H3C WX5004 Installation Manual page 46

NOTE:
 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.
 A combo port supports optical-electrical automatic switching, however, when both the
optical and electrical interfaces are connected, the electrical interface is used.
SFP interface modules
The WX5004 provides four SFP GE optical interfaces. The following SFP modules are
available:

