Planning The Cabling Scheme - H3C S5500-HI Switch Series Installation Manual

Planning the cabling scheme

Select appropriate cables to connect physical IRF ports:
Use XFP transceiver modules and fibers to connect XFP ports.
•
Use SFP+ transceiver modules and fibers to connect SFP+ ports over a long distance, and use SFP+
•
cables over a short distance.
Use CX4 cables to connect CX4 ports.
•
• Use category 6 or above twisted pair cables to connect 1/10GBase-T Ethernet ports.
If the IRF member switches are far away from one another, choose the SFP+/XFP transceiver modules
with optical fibers. If the IRF member switches are all in one equipment room, choose CX4/SFP+ cables
or twisted pair cables.
For the transceiver modules and cables available for IRF connections, see
modules/SFP+
The following subsections describe several H3C recommended IRF connection schemes, and all these
schemes use a ring topology.
IMPORTANT:
In these schemes, all physical IRF ports are located on the same side. If physical IRF ports are on different
sides, you must measure the distance between them to select an appropriate cable.
Connecting the IRF member switches in one rack
Use CX4/SFP+ cables or twisted pair cables to connect the IRF member switches (nine switches in this
example) in a rack as shown in
same order as connected in the rack.
