Electrical safety
• Carefully examine your work area for possible hazards such as moist floors, ungrounded power
extension cables, or missing safety grounds.
• Locate the emergency power-off switch in the room before installation. Shut off the power
immediately if an accident occurs.
• Unplug all the external cables (including power cables) before moving the chassis.
• Do not work alone when you operate the switch with the switch powered on.
• Always check that the power has been disconnected when you perform operations that require the
switch to be powered off.
Laser safety
W
ARNING!
Do not stare into any fiber port when the switch is powered on. The laser li
g
ht emitted from the optical fiber
might hurt your eyes.
• Before you disconnect the fiber connector, execute the shutdown command in interface view to
disable the optical source.
• Install the dust covers to the optical fiber connector to avoid connector damage.
Examining the installation site
The switch can only be used indoors. To ensure normal operation and a long lifespan for your switch, the
installation site must meet the requirements in this section.
Temperature and humidity….
Maintain appropriate temperature and humidity in the equipment room.
• Continuous high relative humidity can cause poor insulation, electricity creepage, and metal
corrosion and can change the mechanical property of materials.
• Continuous low relative humidity can cause washer contraction and ESD and introduce problems
such as loose captive screws and circuit failure.
• High temperature can accelerate the aging of insulation materials and significantly lower the
reliability and lifespan of the switch.
To ensure correct operation of the switch, the equipment room must meet the temperature and humidity
requirements listed in Table 1.
Table 1 Temperature/
humidity requirements in the equipment room
Temperature Relative humidity
0°C to 45°C (32°F to 113°F) 5% to 95%, noncondensing
3
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.
Table 2 Dust concentration limit in the equipment
room
Substance Concentration limit (particles/m
3
)
Dust particles
≤ 3 x 104
(No visible dust on desk in three days)
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 Table 3.

Power
Perform the following tasks to meet the power requirements:
1. Calculate the system power consumption.
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.
2. Verify that the power system at the installation site meets the requirements of the power supplies,
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.

Figure 1 Airflow through the switch chassis
ESD prevention
To prevent electrostatic discharge (ESD), follow these guidelines:
• Ground the switch properly. For how to ground your switch, see "Grounding the switch."
• T
ake dust-proof measures for the equipment room. For more information, see "Cleanness."
• Maintain the humidity and temperature at a proper level. For more information, see "Temperature
and h
umidity."
• Always wear an ESD-preventive wrist strap. Make sure the wrist strap makes good skin contact and
is well grounded when installing the transceiver module.
NOTE:
The ESD-preventive wrist strap is not provided with the switch. Order it yourself.
To attach an ESD-preventive wrist strap:
1. Wear the wrist strap on your wrist.
2. Lock the wrist strap tight around your wrist to maintain good contact with the skin.
3. Secure the wrist strap lock and the alligator clip lock together.
4. Attach the alligator clip to the rack.
5. Make sure the rack is well grounded.

All electromagnetic interference (EMI) sources, from either outside or inside of the switch and application
system, adversely affect the switch in a conduction pattern of capacitance coupling, inductance coupling,
electromagnetic wave radiation, or common impedance (including grounding system) coupling. To
prevent EMI, follow these guidelines:
• Use a socket with three pins and PE wire to prevent interference from the power grid.
• Use a grounding system and a lightning protection system for the switch separate from those for
other electric equipment, and keep them far away as possible.
• Keep the switch far away from radio transmitting stations, radar stations, and high-frequency
devices.
• Use electromagnetic shielding, for example, shielded interface cables, when necessary.
Lightning protection
To better protect the switch from lightning, follow these guidelines:
