4.8 Modular Optical Transceiver Installation
The modular optical transceivers are available separately and may or may not be installed in
the DHU depending on the configuration ordered. If the optical transceivers are factory
installed in the DHU, skip this section and proceed to Section 4.9. If the optical transceivers
are not factory installed, use the following procedure to install each transceiver:
1. Slip on an Electro-Static Discharge (ESD) wrist strap and connect the ground wire to an
earth ground source such as the grounding stud on the DHU front panel. Wear the ESD
wrist strap while completing the optical transceiver installation procedure.
Warning: Electronic components can be damaged by static electrical discharge. To prevent
ESD damage, always wear an ESD wrist strap when handling electronic components.
2. Locate the appropriate transceiver socket on the front of the DHU as shown in Figure 19
and remove the port cover from the socket.

3. Select the optical transceiver that corresponds to the type of fiber (single- or multi-mode)
required for the installation. The color of the transceiver (see transceiver color code in
Figure 19) corresponds to the fiber type.
4. Remove the transceiver from the anti-static packaging and orient for installation (see
Figure 19.).
Note: Two types of optical transceivers, type A and type B, are available. Both types
provide the same functionality. On the type A optical transceiver, the release lever (see
Figure 19) must be closed for installation.
