Radio and Antennas

BR200-WP routers have a 3x3 dual-band 2.4/5 GHz radio that supports IEEE 802.11a/b/g/n and three
embedded antennas with diversity.

Ethernet and Console Ports

There are four 10/100/1000-Mbps Ethernet RJ-45 LAN ports (ETH 1 through ETH 4). These ports are compatible
with 10/100/100Base-T/TX and automatically negotiate half- and full-duplex connections with the
connecting device. These ports are auto-sensing and adjust to straight-through and cross-over Ethernet
cables automatically.
The pin assignments in the Ethernet ports follow the TIA/EIA-568-B standard (see
ports accept standard types of Ethernet cable—cat3, cat5, cat5e, or cat6. Because the ports have
autosensing capabilities, the wiring termination in the Ethernet cable can be either straight-through or
cross-over.
For PoE ports, especially with 803.2at, Aerohive recommends using cat5 or cat 6 Ethernet cable.
Use the RJ-45 console port to make a serial connection between your management system and the router.

Description
The Type-A USB 2.0 port (backward compatible with USB1.1) allows you to connect
a wireless 3G/4G USB modem to serve as a backup WAN connection. For locations
where an Ethernet connection to the WAN is not possible, you can use the USB
modem as the primary (and only) interface to the WAN.
For specific information about the modems supported for the BR200 series routers
and configuration settings, refer to HiveManager Help.
You can physically secure the router by attaching a lock and cable (such as a
®
Kensington notebook lock). Wrap the cable around an immovable object like a
table or desk, and then insert the lock into the built-in security slot in the device.
