Installing the Switch
Installation Procedures
Port Type Cable Type
Gigabit-SX Multimode fiber-optic cables fitted with LC
(on Gigabit-SX-LC connectors
mini-GBIC)
Gigabit-LX Single-mode fiber-optic cables fitted with LC
(on Gigabit-LX-LC connectors.
mini-GBIC)
The multimode cables specified for the Gigabit-
SX mini-GBIC may also be used, but a mode-
conditioning patch cord may be needed — see
"Mode Conditioning Patch Cord for Gigabit-LX"
on page B-3
Gigabit-LH The same single-mode fiber-optic cables as for
(on Gigabit-LH-LC Gigabit-LX.
mini-GBIC)
Note:
Gigabit-LH - Between the transmit and receive ends of the cable, at least 5db of attenuation is required for a reliable
connection. This is equivalent to 20Km of the fiber-optic cable. For distances less than 20Km, you must add attenuators
to bring the total attenuation to at least 5db. Most cable vendors carry attenuators.

Installation Location - Before installing the switch, plan its location and
orientation relative to other devices and equipment:
• In the front of the switch, leave at least 7.6 cm (3 inches) of space for
the twisted-pair and fiber-optic cabling.
• In the back of the switch, leave at least 3.8 cm (1 1/2 inches) of space
for the power cord.
• On the sides of the switch, leave at least 7.6 cm (3 inches) for cooling.
Length Limits
220 meters to 550 meters depending on the
cable used. See "Fiber-Optic Cables" on
B-2 for more information.
• single-mode cable = 10 kilometers
• multimode cable = 550 meters
• 70 kilometers
