1000BASE-T SFP specifications
The 1000BASE-T SFP provides gigabit Ethernet connectivity using a single eight-pin RJ-45
connector. The 1000BASE-T SFP only operates at 1 Gb/s and does not support 100BASE-T
or 10BASE-T interfaces. The part number for this model is AA1419043-E6.
Important:
You must disable autonegotiation before you operate the 1000BASE-T SFP. After you insert
SFPs into certain product-specific modules, the system activates autonegotation by
default.
The maximum current requirement of the SFP is 375 milliamperes (mA) at 5 volts (V).
The following table describes the 1000BASE-T SFP specifications.
