Examining The Installation Site - HP 12500 Series Installation Manual

Examining the installation site

The HP 12500 Routing Switch Series can only be used indoors. To ensure that the switch works properly
and to prolong its service lifetime, the installation site must meet the following requirements:
Weight support
Make sure the floor can support the total weight of the rack, chassis, cards, power supplies, and all other
components. Additionally, the floor loading plan must also consider system expansion, such as adding
more cards.
Temperature
CAUTION:
If condensation appears on the switch when you move it to a high-temperature environment, dry the switch
before powering it on to avoid short circuits.
To ensure the normal operation of the switch, make sure the room temperature meets the requirements
described in
