6. Insert the new Optical Module into the optical interface.
a. Take out the new Optical Module from the ESD bag and check whether
there is any damage or component missing. Check whether the new
Optical Module is of the same type as the Optical Module to be replaced.
b. Insert the new Optical Module into the optical interface, as shown in
Figure 4-80. When the click of the reed in the Optical Module is heard, it
indicates that the Optical Module is correctly inserted. If the new Optical
Module is a CFP one, insert the new Optical Module into the optical port
of the card, push the transceiver panel horizontally into the connector
using even force with both thumbs. After the transceiver is inserted, push
the transceiver slightly to ensure that it has reached the stop position.
Pull out the two screw rods slightly to ensure that they can properly
function. Pre-tighten one of the screw rods. Then, tighten the other screw
rod. After that, tighten the
rst screw rod. To prevent the Optical Module
from getting loosened due to vibration or collision, you are advised to use
a screwdriver to tighten the screw rods.
