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,
except if the switch is installed in an open EIA/TIA rack.
Fiber Optic Cables
Gigabit-SX
(on Gigabit-SX-LC
mini-GBIC) Multimode fiber-optic cables designed for
Gigabit Ethernet: 62.5/125
µ
m or 50/125
µ
m
(core/cladding) diameter, 850 nm, low metal
content, graded-index cables, fitted with LC
connectors. The cables must comply with the
ITU-T G.651 and ISO/IEC 793-2 Type A1b or A1a
standards.
• 62.5

m cable:
– 160 MHz*km = 220 meters
– 200 MHz*km = 275 meters
• 50

m cable:
– 400 MHz*km = 500 meters
– 500 MHz*km = 550 meters
Gigabit-LX
(on Gigabit-LX-LC
mini-GBIC) Single-mode fiber-optic cables designed for
Gigabit Ethernet: 9/125
µ
m (core/cladding)
diameter, 1310 nm, low metal content cables,
fitted with LC connectors. The cables must
comply with the ITU-T G.652 and ISO/IEC 793-2
Type B1 standards.
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
for more information.
• single-mode cable = 5 kilometers
• multimode cable = 550 meters
Gigabit-LH
(on Gigabit-LH-LC
mini-GBIC) Single-mode fiber-optic cables designed for
Gigabit Ethernet and fitted with LC connectors. • single-mode cable = 70 kilometers
