Dell Force 10 S50N Guide De Démarrage Rapide page 9

Connect the grounding cable to the FG terminal first, then connect the opposite
end to the appropriate grounding point at your site to ensure an adequate chassis
ground.
Install the SFP and XFP Optics
The S50N and S50V each have four receptacles at the right end of their
faceplates that accommodate 10/100/1000 SFP optical transceivers.
A 10GbE module contains two ports. 10GbE modules should only be inserted or
removed when the switch is powered down. Refer to the
guide for information related to optional module installation.
Systems
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, 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.
CAUTION: Electrostatic discharge (ESD) damage can occur if components
are mishandled. Always wear an ESD-preventive wrist or heel ground strap
when handling the chassis and its components.
WARNING: Follow all warning labels when working with optical fibers.
Always wear eye protection when working with optical fibers. Never look
directly into the end of a terminated or unterminated fiber or connector as it
may cause eye damage.
Step Task
Position the SFP or XFP so it is in the upright position. (The SFP optic
1
has a key that prevents it from being inserted incorrectly.).
Insert the optic into the port until it gently snaps into place.

CAUTION: You can insert and connect XFP transceivers while the switch is
operating. You can also disconnect and remove XFP transceivers while the
switch is operating. However, inserting or removing the module is not
supported; it can crash or lock up the switch, requiring a reboot.
