For detailed instructions on installing, removing, and cabling the SFP module,
refer to your SFP module documentation.
Figure 3-37
shows an SFP module that has a bale-clasp latch.
We strongly recommend that you do not install or remove fiber-optic SFP
modules with cables attached because of the potential damage to the cables, the
cable connector, or the optical interfaces in the SFP module. Disconnect all cables
before removing or installing an SFP module.
Removing and installing an SFP module can shorten its useful life. Do not remove
and insert SFP modules more often than is absolutely necessary.
