The SC connectors have a square interface and the
“conductors” are typically locked together through the
connector.

6.7 Using the FL SEC PAC Kit for Port Security
Layer 1 Port security for up to 4 ports is provided by
purchasing the FL SEC PAC kit. The kit contains four red
security frames, four gray port blocking security caps,
unlocking key and instructions. The red security frame must
first be attached to each port that is to be secured.
1. First orient the red security frame so that the cable
locking tabs of both the frame and the switch are
aligned.
2. Insert the four mounting feet of the security frame into
the pre-punched holes around the switch port and push
until the frame snaps into place with an audible click.
3. Inserted cables or gray port blocking security caps are
now locked into place. Instructions for using the key to
unlock the cables or security caps are included in the
kit.
7 Switching Characteristics
Store and Forward
All data telegrams received by the switch are saved and
their validity checked. Invalid or faulty data packets
(> 1522 bytes or CRC errors) and fragments
(< 64 bytes) are rejected. Valid data telegrams are
forwarded by the switch. The switch always forwards
the data using the data transmission speed that is used
in the destination network segment.
Multi-Address Function
The switch independently learns the addresses for
termination devices, which are connected via a port, by
evaluating the source addresses in the data telegrams.
Only packets with unknown addresses, with a source
address of this port or with a multicast/broadcast
address in the destination address field are forwarded
via the corresponding port. The switch can store
addresses in its address table with an aging time of
5 minutes. This is important when more than one
termination device is connected to one or more ports. In
this way, several independent subnetworks can be
connected to one switch.
Quality of Service (QoS): IEEE 802.1P/Q
The FL SWITCH SFN… switches are capable of
reading Ethernet packets that have already been
assigned a priority level by a managed switch. In cases
of heavy traffic, packets with a priority level between 4

Once attached, the security frames are
permanently mounted and cannot be removed.
A restart deletes the entire address table.
