Electrical Surge Warning

In order to help protect equipment against electrical surges please take note of the following
recommendations and guidelines:
Earth grounding of all devices is fundamental to ensure long term reliability.
1
• All electrical equipment must be installed by a qualified, licensed electrician.
Every power supply that is connected to building power should be earth grounded.
•
Earth grounding for the power cable, should be verified to be 0.01 ohm or less.
•
• Each switch should be grounded to same earth ground as the power supply.
Each powered device, such as an AP or camera, should be connected to earth ground.
•
Each surge suppression device should be connected to earth ground.
•
Shielded cables (STP) offer some minimal level of additional protection over unshielded Ethernet
2
cables (UTP) but the use of a surge protector is still recommended.
It is suggested to use STP Cat5e or better for 1Gbps Ethernet switches for any outdoor application or
•
applications where Ethernet cables come in close proximity to alternating current conductors.
Always install cables according to manufacturer requirements.
•
For any connections where integrity of the cabling within a building ground is questionable (i.e outdoor
3
connections), copper Ethernet ports must be connected with an appropriate surge protection device, inline,
between the PSE and PD per the manufacturer's recommendations for connection and grounding.
Caution should be taken for any cable connected to any outdoor device, not only on the device ground-
4
ing, but to ensure that any outdoor device cables that could carry surge currents, do not pass those surge
currents to upstream Ethernet switches.
Caution - Category 5e, Category 6, and Category 6a cables can store large amounts of static electricity
5
due to the dielectric properties of their construction materials in addition, this build up of electricity could
lead to a Cable Discharge Event (CDE). A CDE can occur due to the differential in charges on the cable
and the equipment it's being connected to. It is recommended that installers momentarily ground all
copper Ethernet cables (especially in new cable runs) to a suitable and safe earth ground before connect-
ing them to the port.
Note. Failure to follow the above recommendations could result in voiding the warranty of the affected
ALE product.

Unpacking and Installing the Switch

To protect your switch components from damage, read all unpacking recommendations and instructions
carefully before beginning.
Unpack your chassis as close as possible to the location where it will be installed.
