Installing and removing an interface card
Each S5120-EI switch (except the S5120-24P-EI and S5120-48P-EI) provides two expansion slots on the
rear panel. For optional interface cards, see " Interface cards ."
The installation and removal of various interface cards are similar. This section describes the installation
and removal of the 2-Port 10 GE SFP+ Interface Card (LSPM2SP2P) for illustration.

grounded.
2. Loosen the mounting screws of the filler panel on the interface card slot of the switch's rear panel
with a Phillips screwdriver and remove the filler panel, as shown in
Figure 22 .
