Ethernet interfaces
1) Introduction
The WX5002V2 provides two 10/100/1000 Base-T autosensing Ethernet electrical interfaces and two
1000 Base-X SFP optical interfaces. One electrical interface and one optical interface form a Combo
port, which is marked in a white box on the front panel. Only one interface (either electrical or optical) of
a Combo port can be used at a time.
z
Ethernet electrical interfaces support 10/100/1000 Mbps autosensing. Table 1-8 describes the
working mode of the interfaces in each speed.
Table 1-8 Speed and working mode of an electrical Ethernet interface
Speed Working mode
10 Mbps (autosensing) Half/full duplex, auto-negotiation
100 Mbps (autosensing) Half/full duplex, auto-negotiation
1000 Mbps (autosensing) Full duplex, auto-negotiation
z
Ethernet optical interfaces support 1000 Mbps full duplex. The optical interface and the electrical
interface of a Combo port share the same LED.
z
A Combo port can work in either the electrical interface mode or the optical interface mode, that is,
either the electrical interface or the optical interface of a Combo port can be used at a time.
z
A Combo port supports optical-electrical automatic switching, however, when both the optical and
electrical interfaces are connected, the electrical interface will be used in precedence.
2) SFP interface modules
The WX5002V2 provides four SFP GE optical interfaces. The following SFP modules are available:
