Chapter 3 Switch Installation (8- and 12-Port Switches) Statement 371-Power Cable and AC Adapter Preparing for Installation Caution To comply with the Telcordia GR-1089 Network Equipment Building Systems (NEBS) standard for electromagnetic compatibility and safety, connect the ethernet cables only to intrabuilding or nonexposed wiring or cabling. Caution To comply with the Telcordia GR-1089 NEBS standard, PoE or non-PoE 10/100/1000 Ethernet port cables that exit from either the left side or right side of the switch should be routed and tied to the nearest rack metal hardware. Note The grounding architecture of this product is DC-isolated (DC-I). Installation Guidelines When you determine where to place the switch, be sure to observe these requirements: • The operating environment is within the ranges listed in Appendix A, "Technical Specifications." • Airflow around the switch and through the vents is unrestricted. Allow at least 3 inches (7.6 cm) of clearance on all sides and ventilation openings, particularly if you stack the switches or place them side by side. • You have allowed at least 1.75 inches (4 cm) of clearance above each switch in the rack. • Clearance to front and rear panels is such that - You can easily read the front-panel indicators. - Access to ports is sufficient for unrestricted cabling. - The rear-panel power connector is within reach of an AC power receptacle. • Temperature around the unit does not exceed 113°F (45°C). If the switch is installed in a closed environment or in a multirack assembly, the temperature around it might be greater than normal room temperature. • The heat sinks and the bottom of the switch might be hot to the touch if the switch is operating at its maximum temperature 113°F (45°C) and is in an environment that exceeds normal room temperature (such as in a closet, in a cabinet, or in a closed or multirack assembly). • No other items are placed on the top of the switch. • The switch is not wall-mounted with its front panel facing up or sideways. According to safety regulations, wall-mount the switch with its front panel facing down to prevent airflow restriction and to provide easier access to the cables.

Switch Installation (8- and 12-Port Switches)
Preparing for Installation
Statement 371—Power Cable and AC Adapter
Caution
To comply with the Telcordia GR-1089 Network Equipment Building Systems (NEBS) standard for
electromagnetic compatibility and safety, connect the ethernet cables only to intrabuilding or
nonexposed wiring or cabling.
Caution
To comply with the Telcordia GR-1089 NEBS standard, PoE or non-PoE 10/100/1000 Ethernet port
cables that exit from either the left side or right side of the switch should be routed and tied to the nearest
rack metal hardware.
Note
The grounding architecture of this product is DC-isolated (DC-I).
Installation Guidelines
When you determine where to place the switch, be sure to observe these requirements:
•
The operating environment is within the ranges listed in
Appendix A, “Technical Specifications.”
•
Airflow around the switch and through the vents is unrestricted. Allow at least 3 inches (7.6 cm) of
clearance on all sides and ventilation openings, particularly if you stack the switches or place them
side by side.
•
You have allowed at least 1.75 inches (4 cm) of clearance above each switch in the rack.
•
Clearance to front and rear panels is such that
–
You can easily read the front-panel indicators.
–
Access to ports is sufficient for unrestricted cabling.
–
The rear-panel power connector is within reach of an AC power receptacle.
•
Temperature around the unit does not exceed 113°F (45°C).
If the switch is installed in a closed environment or in a multirack assembly, the temperature around
it might be greater than normal room temperature.
•
The heat sinks and the bottom of the switch might be hot to the touch if the switch is operating at
its maximum temperature 113°F (45°C) and is in an environment that exceeds normal room
temperature (such as in a closet, in a cabinet, or in a closed or multirack assembly).
•
No other items are placed on the top of the switch.
•
The switch is not wall-mounted with its front panel facing up or sideways. According to safety
regulations, wall-mount the switch with its front panel facing down to prevent airflow restriction
and to provide easier access to the cables.
