Laser Safety Guidelines - Cisco Catalyst 8300 Series Hardware Installation Manual

Laser Safety Guidelines

• Do not remove the dust plugs from the SFP and SFP+ modules or the rubber caps from the fiber-optic
• Removing and installing an SFP and SFP+ module can shorten its useful life. Do not remove and insert
• To prevent ESD damage, follow your normal board and component handling procedures when connecting
• When you insert several SFP and SFP+ modules in multiple ports, wait for 5 seconds between inserting
Step 1
Attach an ESD-preventive wrist strap to your wrist and to an earth ground surface.
Step 2 Find the send (TX) and receive (RX) markings that identify the top of the SFP/SFP+ module.
On some SFP/SFP+ modules, the send and receive (TX and RX) markings might be shown by arrows that show the
direction of the connection.
Step 3 If the SFP/SFP+ 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 snap into place.
Step 5
If the module has a bale-clasp latch, close it to lock the SFP/SFP+ module in place.
Step 6 Remove the SFP and SFP+ dust plugs and save.
Step 7
Connect the SFP and SFP+ cables.
Laser Safety Guidelines
Optical Small-Form Pluggable (SFPs) use a small laser to generate the fiber-optic signal. Keep the optical
transmit and receive ports covered whenever a cable is not connected to the port.
