Replacing a transceiver module
WARNING!
When you install or remove a module:
• Do not stare at the fibers to avoid hurting your eyes.
• Do not touch the golden fingers on the module.
Make sure the optical transceiver modules at the two ends of an optical fiber are of the same model.
Replacing an XFP/SFP+/SFP/QSFP+ module
1. Wear an ESD wrist strap and make sure it has a good skin contact and is well grounded. For more
information, see "Installing FRUs."
2. Remove the optical fibers on the module.
3. Pivot the clasp down to the horizontal position.
For a QSFP+ module that uses a plastic pull latch, skip this step. QSFP+ modules use either a metal
or plastic pull latch.
4. Grasp the clasp on the module and carefully pull the module out of the slot.
5. Put the dust plug on the removed module, and put the removed module into its original shipping
materials.
6. Install a new module.
For the installation procedures, see "Installing FRUs."

Replacing an SFP+/QSFP+/QSFP+ to SFP+ cable
When you replace an SFP+/QSFP+/QSFP+ to SFP+ cable, follow these guidelines:
• The bend radius of the cable must be at least eight times the cable diameter.
•
When you remove a cable, pull the pull latch horizontally. Otherwise, the cable cannot be removed
smoothly, or even the module or slot could be damaged.
