Remove The 100-Gigabit Qsfp28 Transceiver Module - Cisco NCS 540 Hardware Installation Manual

Install the Device
Note The multiple-fiber push-on (MPO) connectors on the optical QSFP+ or QSFP28 transceivers support network
interface cables with either physical contact (PC) or ultra-physical contact (UPC) flat polished face types.
The MPO connectors on the optical QSFP+ or QSFP28 transceivers do not support network interface cables
with an angle-polished contact (APC) face type.
Step 1
Remove the dust plugs from the optical network interface cable MPO connectors. Save the dust plugs for future use.
Step 2 Inspect and clean the MPO connector's fiber-optic end faces.
Step 3
Remove the dust plugs from the QSFP+ or QSFP28 transceiver module optical bores.
Step 4 Immediately attach the network interface cable MPO connectors to the QSFP+ or QSFP28 transceiver module (see the
figure below).

Caution
The QSFP+ or QSFP28 transceiver module is a static-sensitive device. Always use an ESD wrist strap or
similar individual grounding device when handling QSFP+ or QSFP28 transceiver modules or when coming
into contact with modules.
To remove a QSFP+ or QSFP28 transceiver module, follow these steps:
Step 1
For optical QSFP+ or QSFP28 transceiver modules, disconnect the network interface cable from the QSFP+ or QSFP28
transceiver connector.
Step 2
For QSFP+ or QSFP28 transceiver modules equipped with a bail-clasp latch (see the below figure, top view):
a) Pivot the bail-clasp down to the horizontal position.
b) Immediately install the dust plug into the transceivers optical bore.
c) Grasp the sides of the QSFP+ or QSFP28 transceiver and slide it out of the module socket.
Step 3 For QSFP+ or QSFP28 transceivers equipped with a pull tab latch (see the below figure, bottom view):
a) Immediately install the dust plug into the transceiver's optical bore.
b) Grasp the tab and gently pull to release the transceiver from the socket.
