Install and Remove QSFP+/QSFP28 Transceiver Modules
This section provides the installation, cabling, and removal instructions for the 40-Gigabit Quad Small
Form-Factor Pluggable Plus (QSFP+) and 100 Gigabit (QSFP28) transceiver modules. The modules are
hot-swappable input/output (I/O) devices that connect the system’s module port electrical circuitry with either
a copper or a fiber-optic network.
The following figure shows the 40-Gigabit optical QSFP+ transceiver. The transceiver is used primarily in
short reach applications in switches, routers, and data center equipment where it provides higher density than
SFP+ modules. The 100-Gigabit optical QSFP28 transceiver is similar to the 40-Gigabit optical QSFP
transceiver.

Required Tools and Equipment
You need these tools to install the 40-Gigabit QSFP+ / 100-Gigabit QSFP28 transceiver modules:
• 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.
For information on inspecting and cleaning fiber-optic connections, see Maintain Transceivers and Optical
Cables.
Installing the 40-Gigabit QSFP+ or 100-Gigabit Transceiver Module
The QSFP+ or QSFP28 transceiver module can have either a bail-clasp latch or a pull-tab latch. Installation
procedures for both types of latches are provided.
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 coming into
contact with system modules.
