Chapter 2 Switch Installation
Installing a Network Module in the Switch
Use only Cisco network modules and SFP or SFP+ modules with the switch. For information about
supported SFP modules, see the
“SFP and SFP+ Modules” section on page 1-8
.
For more information about installing, removing, cabling, and troubleshooting network modules, see the
module documentation on Cisco.com. For module cable specifications, see
Appendix B, “Connector and
Cable Specifications.”
Tools and Equipment
You need to supply a number-2 Phillips screwdriver.
Installing Network Modules
When installing network modules, observe these general precautions:
•
Do not remove the EMC plug from the 10-Gigabit Ethernet slot until you are ready to install an SFP
or SFP+ module. Either a module or a dust plug must be installed in the slot at all times.
•
Do not remove the dust plugs from the fiber-optic SFP modules or the rubber caps from the
fiber-optic cable until you are ready to connect the cable. The plugs and caps protect the module
ports and cables from contamination and ambient light.
•
Removing and installing a network module can shorten its useful life. Do not remove and insert any
network module more often than necessary.
•
To prevent ESD damage, follow your normal board and component handling procedures when
connecting cables to the switch and other devices.
Step 1
Attach an ESD-preventive wrist strap to your wrist and to a bare metal surface.
Step 2
Remove the module from the protective packaging.
Step 3
Remove the 10-Gigabit Ethernet module slot EMC plug and save.
Caution
Verify the correct orientation of your module before inserting it into the slot. Incorrect insertion can
damage the module.
Step 4
Position the module face up to install in the module slot. See
Figure 2-22
. Slide the module into the
opening until the back of the module faceplate is flush with the switch faceplate. Fasten the captive
screws to secure the network module in place.
Caution
Do not insert or remove a network module with attached fiber-optic cables. A module interface might
change to an error-disabled state when a network module is inserted or removed with connected
fiber-optic cables. If the interface is in an error-disabled state, you can re-enable the interface by using
the
shutdown
and
no shutdown
interface configuration commands.
