SAFETY INFORMATION  
CLASS 1 LASER TRANSCEIVERS  
THE DELHE-UA GIGABIT ETHERNET MODULES USE  
CLASS 1 LASER TRANSCEIVERS. 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.

INSTALLINGFAST ETHERNET (PORT) INTERFACE  
MODULES  
Only qualified personnel should perform installation  
procedures.  
Fast Ethernet (Port) Interface Modules (FEPIMs) must be installed in the  
DELHE-UA before installing the DELHE-UA in the host device. The  
FEPIMs provide connectivity to the network. At least one FEPIM must be  
installed in either port one or port two. To install an FEPIM in the  
DELHE-UA, proceed as follows:  
The DELF3-UI uses 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.  
The FEPIM and the DELHE-UA are sensitive to static  
discharges. Use an antistatic wrist strap and observe all static  
precautions during this procedure. Failure to do so could  
damage the FEPIM or the DELHE-UA.  
!
1. Remove the coverplate from the port slot where the FEPIM will be  
installed.  
To remove the coverplate, refer to Figure 2-1 and proceed as follows:

CONNECTING TO THE NETWORK  
The DELHE-UA can be connected to the network using either fiber optic  
cable or twisted pair cable. The media chosen determines which type of  
FEPIM to be used. 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  
 
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  
 
 
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.
