Cleanness

Dust buildup on the chassis can result in electrostatic adsorption, which causes poor contact of metal
components and contact points, especially when indoor relative humidity is low. In the worst case,
electrostatic adsorption can cause communication failure. To ensure correct operation, the equipment
room must meet the dust concentration requirements listed in
Table 2 Dust concentration limit in the equipment room
Substance
Dust particles
NOTE:
Dust particle diameter ≥ 5 μm
To eliminate corrosion and premature aging of components, the equipment room must also meet limits on
salts, acids, and sulfides, as shown in

Power

Perform the following tasks to meet the power requirements:
Calculate the system power consumption.
1.
The system power consumption varies by the number of PDs (IP phones, WLAN APs, security, and
Bluetooth APs) connected to the switch. For an HP 830 24-port PoE+ unified wired-WLAN switch,
the maximum power that each Ethernet port supplies to the PDs is 30 W. For the HP 830 24-port
PoE+ unified wired-WLAN switch, the maximum system power consumption is 370 W for AC
power supply, and the maximum system power consumption is 720 W (30 W × 24 ports) for RPS
power supply. The output power for the RPS power supply cannot be smaller than 740 W.
Verify that the power system at the installation site meets the requirements of the power supplies,
2.
including the input method and rated input voltage.

Cooling

The switch uses left-to-right airflow for heat dissipation. Plan the installation site for adequate ventilation.
• HP recommends that you leave a minimum of 10 cm (3.94 in) of clearance around the air vents.
Make sure the rack is well ventilated.
