Chapter 4: Installing the SFP+ and QSFP+ Transceivers and Cables
Installing SFP+ Transceivers and Cables
General Guidelines
Review the following guidelines before installing optional SFP+ transceivers or SFP+ direct attach cables in the switch:
SFP+ transceivers and SFP+ direct attach cables can be hot- swapped while the switch is powered on. For a SFP+ transceiver, you should always disconnect the fiber optic cable before removing a module.
When you are installing a SFP+ transceiver, you should install the module before connecting the fiber optic cable.
Fiber optic modules are dust sensitive. Always keep the plug in the optical bores when a fiber optic cable is not installed or when you store the module. When you do remove the plug, keep it for future use.
Unnecessary removal and insertion of a module can lead to premature failure.
Warning
A module can be damaged by static electricity. Be sure to observe all standard electrostatic discharge (ESD) precautions, such as wearing an antistatic wrist strap, to avoid damaging the device.
Go to “Optional SFP+ Transceivers” on page 17 for a list of approved SFP+ transceivers for the
