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.
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.
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.
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:
1?for fiber-optic sfp modules, insert the lc or mt-rj cable connector into the sfp module.
2?for copper sfp modules, insert the rj-45 cable connector into the sfp module.
when connecting to 1000base-t sfp modules, be sure to use a twisted four-pair, category 5 cable.
