Installing and Removing SFP Modules
Caution:
When you use commercial SFP modules such as CWDM and 1000BX-U/D, reduce the maximum operating
temperature by 59°F (15°C). The minimum operating temperature is 32°F (0°C).
Caution:
To prevent electrostatic-discharge (ESD) damage, follow standard board and component handling
procedures.
Warning:
Do not insert and remove SFP modules while power is on; an electrical arc can occur. This could cause an
explosion in hazardous location installations. Be sure that power is removed or the area is nonhazardous before
proceeding. Statement 1087
Note:
Removing and installing an SFP module can shorten its useful life. Do not remove and insert any module more often
than is absolutely necessary.

Caution:
Do not install or remove the LC SFP module with fiber-optic cables attached because of 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.
Installing Fiber Optic SFP Modules
Warning:
Class 1 laser product. Statement 1008
To install and cable an optical SFP transceiver uplink port:
1.
Attach an ESD-preventive wrist strap to your wrist and to a bare metal surface.
2.
Find the send (TX) and receive (RX) markings on the module top.
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).
3.
If the module has a bale-clasp latch, move it to the open, unlocked position.
4.
Align the module in front of the slot opening, and push until you feel the connector snap into place.
5.
If the module has a bale-clasp latch, close it.
6.
For fiber-optic SFP modules, remove the dust plugs and save.
7.
Connect the SFP cables.
