As a best practice, use H3C transceiver modules and cables for the switch.
H3C transceiver modules and cables are subject to change over time. For the most up-to-date list of H3C
transceiver modules and cables, contact your H3C sales representative or technical support engineer.
• For the specifications of H3C transceiver modules and cables, see H3C Transceiver Modules User Guide.
Combo interface
The S5130S-28S-HPWR-LI, S5120V2-28P-HPWR-LI, and S3100V3-28TP-PWR-SI switches each
provide four combo interfaces on the front panel. The S5120V2-12TP-HPWR-LI and S5024FV3-EI
switches each provide two combo interfaces on the front panel. The S5560S-28F-SI,
S5560S-28DP-SI, and S5130S-28F-SI switches each provide eight combo interfaces on the front
panel. Each combo interface contains an SFP port and a 10/100/1000BASE-T autosensing Ethernet
port. Only one of the two ports is active at a time.
