Chapter 4: Installing the SFP+ and QSFP+ Transceivers and Cables

56

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.

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 AT-DC2552XS.
