Chapter 2 Switch Installation
• For 10/100 ports and 10/100/1000 ports, the cable length from a switch
to an attached device cannot exceed 100 m (328 ft).
• The fiber-optic cable length from a switch to an attached device cannot
exceed the distance specified in Appendix C .
• For maximum noise immunity, shielded cables must be used on the RJ45
uplink ports (Gi1/1 and Gi1/2) on these switches:
– 1783-BMS06TGL
– 1783-BMS06TGA
– 1783-BMS10CGL
– 1783-BMS10CGA
– 1783-BMS10CGN
– 1783-BMS10CGP
– 1783-BMS12T4E2CGNK
– 1783-BMS12T4E2CGP
– 1783-BMS12T4E2CGL
– 1783-BMS20CGL
– 1783-BMS20CGN
– 1783-BMS20CGP
– 1783-BMS20CGPK
• Temperature surrounding the unit does not exceed 60 °C (140 °F).
• Clearance to front and rear panels meets these conditions:
– Front-panel status indicators can be easily read.
– Access to ports is sufficient for unrestricted cabling.
– Front-panel direct current (DC) power connectors and the alarm relay
connector are within reach of the connection to the DC power source.
• Cabling is away from sources of electrical noise, such as radios, power lines,
and fluorescent lighting fixtures.
• Connect the unit to only a Class 2 DC power source.
IMPORTANT When the switch is installed in an industrial enclosure, the
temperature within the enclosure is greater than normal room
temperature outside the enclosure.
The temperature inside the enclosure cannot exceed 140 °F (60 °C), the
maximum ambient enclosure temperature of the switch.
ATTENTION: Do not wire more than 1 conductor on any single terminal.
