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.

Installing an interface card

1. Wear an ESD-preventive wrist strap, and make sure it makes good skin contact and is well

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.
