Dust and Particles
Fans cool power supplies and system components by drawing in room temperature air and exhausting 
heated air out through various openings in the chassis. However, fans also ingest dust and other particles, 
causing contaminant buildup in the system and increased internal chassis temperature. A clean operating 
environment can greatly reduce the negative effects...

NoteTo predict and remedy strong EMI, you may also need to consult experts in radio frequency interference 
(RFI).
If you use twisted-pair cable in your plant wiring with a good distribution of grounding conductors, the 
plant wiring is unlikely to emit radio interference. If you exceed the recommended distances, use a 
high-quality twisted-pair cable with one ground conductor...

Besides these appliances, the greatest threats to a system power supply are surges or blackouts that are 
caused by electrical storms. Whenever possible, turn off the system and any peripherals, and unplug 
them from their power sources during thunderstorms. If a blackout occurs—even a temporary 
one—while the system is turned on, turn off the system immediately and disconnect it...

NoteIn all situations, grounding practices must comply with Section 250 of the National Electric Code (NEC) 
requirements or local laws and regulations. A 6 AWG grounding wire is preferred from the chassis to the 
rack ground or directly to the common bonding network (CBN). The equipment rack should also be 
connected to the CBN with 6 AWG grounding wire.

Maintaining Safety with Electricity
When working on electrical equipment, follow these guidelines:
Do not work alone if potentially hazardous conditions exist anywhere in your work space.
Never assume that power is disconnected from a circuit; always check the circuit before working on 
it.
Look carefully for possible hazards in your work area, such as damp floors, ungrounded...

Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) damage, which can occur when modules or other FRUs are improperly 
handled, results in intermittent or complete failures. Modules consist of printed circuit boards that are 
fixed in metal carriers. Electromagnetic interference (EMI) shielding and connectors are integral 
components of the carrier. Although...

b.If you are using an ESD wrist strap that is equipped with an alligator clip, attach the alligator clip 
directly over the head of the system ground lug screw or to the system ground lug barrel.

Power Requirements
When preparing your site for the switch installation, follow these requirements:
In systems configured with two power supplies, connect each of the two power supplies to a separate 
input power source. If you fail to do this, your system might be susceptible to total power failure 
due to a fault in the external wiring or a tripped circuit breaker.
To prevent...

For International:
–Circuits should be sized according to local and national codes.
If you are using a 200/240 VAC power source in North America, the circuit must be protected by a 
two-pole circuit breaker.
The source AC outlet must be within 6 feet (1.8 meters) of the system and should be easily 
accessible.
The AC power receptacles used to plug in the chassis must be the...
