Somanuals.com. All Manuals Search And Download.   Connecting to the Network   2.4.1   Connecting a Fiber Optic Segment to the FEPIM   DIGITAL offers fiber optic cables that use SC style connectors which are   keyed to ensure proper crossover of the transmit and receive fibers.   An odd number of crossovers (preferably one) must be   maintained between like devices so that the transmit port of   one device is connected to the receive port of the other device   and vice versa.   If the fiber optic cable being used has SC style connectors that   do not resemble MIC style connectors, or has SC connectors   on one end and a different type on the other, such as ST   connectors, ensure that the proper crossover occurs.   1. Remove the protective covers from the fiber optic ports and from the   ends of the connectors.   Leave the protective covers in place when the connectors are   not in use to prevent contamination.   Certain FEPIMs use Class 1 lasers. Do not use optical   instruments to view the laser output. The use of optical   instruments to view laser output increases eye hazard. When   viewing the output optical port, power must be removed from   the network adapter.   DELHE-UA User’s Guide   2-9   Download from Www.Somanuals.com. All Manuals Search And Download.   Chapter 2: Installation   Do not touch the ends of the fiber optic strands, and do not let   the ends come in contact with dust, dirt, or other contaminants.   Contamination of the ends causes problems in data   transmissions. If the ends become contaminated, blow the   surfaces clean with a canned duster. A fiber port cleaning swab   saturated with optical-grade isopropyl alcohol may also be   used to clean the ends.   ! 2. Insert one end of the SC connector into the FEPIM.   3. At the other end of the fiber optic cable, attach the SC connector to the   other device.   4. Verify that a link exists by checking that the port receive LED is ON   (flashing amber, blinking green, or solid green). If the receive LED is   OFF and the transmit LED is not blinking amber, perform the   following steps until it is ON:   a. Check that the power is turned on for the device at the other end   of the link.   b. Verify proper crossover of fiber strands between the port on the   DELHE-UA and the fiber optic device at the other end of the fiber   optic link segment.   c. Verify that the fiber connection meets the dB loss specifications   outlined in Appendix B.   If a link has not been established, refer to Chapter 3, LANVIEW LEDs,   before contacting a DIGITAL representative.   2.4.2   Connecting a Twisted Pair Segment   to the DELTX-UI   A DELTX-UI has an internal crossover switch. When connecting a   workstation, use a straight-through cable and set the FEPIM crossover   switch shown in Figure 2-5 to the crossed over position marked with X.   When connecting networking devices, such as another bridge, repeater, or   router, use a straight-through cable and set the FEPIM crossover switch   shown in Figure 2-5 to the straight-through position, marked with =.   2-10   DELHE-UA User’s Guide   Download from Www.Somanuals.com.
