Planning The Cabling Scheme - H3C FS5100-EI Series Manual

Planning the cabling scheme

Use the following cables to connect the IRF physical ports on the switches:
•
10/100/1000BASE-T autosensing Ethernet port—Category 5 or above twisted-pair cable.
•
5G/2.5G/1000/100BASE-T autosensing Ethernet port—Category 5e or above twisted-pair
cable.
•
SFP port—GE SFP fiber transceiver module and optical fiber, GE SFP copper transceiver
module and twisted pair cable or GE SFP cable. For the available transceiver models and
cables, see ports in FS5100-EI Switch Series Hardware Information and Specifications.
•
SFP+ port—SFP+ fiber transceiver module and optical fiber or SFP+ cable. For the available
transceiver models and cables, see ports in FS5100-EI Switch Series Hardware Information
and Specifications.
If the IRF member switches are far away from one another, use SFP/SFP+ transceiver modules and
optical fibers. If the IRF member switches are all in one equipment room, use twisted pair cables or
SFP/SFP+ cables.
As a best practice, use ring topology to connect the switches. The following describes cabling
schemes in ring topology.
Connecting the IRF member switches in one rack
Use SFP cables to connect the IRF member switches in a rack as shown in Figure4-4. The switches
in the ring topology (see Figure4-5) are in the same order as connected in the rack.
