Installing the Switch

Installation Procedures

Installing the Switch

■

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, 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

µ

m cable:

– 160 MHz*km = 220 meters
– 200 MHz*km = 275 meters

• 50

µ

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
