Tsunami QB-8100 Series (100 Mbps/5 Mbps Models) Installation and Management Guide 17
2.1 Hardware Overview
The Tsunami QB-8100 Series (100 Mbps/5 Mbps Models) is a full-featured outdoor QuickBridge Endpoint that contains a high
power radio unit in plastic enclosure with dual polarized, high gain performance, integrated antenna.
The unit is designed to be mounted to a pole of 1.25” - 3” diameter (not included) using the supplied pole mount bracket
accessories (P/N 909-00001). An optional universal wall mounting bracket is also available from Proxim (P/N 77537); this kit is
designed to mount directly to a flat surface such as a roof, wall, or under an eave.
The QB-8100 unit has an ethernet port with auto-sensing 10/100 BASE-T with configurable Tx Modes and Speeds. The unit is
powered through Power-over-Ethernet via a PoE injector, and is equipped with bi-color LEDs on the ethernet connector.

2.1.1 Power-over-Ethernet
The QB-8100 unit is equipped with a Power-over-Ethernet (PoE) injector module which provides power through a PoE injector.
Using PoE injector, you can provide electricity and wired connectivity to the unit over a single Category5 cable.
• The PoE injector integrated module receives 48 VDC over a standard Cat5 Ethernet cable.
• Maximum power supplied to the QB-8100 unit is 19 Watts. The units typically draw less than 13.8 Watts.
• You must have a PoE injector connected to the network to use PoE. The injector is not a repeater and does not amplify
the Ethernet data signal.
• If connected to a PoE DC Injector and an AC power supply simultaneously, the radio draws power from PoE.
• The cable length between the PoE DC Injector and the radio should not exceed 100 meters (approximately 325 feet).
NOTE: The total length of cabling between the PC and the QuickBridge units cannot exceed 100 meters, which
includes both the cable from the PC to the power injector and the cable from the power injector to the QuickBridge
unit. Due to DC power requirements, the maximum cable length between the power injector and the QuickBridge
units is 75 meters.
