V At each drop, allow sufficient cable for a service loop and strain

reliefs.

V At each drop, provide a service loop to allow the cable to be

connected and disconnected from the network device without strain

on the cable. A service loop of 6 in (15 cm) minimum radius is

adequate for most installations.

V Two cable ties are provided with each cable connector for use as

strain reliefs. Use one of these at each drop to secure the cable to a

panel or other stable assembly, to prevent the cable’s weight from

pulling on the connector. The other strain relief will be used on the

connector.

V Use additional ties as required to secure the cable from flexing or

other damage in areas of mechanical motion devices and traffic.

V If you are installing cables for a dual-cable network, the two cables

should be identified as Cable A and Cable B.

V Make sure that each cable is properly marked so that it can be

positively identified as Cable A or Cable B over the entire

end-to-end length of the network.
