z You are recommended to use SFP transceivers of H3C on the S5120-EI series.
z The S5120-EI series Ethernet switches support GE SFP transceivers only.
z The types of SFP transceivers may update with time. For information about transceivers, contact
H3C technical support or marketing staff.
z For the models and specifications of each kind of transceivers, refer to H3C Low End Series
Ethernet Switches Pluggable Modules Manual.
Combo Port
Each SFP port and the corresponding 10/100/1000Base-T Ethernet port form a Combo port. For each
Combo port, either the SFP port or the corresponding 10/100/1000Base-T Ethernet port can be used at
a time. For details about the combo port mapping relationship, please refer to
Table 1-5.

The SFP port and its corresponding 10/100/1000Base-T autosensing Ethernet port cannot be used
together at the same time. For details, refer to the Ethernet Port Configuration part in the Access
Volume of the H3C S5120-EI Series Ethernet Switches Operation Manual.
