•Support cable using a cable manager mounted above connectors to avoid unnecessary weight on the cable bundles.

•Bundle cables using velcro straps to avoid damaging cables.

•Keep all ports and connectors free of dust.

•Unshielded Twisted Pair (UTP) cables can build up Electrostatic Discharge (ESD) charges when being pulled into a new installation. Before installing category 5 UTP cables, discharge ESD from the cable by plugging it into a port on a system that is not powered on.

•When required for safety and fire rating requirements, plenum-rated cable can be used. Check the local building codes to determine when it is appropriate to use plenum-rated cable, or refer to IEC standard 850.

Power Requirements

Power Supply

•The switch power supplies have a maximum power consumption requirement of 350W. Also ensure that the site meets all power supply requirements.

•Before installation and periodically after installation, check that the site is receiving clean power. Install a power conditioner if necessary.

•Be sure the site is properly grounded to avoid damage from lightning and power surges.

Uninterruptible Power Supply

Consider the following when selecting Uninterruptible Power Supply (UPS) equipment:

•The minimum amperage requirements for a UPS:

–Calculate VA (Volt-Amps): Locate the voltage and amperage requirements for each piece of equipment (usually located on a sticker on the back or bottom of the equipment). Multiply the numbers together to get VA.

–Add the VA from each piece of equipment together to find the total VA requirement. Then add 30% to determine the minimum amperage requirements for the UPS.

•Transition time (the time necessary for the UPS to transfer from utility power to full-load battery power).

•The longest potential time period the UPS might be required to supply backup power.

•Whether or not the UPS unit also provides online protection.
