Installing the QSFP+ or QSFP28 Transceiver Modules in the Supervisor PIC
Required Tools and Equipment
• Wrist strap or other personal grounding device to prevent ESD occurrences.
• Antistatic mat or antistatic foam to set the transceiver on.
• Fiber-optic end-face cleaning tools and inspection equipment.
Step 1
Attach an ESD wrist strap to yourself and a properly grounded point on the chassis or the rack.
Step 2 Remove the QSFP+ or QSFP28 transceiver module from its protective packaging.
Step 3
Check the label on the QSFP+ or QSFP28 transceiver module body to verify that you have the correct model for your
network.
Step 4
For optical QSFP+ or QSFP28 transceiver modules, remove the optical bore dust plug and set it aside.
Step 5 For QSFP+ or QSFP28 transceiver modules equipped with a pull-tab, hold the transceiver so that the identifier label is
on the top.
Step 6 For QSFP+ or QSFP28 transceiver modules equipped with a bail-clasp latch, keep the bail-clasp aligned in a vertical
position.
Step 7
Align the QSFP+ or QSFP28 transceiver module in front of the module's transceiver socket opening and carefully slide
the QSFP+ or QSFP28 transceiver into the socket until the transceiver makes contact with the socket electrical connector
(see the figure below).

Step 8 Press firmly on the front of the QSFP+ or QSFP28 transceiver module with your thumb to fully seat the transceiver in
the module's transceiver socket (see the below figure).
Caution If the latch is not fully engaged, you might accidentally disconnect the QSFP+ or QSFP28 transceiver module.
