USBModem Port
The USB modem port (backward compatible with USB1.1) allows you to connect a wireless
3G/4G USB modem to serve as a backup WAN connection.
If you use a USBLTEmodem, you must use 802.3at standard PoE and PSE.
The port is protected by a port cover, as shown in the hardware components illustration
above. To access the port, remove the screw that secures the cover in place. To protect
the port, keep the cover in place when the port is not in use. For additional security, when
you are not using the port, you can secure it with one of the security screws that ship with
the device.
If you use the security screw, you will need a spanner insert bit for size #6 security
screws and a driver handle that will accept the bit. These bits are available from
Aerohive in sets of three for AP121, AP141, AP230, AP250, AP330, AP350, AP370,
and AP390 models (AH-ACC-SEC-BIT-330-AP350-3PK).
Antennas
The AP250 has nine internal antennas:
• Five single-band 5 Ghz antennas
• Three dual-band 2.4 GHz/5 GHz antennas
•One
BLE antenna.
Locking Slot
When mounting the AP on a ceiling track or flat surface, you can secure it to the track using
a Kensington ® lock in the lock slot or using a security bracket (shipped separately). See
"Securing the AP250".
Hardware Specifications
Understanding the range of specifications for these APs is necessary for optimal deployment and
device operation. The following specifications describe the physical features and hardware
components, PoE electrical requirements, and the temperature and humidity ranges in which the
devices can operate.
