QX-S5500 Series Ethernet Switches
1.5 Optional Interface Modules
QX-S5500 series provide two interface module slots on the rear panel. You can select the
interface modules in Table 1-14 as needed.
QX-S5500 series support IRF, requiring physical connections between devices. The 10 GE
ports of the supported interface modules support IRF, allowing you to connect the switches
through these 10 GE ports for IRF implementation.

A 2-port 10 GE CX4 interface module provides two 10 Gbps electrical ports and supports
CX4 electrical and protocol standards. Only NEC's CX4 cables can be used for connecting
the CX4 ports. A CX4 cable is hot swappable and its maximum transmission distance is 3 m,
which is suitable for short-distance connections only.
