Installation Guide

Procedure
Step 1 Attach an ESD-preventive wrist strap to your wrist and the other end 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.
Note
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 snapping into place.
Step 5 Close the module's bale-clasp latch.
Step 6 Connect the SFP cables to the modules.
Step 7 Store the dust plugs in a safe location.
Removing an SFP or SFP+ Module
Procedure
Step 1 Attach an ESD-preventive wrist strap to your wrist and the other end to a bare metal surface.
Step 2 Disconnect the cable from the SFP or SFP+ module. For purposes of reattachment, note which cable connector
plug is send (TX) and which is receive (RX).
Step 3 Insert the dust plugs 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 it from the module. If the latch is
obstructed and you cannot use your finger, use a small flat-blade screwdriver or any other long and 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 any other protective environment.
Establishing the System Ground
This section describes how to connect a system ground to the OLT.
Installations that rely solely on system grounding using only an AC third-prong ground, run a substantially
greater risk of equipment problems and data corruption than those installations that use both the AC third-prong
ground and a properly installed system ground.
Caution
The system ground provides additional grounding for EMI shielding requirements and grounding for the low
voltage supplies (DC-DC converters) on the modules. You must observe the following system grounding
guidelines for your chassis:
