D-Link DGS-1024D [6/32] General precautions for rack mountable products

D-Link DGS-1016TL/DGS-1024TL Gigabit Ethernet Switch

Safety Instructions (continued)

• To help prevent an electric shock, plug the system and peripheral power cables into properly grounded

electrical outlets. These cables are equipped with three-prong plugs to help ensure proper grounding. Do

not use adapter plugs or remove the grounding prong from the cable. If you must use an extension cable,

use a 3-wire cable with properly grounded plugs.

• Observe extension cable and power strip ratings. Make sure that the total ampere rating of all products

plugged into the extension cable or power strip does not exceed 80 percent of the ampere ratings limit

for the extension cable or power strip.

• To help protect your system from sudden, transient increases and decreases in electrical power, use a

surge suppressor, line conditioner, or uninterruptible power supply (UPS).

• Position system cables and power cables carefully; route cables so that they cannot be stepped on or

tripped over. Be sure that nothing rests on any cables.

• Do not modify power cables or plugs. Consult a licensed electrician or your power company for site

modifications. Always follow your local/national wiring rules.

• When connecting or disconnecting power to hot-pluggable power supplies, if offered with your system,

observe the following guidelines:

– Install the power supply before connecting the power cable to the power supply.

– Unplug the power cable before removing the power supply.

– If the system has multiple sources of power, disconnect power from the system by

unplugging all power cables from the power supplies.

• Move products with care; ensure that all casters and/or stabilizers are firmly connected to the system.

Avoid sudden stops and uneven surfaces.

General Precautions for Rack-Mountable Products

Observe the following precautions for rack stability and safety. Also refer to the rack installation documentation

accompanying the system and the rack for specific caution statements and procedures.

Systems are considered to be components in a rack. Thus, "component" refers to any system as well as to various

peripherals or supporting hardware.

CAUTION: Installing systems in a rack without the front and side stabilizers

installed can cause the rack to tip over, potentially resulting in bodily injury under

certain circumstances. Therefore, always install the stabilizers before installing

components in the rack.

After installing system/components in a rack, never pull more than one component

out of the rack on its slide assemblies at one time. The weight of more than one

extended component could cause the rack to tip over and may result in serious

injury.

• Before working on the rack, make sure that the stabilizers are secured to the rack, extended to the floor,

and that the full weight of the rack rests on the floor. Install front and side stabilizers on a single rack or

front stabilizers for joined multiple racks before working on the rack.
