This section describes how to replace small form-factor pluggable
transceivers (SFPs) on IOAs that support these devices. A range of
SFPs that support different optical modes (multimode, single mode,
and so forth) and cabling distances is available. You can replace
the SFPs without disabling the interfaces or removing the module from
To install SFPs:
Ground yourself by using an antistatic wrist
strap or other device and connect it to an ESD grounding jack.
Identify the following items on the SFP (Figure 22):
The connection circuitry on the base
The cable connectors on the front (which are protected
by a dust cover)
Figure 22: Representative SFP
Be sure to position the SFP correctly before you install it.
Hold the SFP so that:
The connection circuitry is adjacent to the LK and ACT
markings on the IOA's faceplate.
The cable connectors will be visible when you install
