Connect the cables
Use cables to connect 10 G ports of the interface cards:
• The given XFP ports work with XFP optical transceivers and fibers
• The given SFP+ ports can work with SFP+ optical transceivers and fibers for long-haul
transmission; or they can be directly connected through dedicated SFP+ cables for
short-haul transmission
• The given CX4 ports use dedicated CX4 cables for connection
• The given 1/10GBase-T Ethernet ports use Category 6 or later twisted-pair cables for
connection
For how to connect the cables, see " Installing a dedicated CX4/SFP+ cable ."

Finish establishing an IRF virtual device
Drawing a plan for an IRF virtual device
Before implementing an IRF virtual device, draw a plan according to actual conditions of the user
network and network devices and take the following points into consideration:
Determine the number of IRF members and the bandwidth
You can determine the number of IRF members and the bandwidth according to the network scale.
The S5500-EI series support aggregation of the 10 GE ports. You can assign the two 10 GE ports of an
interface card to an aggregation group to expand the bandwidth for the IRF virtual device.
NOTE:
10 GE ports of different interface cards cannot join the same aggregation group in the IRF virtual device.
Therefore, 1-port XFP interface cards do not support port aggregation in the IRF virtual device.
Select the proper interface cards and cables
You can select the interface cards and cables according to the distance between members of the IRF
virtual device. For long-distance connections, use XFP/SFP+ optical modules and fibers to connect the
devices; for short-distance connections, use CX4/SFP+ cables or twisted-pair cables to connect the
devices. For relevant information, see " Interface cards ."
