Installing SFP Modules
Figure 2-12
We strongly recommend that you do not install or remove fiber-optic SFP modules with cables attached
Caution
because of the potential damage to the cables, the cable connector, or the optical interfaces in the SFP
module. Disconnect all cables before removing or installing an SFP module.
Removing and installing an SFP module can shorten its useful life. Do not remove and insert SFP
modules more often than is absolutely necessary.
Figure 2-12
To insert an SFP module into the module slot, follow these steps:
Attach an ESD-preventive wrist strap to your wrist and to a bare metal surface on the chassis.
Step 1
Some SFP modules identify the top side of the module with send (TX) and receive (RX) markings or
arrows that show the direction of the connection.
If the SFP module that you are using has the markings, use them to identify the top side of the module.
Step 2
Step 3
Align the SFP module in front of the slot opening.
Step 4
Insert the SFP module into the slot until you feel the connector on the module snap into place in the rear
of the slot (see
