Installing Optics
This section contains two subsections:
• Installing SFPs on page 43
• Installing XFPs on page 44
The S50N and S50V each have four receptacles at the right end of their faceplates that accommodate
10/100/1000 SFP optical transceivers.
On the back of the switches, there are two bays that accept either stacking modules or 10GbE modules
(CX4 or XFP). A 10GbE module contains two ports. 10GbE modules should only be inserted or removed
when the switch is powered down, as detailed in
Inserting Optional Modules (10-Gigabit or Stacking) on
page 17
in
Chapter 4, Installing the Switch
.
SFP and XFP transceivers can be inserted or removed while the switch is running.
CAUTION: Before connecting a transceiver to a source, check the receive power of the transceiver with an
optical power meter. Generally, Dell Force10 specified optics are not to be subjected to receive power higher
than that stipulated by the optic specification. If the optic is exposed to optical power in excess of the
specification, there is a high likelihood that it will be damaged. Optical specifications for Dell Force10 branded
devices are at the following URL:

Dell Force10 offers various types of SFP and XFP transceivers. For details, see:

Installing SFPs
To install an SFP transceiver into an open optical port at the right front of the switch, use the steps below:
