1.1 Overview
QX-S5500 Series Ethernet Switches (hereinafter referred to as the QX-S5500 series) are
Layer 3 Gigabit Ethernet switching products. QX-S5500 series are designed as distribution
or access devices for intranets and metropolitan area networks (MANs). Supporting
IPv4/IPv6 dual stack and 10 GE uplink interfaces, the QX-S5500 series provide abundant
service features and can also be used for connecting server groups in data centers.
QX-S5500 series support the Intelligent Resilient Framework (IRF) technology. You can
connect multiple QX-S5500 switches through 10 GE ports to form a logical entity, thus to
establish a new intelligent network with high reliability, expandability and manageability.
QX-S5500 series include 4 models, and have the system specifications as shown in Table
1-1.

NOTE:
At software Version 5.4.16 or later Version, when a loop was detected at the port where a loopback detection
feature is effective, while port mode is rate mode or duplex mode Ethernet Port Status LED flashes on and off
by the cycle for about 2 seconds greenly.
The port mode LED and the SFP port status LED together indicate the SFP port operation
status. Refer to Table 1-12 for details.

Product overview
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.

1.5.1 2-port 10G BASE-CX4 interface module (LS-CX2-T2)
Figure 1-9 2-port 10G BASE-CX4 interface module (LS-CX2-T2)
Figure 1-10 2-port 10G BASE-CX4 interface module front panel(LS-CX2-T2)
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.
