Step 8
For optical QSFP+ modules, reinstall the dust plug into the QSFP+ transceivers optical bore until you
are ready to attach the network interface cable. Do not remove the dust plug until you are ready to attach
the network interface cable.
Attaching the Optical Network Cable
Before removing the dust plugs and making any optical connections, follow these guidelines:
–
Keep the protective dust plugs installed in the unplugged fiber-optic cable connectors and in the
transceiver optical bores until you are ready to make a connection.
–
Inspect and clean the MPO connector or the duplex LC connector end faces just before you
make any connections. See the Tip following step 2 in the next procedure for a pointer to a
fiber-optic inspection and cleaning white paper.
–
Grasp the MPO or the duplex LC connector only by the connector housing to plug or unplug a
fiber-optic cable.
Note
The MPO connectors on the 40-Gigabit SR4 and CSR4 QSFP+ transceiver modules are keyed
to prevent incorrect insertion.
