The SC connectors have a square interface and the

“conductors” are typically locked together through the

connector.

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.

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.
