10.1.8 Combo port
At QX-S5524GP-4X1C, a SFP port (17S to 24S) port and a 10/100/1000BASE-T
autosensing Ethernet port (17T to 24T) are a combo port. Only one of these two ports can
operate at a time.
The two ports share one forwarding channel and one interface view. As a result, they
cannot work simultaneously. When you activate one port using combo enable { copper |
fiber } command, the other port is automatically disabled.
10.1.9 Port LED mode switching button
The QX-S5500G Series can change a mode of a Port mode LED using a Port LED mode
switching button.
For more information about a Port LED mode switching button, see “Port mode LED” of
“LED” of “Appendix C Ports and LEDs".
10.2 Twisted pair cable
The QX-S5500G Series uses Category-5 (or above) twisted pair cable and the maximum
length for a cable segment is 100 meters (328 feet).
NOTE:
You must use Category5 cable or better (including Cat5e, Cat6 and Cat6A).
Twisted pair cable is used for the connecting to 10/100/1000BASE-T autosensing Ethernet port,
1000BASE-T-SFP, and Management Ethernet port.
I. RJ-45 connector
Twisted pair cable uses RJ45 connector shown in Figure 10-6.
