Installing and Removing SFP Modules
Installing SFP Modules into SFP Module Slots
This section provides instructions for how to install an SFP module that has a bale-clasp latch.
Caution We strongly recommend that you do not install or remove fiber-optic SFP modules with cables attached
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.
Note Refer to the Installation Notes for the Cisco Small Form-Factor Pluggable Modules on cisco.com for
instructions to install SFPs that use other types of latches.
Figure 2-12 shows an SFP module that has a bale-clasp latch.

To insert an SFP module into the SFP 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 Find the send (TX) and receive (RX) markings that identify the top side of the SFP module.
Note On some SFP modules, the send and receive (TX and RX) markings might be replaced by arrows
that show the direction of the connection, either send or receive (TX or RX).
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
Figure 2-13 .)
