Step 5
For fiber-optic SFP modules, remove the dust plugs from the optical ports, and store them for later use.
Caution Do not remove the dust plugs from the fiber-optic SFP module port or the rubber caps from the
fiber-optic cable until you are ready to connect the cable. The plugs and caps protect the SFP module
ports and cables from contamination and ambient light.
Step 6 Insert the cable connector into the SFP module:
• For fiber-optic SFP modules, insert the LC or MT-RJ cable connector into the SFP module.
• For copper SFP modules, insert the RJ-45 cable connector into the SFP module.
Note When you connect to 1000BASE-T SFP modules, be sure to use a twisted four-pair, Category 5
or later cable.
Removing SFP Modules from SFP Module Slots
To remove an SFP module from a module slot, follow these steps:
Step 1 Attach an ESD-preventive wrist strap to your wrist and to a bare metal surface on the chassis.
Step 2 Disconnect the cable from the SFP module.
Tip For reattachment, note which cable connector plug is send (TX) and which is receive (RX).
