2.4 Description of the integrated fiberglass transceivers
Some versions of the FL SWITCH 2000 series have integrated fiberglass transceivers with
an SC duplex or ST duplex pin connector pattern.
When the device has been mounted in accordance with the instructions (see Figure 21), the
output port or the sending diode (TX) of the fiberglass transceiver is always at the top, the
input port or the receiving diode (RX) is always at the bottom.

2.5 Description of the combo ports
Combo ports enable a high degree of flexibility when setting up networks. They consist of a
corresponding RJ45 port (e.g., XF3.1) and a corresponding SFP port (e.g., XF3.2). Only
one port of the pair can be used at a time. Each combo port can therefore be used as a
copper or fiberglass port. Inserting an SFP module disables the corresponding RJ45 port. If
a combo port is used as a fiberglass port, the Link LED of the corresponding RJ45 port lights
up orange when there is an active connection.
The following FL SWITCH 2000/FL NAT 2000 versions have combo ports:
– FL SWITCH 2204-2TC-2SFX (port 3 and port 7)
– FL SWITCH 2212-2TC-2SFX (port 3 and port 7)
– FL SWITCH 2304-2GC-2SFP (port 3 and port 7)
– FL SWITCH 2312-2GC-2SFP (port 3 and port 7)
– FL SWITCH 2404-2TC-2SFX (port 3 and port 4)
– FL SWITCH 2412-2TC-2SFX (port 3 and port 4)
– FL SWITCH 2504-2GC-2SFP (port 3 and port 4)
– FL SWITCH 2512-2GC-2SFP (port 3 and port 4)
– FL NAT 2304-2GC-2SFP (port 3 and port 7)
