•
Attaching UTP cable to AC power cables
•
Routing UTP cable near antennas, such as a ham radio antenna
•
Routing UTP cable near equipment that could exhibit RF interference, such as ARC welding
equipment
•
Routing UTP cable near electrical motors that contain coils
•
Routing UTP cable near air conditioner units
•
Routing UTP cable near electrical transformers
In areas or applications where these situations cannot be avoided, use fiber optic cabling or shielded
twisted pair cabling (STP).
Meeting Power Requirements
Observe the following requirements and precautions for powering your hardware.
Power Supply Requirements
Follow these recommendations when you plan power supply connections for the E4G series routers:
•
Place the equipment in an area that accommodates the power consumption and component heat
dissipation specifications.
•
Be sure that your power supply meets the site DC power or AC power requirements of the network
equipment.
•
When you connect power to installed equipment, do not make this connection through an extension
cord or power strip.
•
If your router includes more than one power supply, connect each power supply to a different,
independent power source.
If a power source fails, it will affect only the router power supply to which it is connected. If all router
power supplies are connected to a single power source, the entire router is vulnerable to a power
source failure.
•
In regions that are susceptible to electrical storms, we recommend that you plug your system into a
surge suppressor.
For power specifications for E4G series routers, see
Technical Specifications
on page 91.
Turning your unit on and off
Extreme Networks routers do not have a switch for turning power to the unit on and off.
Warning
Disconnecting the DC power cable from the DC power source must be done by a qualified,
licensed electrician.
•
For systems using an AC power supply, remove the wall plug from the electrical outlet to disconnect
the power to the router.
