Installation
2. Gently insert the transceiver module into the
module socket of your device. Press the dust
plug until it locks into place.
3. Verify the transceiver module is locked into
place by trying to remove it from the module
socket without releasing the latch. If it stays
in place, it is seated properly. If not, reinsert
it by firmly pressing on the dust plug until it
locks into place.
4. Once you have verified the transceiver
module is locked securely in place, remove
the dust plug from the LC optical bores and
connect your cabling.
Note: Save the dust plug so it can be used in the
event the transceiver module needs to be uninstalled
and reinstalled.
