Removing an SFP optical module
Remove an optical module to replace it or re-deploy it.
Prerequisites
• You must be familiar with “Safety considerations and best practices”
(page 53).
• The FP should already be installed in the shelf.
• The FP port of the SFP module must be locked in software. For the
procedure on locking a port, see 241-5701-600 Passport 7400, 15000,
20000 Configuration Guide.
• Do not touch the circuitry inside the large open end of an SFP optical
module or you may cause the unit to malfunction. Refer to the figure “A
typical SFP optical module” (page 760).
• A failed optical module generates alarm 7011 5480.
Procedure steps
1 Unplug each cable that is attached to the optical module by pressing on
the release tab and gently pulling straight away until the fiber is fully
disengaged.
2 Remove the SFP module by:
• swinging the bale latch away from the body of the SFP until it is at
about a 90-degree angle relative to the SFP
• pulling the latch along the axis of the SFP until the module is fully
disengaged
For an example, see the figure “Orientation of an installed SFP module in
an NTHW49” (page 761).
