DGS-1510/ME Series Metro Ethernet Switch Hardware Installation Guide

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

sudden stops and uneven surfaces.

CAUTION: Risk of explosion if the battery is replaced by an incorrect battery type. Dispose of

used batteries according to the instructions.

ATTENTION: Risque d'explosion si la batterie est remplacée par un type incorrect. Jetez les piles

usagées selon les instructions.

注意：

如果更換不正確之電池型式會有爆炸的風險，請依製造商說明書處理用過之電池。

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 could 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.

• Always load the rack from the bottom up, and load the heaviest item in the rack first.

• Make sure that the rack is level and stable before extending a component from the rack.

• Use caution when pressing the component rail release latches and sliding a component into or out of a rack;

the slide rails can pinch your fingers.

• After a component is inserted into the rack, carefully extend the rail into a locking position, and then slide the

component into the rack.

• Do not overload the AC supply branch circuit that provides power to the rack. The total rack load should not

exceed 80 percent of the branch circuit rating.

• Ensure that proper airflow is provided to components in the rack.

• Do not step on or stand on any component when servicing other components in a rack.

NOTE: A qualified electrician must perform all connections to DC power and to safety grounds. All

electrical wiring must comply with applicable local or national codes and practices.

CAUTION: Never defeat the ground conductor or operate the equipment in the absence of a

suitably installed ground conductor. Contact the appropriate electrical inspection authority or an

electrician if uncertain that suitable grounding is available.

CAUTION: The system chassis must be positively grounded to the rack cabinet frame. Do not

attempt to connect power to the system until grounding cables are connected. Completed power

and safety ground wiring must be inspected by a qualified electrical inspector. An energy hazard

will exist if the safety ground cable is omitted or disconnected.
