Examining the installation site
The H3C S12500 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 Table 8 .
Table 8 Temperature requirements
Temperature Range
Operating temperature
• Long term:
—0°C to 40°C (32°F to 104°F)
• short term:
–10°C to +50°C (14°F to 122°F) (no more than 96 hours of continuous
operation in less than 15 days in one year)
Storage temperature –40°C to +70°C (–40°F to +158°F)
Humidity
• Lasting high relative humidity can cause poor insulation, electricity creepage, mechanical property
change of materials, and metal corrosion.
• Lasting low relative humidity can cause washer contraction and ESD and bring problems including
loose captive screws and circuit failure.
Maintain appropriate humidity in your equipment room, as described in Table 9 .
