Installing Dedicated CX4/SFP+ Cable
z
Make sure that you have installed a CX4/SFP+ interface module before installing dedicated
CX4/SFP+ cables.
z
The installation and removal procedures of a CX4 cable are similar to that of an SFP+ cable. This
section describes the installation and removal of the SFP+ cable for illustration.
Step1
Put on an ESD-preventive wrist strap and verify the ESD-preventive wrist strap properly grounded.
Then take out the dedicated SFP+ cable from the package.
Step2
Horizontally plug the plug of the dedicated SFP+ cable into the SFP+ port of the switch and pay
attention to the direction of the plug when plugging it.
Removing Dedicated CX4/SFP+ Cable
Step1
Put on an ESD-preventive wrist strap and verify the ESD-preventive wrist strap properly grounded.
Step2
Hold the plug of the SFP+ cable, pull the handle at the end of the plug to horizontally unplug the plug of
the SFP+ cable from the SFP+ port of the switch.
z
Dedicated CX4/SFP+ cable of the S5120-EI series is hot pluggable.
z
Make sure that the cable bending radius is no less than eight times of the cable diameter when
dedicated CX4/SFP+ cable is connected.
Installing Switches for a Stack
The S5120-28C-EI, S5120-52C-EI, S5120-28C-PWR-EI, and S5120-52C-PWR-EI support the IRF
function. You can install IRF-capable interface modules to connect multiple switches through the 10 GE
ports to form a logical entity, thus to establish a new intelligent network with high reliability, expandability
and manageability.
