Use LC-LC or LC-SC fiber-optic cables to connect the switch-module external
ports to external Fibre Channel devices. For more information, see the
documentation that comes with the cable options.
✏ NOTE
You can remove and replace an SFP module while the switch module is
operating without damaging the switch module or the SFP module. However,
transmission on the affected port will be interrupted until the SFP module and
cables are installed. See the documentation that comes with the connected Fibre
Channel device for information about installation, configuration, and startup

xx
CAUTION:
Hazardous voltage, current, and energy levels are present inside any component that
has this label attached. There are no serviceable parts inside these components. If you
suspect a problem with one of these parts, contact a service technician.
Complete the following steps to replace a switch module:
1. Review the information in “Safety and regulatory information” on page v
and
“Installation guidelines” on page 12 through “Handling static-sensitive devices” on
page 13.
2. Remove the acoustic attenuation module, if any, from the rear of the
SBCE unit. For
more information, see the illustration in step
2 on page 14 and the Intel Server
Chassis SBCE Installation and User’s Guide on the
Resource CD that came with
your SBCE unit.
3. Remove the LC-LC or LC-SC fiber-optic cables from the two external ports on the SFP
module. Removing these cables disrupts the network connection from the external
Fibre Channel port to any connected external Fibre Channel devices. For removal
instructions, see the documentation that comes with the cable options.
