Supported SFP transceivers
The following section provides specifications for the supported SFP transceivers.
Autonegotiation
Use Autonegotiation to allow the device to automatically negotiate the best common data rate and
duplex mode to use between two Autonegotiation-capable Ethernet devices.
When you use a 1 Gigabit SFP transceiver on a 10 Gigabit SFP+ port, you must enable auto-
negotiate if it is not enabled already. However, if you use 1 Gigabit SFP transceivers on a VSP 4000
switch that is connected to third party switches at the remote end, you must have auto-negotiate
enabled at all times; this applies to SFP transceivers installed in a 1 Gigabit SFP port or a 10 Gigabit
SFP+ port.
For VSP 7254XSQ, auto-negotiation is always disabled for 1 Gigabit Ethernet transceivers. If using
a 1000BASE-T SFP, the remote 1000BASE-T interface must have auto-negotiation enabled. If not,
the link will not be established. Also note that because the SFP+ ports on the VSP 7254XSQ only
support 1 and 10 Gbps speeds, the AA1419043-E6 1000BASE-T SFP will only operate at 1G
speeds.
If you use 1 Gbps fiber SFP transceivers, auto-negotiation is always disabled so the remote end
must also have auto-negotiation disabled. Otherwise this is not a supported configuration with VSP
7254XSQ.
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 Gigabits per second (Gbps) speed. Operation at 100 or 10
Megabits per second (Mbps) speeds are not supported.
The part number for this model is AA1419043-E6.
The maximum current requirement of the SFP is 375 milliamperes (mA) at 5 volts (V).
The following table describes the 1000BASE-T SFP specifications.
