Lifting And Weight-Related Precautions - Brocade Communications Systems G620 Hardware Installation Manual

DANGER
Batteries used for RTC/NVRAM backup are not located in operator-access areas. There is a risk of explosion if a battery
is replace by an incorrect type. Dispose of used components with batteries according to local ordinance and regulations.
CAUTION
Use a separate branch circuit for each power cord, which provides redundancy in case one of the circuits fails.
CAUTION
Ensure that the device does not overload the power circuits, wiring, and over-current protection. To determine the
possibility of overloading the supply circuits, add the ampere (amp) ratings of all devices installed on the same circuit as the
device. Compare this total with the rating limit for the circuit. The maximum ampere ratings are usually printed on the
devices near the input power connectors.
CAUTION
The power supply switch must be in the off position when you insert the power supply into the chassis. Damage to the
switch can result if a live power supply is installed.
CAUTION
Carefully follow the mechanical guides on each side of the power supply slot and make sure the power supply is properly
inserted in the guides. Never insert the power supply upside down.
NOTE
Device control processors and management modules may contain batteries for RTC or NVRAM backup. Dispose of
components containing batteries as required by local ordinances and regulations.

Lifting and weight-related precautions

DANGER
Use safe lifting practices when moving the product.
DANGER
Mount the devices you install in a rack as low as possible. Place the heaviest device at the bottom and progressively place
lighter devices above.
DANGER
Make sure the rack housing the device is adequately secured to prevent it from becoming unstable or falling over.
CAUTION
Do not use the port cover tabs to lift the module. They are not designed to support the weight of the module, which can fall
and be damaged.
CAUTION
To prevent damage to the chassis and components, never attempt to lift the chassis using the fan or power supply handles.
These handles were not designed to support the weight of the chassis.
