Cisco Systems 274 Manuale Utente

Observe power strip ratings. Make sure that the total ampere rating of all 
products plugged into the power strip does not exceed 80 percent of the power 
strip ampere ratings limit.

Do not use appliance or voltage converters or kits sold for appliances with 
your product.

To help protect your system components from sudden, transient increases and 
decreases in electrical power, use a surge suppressor, line conditioner, or 
uninterruptible power supply (UPS).

Position cables and power cords carefully; route cables and the power cord 
and plug so that they cannot be stepped on or tripped over. Be sure that 
nothing rests on your system components’ cables or power cord.

Do not modify power cables or plugs. Consult a licensed electrician or your 
power company for site modifications. Always follow your local or national 
wiring rules.

To help ensure proper cooling and system reliability, make sure that the following 
occurs: 

Each of the drive bays has either a drive or a filler panel installed.

For rack configurations, make sure that space is available around the 
appliance to enable the cooling system to work properly. See the 
documentation that comes with the rack for additional information.

The appliance cover is in place during normal operation.

The air baffle cover over the microprocessors remains closed during normal 
operation.

The air baffle is installed between the fans and the power supply.

A removed hot-swappable drive is replaced within 2 minutes of removal.

Cables for optional adapters are routed according to the instructions provided 
with the adapters.

A failed fan is replaced within 48 hours.

The appliance is powered down and the power cords are disconnected before 
you open the air baffle cover.
