Laser safety

WARNING!
Do not stare into any optical port or view directly with non-attenuating optical instruments when the switch
has power. The laser light emitted from the optical fiber may hurt your eyes.
The HP FlexFabric 12900 switches are Class 1 laser products.

Examining the installation site

The HP FlexFabric 12900 switches must be used indoors. To ensure the normal operation and long
service life 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 to a rack, make sure the slide rails can support the total weight of the
switch and its accessories (cards, power supplies, and transceiver modules). When the switch is installed
with all accessories, its maximum weight is 200 kg (440.92 lb). HP recommends that you order the HP
X421 A-Series Chassis Universal 4-Post Rack Mounting Kit (JC665A), which supports a weight up to 300
kg (661.38 lb).
Additionally, the floor and slide rail loading plan must also consider system expansion, such as adding
more cards. For more information, see
