Installing the Hardware Getting Started

Reliable Earthing
Reliable earthing of rack-mounted equipment should be maintained. Particular attention should be given
to supply connections other than direct connections to the branch (e.g., use of power strips).
OmniSwitch 6350 switches have the following general electrical requirements:
• Each switch requires one grounded electrical outlet for each power supply installed in the chassis.
• OmniSwitch 6350 switches offer both AC and DC power supply support.
• For switches using AC power connections, each supplied AC power cord is 2 meters (approx. 6.5
feet). Do not use extension cords.
Redundant AC Power. It is recommended that each AC outlet resides on a
separate circuit. With redundant AC power, if a single circuit fails, the switch’s
remaining power supplies (on separate circuits) can remain operational.
For switches using DC power, refer to the “DC Power Supply Connections” for more information.
Electrical Surge Warning
In order to help protect equipment against electrical surges please take note of the following
recommendations and guidelines:
1. Earth grounding of all devices is fundamental to ensure long term reliability.
• 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.
2. Shielded cables (STP) offer some minimal level of additional protection over unshielded Ethernet
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.
3. For any connections where integrity of the cabling within a building ground is questionable (i.e
outdoor 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.
