ATTENTION
You must disable Auto-Negotiation before operating the 1000BASE-T SFP.
By default, SFPs inserted into certain product-specific modules are set for
Auto-Negotiation = True.
The maximum current requirement of the SFP is 375 milliamperes (mA) at
5 volts (V).
The following table describes the 1000BASE-T SFP specifications.
