Installation manual

1 Avoid the following situations:
a Attaching UTP cable to AC power cables
b Routing UTP cable near antennas, such as a ham radio antenna
c Routing UTP cable near equipment that could exhibit RF interference, such as ARC welding
equipment
d Routing UTP cable near electrical motors
e Routing UTP cable near air conditioner units
f Routing UTP cable near electrical transformers
2 In areas or applications where these situations cannot be avoided, use fiber optic cabling or shielded
twisted pair cabling (STP).
Meeting Power Requirements
The following sections contain recommendations for planning your connections for your Extreme
Networks equipment.
Planning Power Supply Requirements
Follow these recommendations when you are planning your connections for your Extreme Networks
equipment.
1 Place the equipment in an area that accommodates the power consumption and component heat
dissipation specifications.
2 Be sure that your power supply meets the site DC power or AC power requirements of the network
equipment.
3 When you connect power to installed equipment, do not make this connection through an extension
cord or power strip.
4 Connect half of the power supplies to one power source. Connect the others to a separate
independent power source.
If a power source fails, it will affect only the power supplies to which it is connected. If all
BlackDiamond X series power supplies are connected to a single power source, the entire chassis is
vulnerable to a power source failure.
5 In regions that are susceptible to electrical storms, we recommend that the AC/commercial power
should be conditioned and that appropriately sized/rated surge arrestor/suppression devices be
installed/utilized.
For additional information on power supplies, see Power Supplies for BlackDiamond X Series Switches
on page 119.
