62 Important safety instructions
The Cabinet system and Chassis system support fiber-optic cable
interconnection between system cabinets or between system chassis using
the following equipment:
• NTDK84 10 m (33 ft) Dual-port Fiber Expansion daughterboard
(multimode plastic fiber-optic cable)
• NTDK22 10 m (33 ft) Fiber Expansion daughterboard (plastic fiber-optic
cable)
• NTDK23 10 m (33 ft) Fiber Receiver card (plastic fiber-optic cable)
• NTDK24 3 km (1.8 mi) Fiber Expansion daughterboard (Multimode
glass fiber-optic cable)
• NTTK02 Dual-port IP Expansion daughterboard
• NTTK01 Single-port IP Expansion daughterboard
• NTDK85 3 km (1.8 mi) Dual-port Fiber Expansion daughterboard
(Multimode glass fiber-optic cable)
• NTDK25 3 km (1.8 mi) Fiber Receiver card (Multimode glass fiber-optic
cable)
• NTDK79 3 km (1.8 mi) Fiber Expansion daughterboard (Single Mode
glass fiber-optic cable)
• NTDK80 3 km (1.8 mi) Fiber Receiver card (Single Mode glass
fiber-optic cable)
Note: Fiber-optic cable is the only type of interconnection cable
supported on a fully expanded Chassis system.
The following safety precautions must be followed when handling fiber
equipment:
• All persons handling fiber expansion daughterboards and fiber receiver
cards must be Electrostatic Discharge (ESD) protected. A wrist strap
provided with the cabinet also must be worn when handling fiber-optic
cables to prevent damage caused by static electricity.
• Always ensure the fiber-optic cable is routed out of the way of any traffic
through the premises.
• Never staple or bend the fiber-optic cable at an extreme angle. Do not
exceed the minimum 90¡ soft bend radius of 35 mm (1.5 in.).
Note: A conduit is not required for routing fiber-optic cable
between cabinets or chassis. However, if you require a conduit for
identification or other reasons, use a conduit measuring a minimum
of 25 mm (1 in.) in diameter.
