Installing the QSFP+ or QSFP28 Transceiver Modules in the Supervisor PIC
The 40-Gigabit (GE) QSFP+ and 100 Gigabit (QSFP28) transceiver module is a hot-swappable, parallel
fiber-optical module with four independent optical transmit and receive channels. These channels can terminate
in another 40-Gigabit QSFP+ transceiver, or the channels can be broken out to four separate 10-Gigabit SFP+
transceivers. The QSFP+ transceiver module connects the electrical circuitry of the system with an optical
external 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.

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.
Before You Begin
Do not install or remove the QSFP28 module with fiber-optic cables still attached to it. Doing so may
damage cables, cable connectors, or the optical interfaces and may interfere with the QSFP28 module
latching properly into its socket connector. Disconnect all cables before removing or installing an QSFP28
module.
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 coming
into contact with system modules.
Caution
•
Attach an ESD-preventive wrist strap to your wrist and connect the other end to the grounding lug
connected to the chassis.
