Usb Modem Port; Br200-Wp Poe Lan Ports - Aerohive Networks AP121 Hardware Reference Manual

USB Modem Port

BR200 devices can use a wireless USB modem for a WAN connection. The typical use of the USB modem is to
act as a backup to the ETH0/WAN interface; however, 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.
When using a wireless USB modem on a BR200 device you must connect it to an AC power source
instead of using PoE to power the device.
Aerohive currently supports the following USB modems:
• AT&T Momentum (Sierra Wireless Aircard 313U) to connect to the 3G wireless network
• AT&T Shockwave (Sierra Wireless USBConnect 308) to connect to the 3G wireless network
• Verizon Pantech UML290 to connect to the 4G (LTE) network
The international counterparts for the Momentum and Shockwave modems (the Sierra Wireless
Aircard 310U, 312U, and 320U) can also be used with these routers.
Before you can use a modem with an Aerohive device, you must first have the modem activated. You can
have this done in the store where you purchased the modem, or you can install software such as the Verizon
VZA Access Manager on your computer, connect the modem to the USB port on your computer, preferably
at the site where you plan to deploy the router to confirm that the modem is working properly and that there
is adequate wireless network coverage in your location.

BR200-WP PoE LAN Ports

On BR200-WP routers, the ETH1/PoE and ETH2/PoE ports can provide PoE (Power over Ethernet) to PDs
(powered devices) such as VoIP phones, wireless access points, and network cameras. These ports are
IEEE802.3af and IEEE802.3at PSE (power sourcing equipment) compliant, as described here:
• 802.3af PoE provides up to 12.95 W of DC power to each device (this rate reflects normal power loss
through the cables). 802.3af meets the power demands of PoE Class 0, 1, 2, and 3 devices.
• 802.3at PoE provides up to 25.5 W of DC power to each device (this rate reflects normal power loss
through the cables). 802.3at meets the power demands of PoE Class 4 devices.
The BR200-WP router balances PoE power output automatically. For example, if a device connected to ETH1
requires more power than the port can provide, and if ETH1 has the higher priority, ETH2 shuts down and shifts
all remaining power to ETH1. The router generates a log for every shutdown event.
802.3af is the default setting for both ports, but you can configure one port for 802.3at to support devices
that require more power than 802.3af can supply. By default, the ETH1 port running 802.3af has the higher
priority, but you can change the priority to determine which port shuts down to shift power to the other port.
If you configure one port for 802.3at, the remaining port will continue to supply 802.3af power rates unless it
needs to shut down and shift power. Only one PoE port can supply 802.3at power at a time.
If ETH1 is running 803.2at and you want to configure ETH2 for 803.2at, you must first reset ETH1 to
803.2af, and then set ETH2 to 802.3at.
