Installing SFP Modules

Installing an SFP or SFP+ Module

Before you begin

When installing SFP or SFP+ modules, follow these guidelines:

  • Do not remove the dust plugs from the modules or the rubber caps from the fiber-optic cable until you are ready to connect the cable. The plugs and caps protect the module ports and cables from contamination and ambient light.

  • To prevent ESD damage, follow your normal board and component handling procedures when connecting cables to the switch and other devices.


    Caution

    Removing and installing an SFP or SFP+ module can shorten its useful life. Do not remove and insert any module more often than is absolutely necessary.

Procedure

Step 1

Attach an ESD preventive wrist strap to your wrist and to a bare metal surface.

Step 2

Find the send (TX) and receive (RX) markings on the module top.

On some SFP or SFP+ modules, the send and receive (TX and RX) markings might be replaced by arrows that show the direction of the connection.

Step 3

If the module has a bale-clasp latch, move it to the open, unlocked position.

Step 4

Align the module in front of the slot opening, and push until you feel the connector snaps into place.

Step 5

If the module has a bale-clasp latch, close it.

Step 6

For fiber optic SFP or SFP+ modules, remove the dust plugs and save.

Step 7

Connect the SFP cables.

Removing an SFP or SFP+ Module

Procedure

Step 1

Attach an ESD preventive wrist strap to your wrist and to a bare metal surface.

Step 2

Disconnect the cable from the SFP module. For reattachment, notice which cable connector plug is send (TX) and which is receive (RX).

Step 3

Insert a dust plug into the optical ports of the SFP or SFP+ module to keep the optical interfaces clean.

Step 4

If the module has a bale-clasp latch, pull the bale out and down to eject the module. If the latch is obstructed and you cannot use your finger, use a small, flat-blade screwdriver or other long, narrow instrument to open the latch.

Step 5

Grasp the SFP or SFP+ module, and carefully remove it from the module slot.

Step 6

Place the module in an antistatic bag or other protective environment.
