Installing QSFP+ Transceivers
• Do not remove and insert a transceiver more often than is necessary. Repeated removals and insertions
• Keep the transceivers and fiber-optic cables clean and dust free to maintain high signal accuracy and to
• Clean these parts before installation to prevent dust from scratching the fiber-optic cable ends.
• Clean the connectors regularly; the required frequency of cleaning depends upon the environment. In
• Do not touch the ends of connectors. Touching the ends can leave fingerprints and cause other
• Inspect routinely for dust and damage. If you suspect damage, clean and then inspect fiber ends under a

Installing QSFP+ Transceivers
The QSFP+ transceiver module can have either a bail-clasp latch or a pull-tab latch.
Caution
The QSFP+ transceiver module is a static-sensitive device. Always use an ESD wrist strap or similar individual
grounding device when handling QSFP+ transceiver modules or coming into contact with system modules.
Step 1
Attach an ESD wrist strap to yourself and a properly grounded point on the chassis or the rack. Follow its instructions
for use.
Step 2
Remove the QSFP+ transceiver module from its protective packaging.
Step 3
Remove the dust cover from the port end of the transceiver.
Step 4
Check the label on the QSFP+ transceiver module body to verify that you have the correct model for your network.
Step 5
For optical QSFP+ transceivers, remove the optical bore dust plug and set it aside.
Step 6
For transceivers equipped with a bail-clasp latch, do the following:
a) Keep the bail-clasp aligned in a vertical position.
b) Align the QSFP+ transceiver in front of the module's transceiver socket opening and carefully slide the QSFP+
transceiver into the socket until the transceiver makes contact with the socket electrical connector.
Step 7
For QSFP+ transceivers equipped with a pull-tab, do the following:
a) Hold the transceiver so that the identifier label is on the top.

prevent damage to the connectors. Attenuation (loss of light) is increased by contamination and should
be kept below 0.35 dB.
addition, clean connectors if they are exposed to dust or accidentally touched. Both wet and dry cleaning
techniques can be effective; refer to your site's fiber-optic connection cleaning procedures.
