Installing and Removing SFPs

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

You can replace the SFPs without disabling the interfaces or removing the module

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 on page 44):
