7850 Extension Switch Hardware Installation Guide
DANGER
Batteries used for RTC/NVRAM backup are not located in operator-access areas. There is a risk of explosion
if a battery is replaced 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 that 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.
Laser Precautions
DANGER
All fiber-optic interfaces use Class 1 lasers.
