Handling Safety - HP FlexFabric 12900E series Installation Manual

•
Remove all external cables, including power cords, before moving the chassis.
•
Do not work alone when the switch has power.
•
Always verify that power has been disconnected from a circuit.

Handling safety

CAUTION:
Do not hold the handle of a fan tray, a power supply, or a card, or the air vents of the chassis to
move the switch. Any attempt to move the switch with these parts might cause equipment damage
and even bodily injury.
When you move the switch, follow these guidelines:
•
Remove power supplies, cards, and all external cables, including the power cords, before
moving the chassis.
•
Hold the chassis handles on the two sides to lift the chassis.
•
Cooperate with a minimum of four people to move the chassis. Hewlett Packard Enterprise
recommends that you use a mechanical lift, such as forklift truck, to move the chassis.
•
Lift and put down the chassis slowly and never move suddenly.
ESD prevention
To prevent the electric component from being damaged by electrostatic discharge (ESD), follow
these guidelines:
•
Ground the switch reliably. For how to ground your switch, see
•
Always wear an ESD wrist strap and make sure it is reliably grounded when installing FRUs.
For how to use an ESD wrist strap, see
•
Hold a PCB by its edges. Do not touch any electronic components or printed circuit.
•
Put cards away in antistatic bags for future use.
Laser safety
WARNING!
Do not stare into any fiber port or view directly with non-attenuating optical instruments when the
switch has power. The laser light emitted from the fiber port might hurt your eyes.
The switch is a Class 1 laser product.
Examining the installation site
The switch must be used indoors. To ensure correct operation and long lifespan of your switch, the
installation site must meet the requirements in this section.
Weight support
Make sure the floor can support the total weight of the rack, chassis, cards, power supplies, and all
other components. To mount the switch in a rack, make sure the slide rails can support the total
weight of the switch and its accessories (cards, power supplies, and transceiver modules).
