Using the FL SEC PAC Kit for Port Security
“conductors” are typically locked together through the
connector.
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.
Once attached, the security frames are
permanently mounted and cannot be removed.
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.
