Aruba MST200 Wireless Mesh Router
Installation Guide
The Aruba AirMesh MST200 is a resilient, environmentally hardened, outdoor rated, single-radio IEEE
802.11 a/n wireless mesh access router. This router is part of Aruba’s comprehensive wireless network
solution.The MST200 delivers high-performance outdoor wireless mesh connectivity for remote locations
and devices such as IP video surveillance cameras, remote sensors, and digital signage. The MST200 is also
ideal for point-to-point outdoor mesh links between buildings and remote sites.
MST200 requires the Aruba MeshOS operating system.
There are two versions of the MST200, which mainly differ in the way they receive power.
MST2HP: Power over Ethernet+ (PoE+) powered (802.3at)
MST2HAC: AC powered (100 - 240 VAC)
The MST2HAC can function as a Power Sourcing Equipment (PSE) device by providing power through its Ethernet
port in compliance with the IEEE 802.3af standard.

Quick Start Guide
The MST200 does not ship with any power cables; these are available as accessories and should be ordered
separately.
Inform your supplier if there are any incorrect, missing, or damaged parts. If possible, retain the carton, including
the original packing materials. Use these materials to repack and return the unit to the supplier if needed.

USB Console Interface
A USB serial console port is provided for connection to a terminal, allowing direct local management. Use
the included USB console cable to connect to the router. You can download the necessary driver for USBUART adapter from support.arubanetworks.com under the Tools & Resources tab.
Use the following settings to access the terminal:

The baud rate setting depends on the manufacture date of the MST200 (before or after March 2012) and the
Serial Number (14 characters or 9 characters). The table above lists all the SKUs for MST200 along with the
corresponding baud rate.
Power Interface
The type of power interface on the MST200 depends on the model that you have purchased.
MST2HP: This version does not include a power interface since it is only powered by PoE+ (802.3at).
MST2HAC: One AC power connector.
Ethernet Interface
The MST200 is equipped with a 10/100/1000Base-T Gigabit Ethernet port for wired network connectivity. On
the MST2HP, this port also supports IEEE 802.3at Power over Ethernet (PoE), accepting 48 VDC as a
standards-defined powered device (PD) from a power sourcing equipment (PSE) device, such as a PoE
midspan injector. Inversely, the MST2HAC can act as a PSE device to provide IEEE802.3af PoE power to
devices such as a video camera, connected to the Ethernet port.

RSSI for Radio 0
Pressure Equalization Port
The Pressure Equalization port allows air exchange between the MST200 and environment in a controlled
way that doesn’t allow water to get into the MST200. This balances the pressure and humidity inside and
outside the MST200.
Grounding Point
Always remember to protect your MST200 by installing grounding lines. The ground connection must be
completed before connecting power to the MST200 enclosure. Ensure that the resistance is less than 5 ohm
between the ground termination point and the grounding tier and the cross section of the grounding cable
should be no less than 6 square mm.
MST2HP LED Status Indicators
The MST2HP includes visual indicators for power, link, and radio status. Additionally, each radio has a fourLED array that indicates received signal strength (RSSI).
The RSSI LED indicators represent varying degrees in the RSSI level. The absence of a signal is indicated by no
LED response. All four LEDs are active and lit is an indication of full signal strength.

Starting with MeshOS 4.5, you can turn off the LEDs in the MST200 devices using the WMI and CLI. The LEDs are
enabled by default. This option may be used to disable the LED lights in a MST200 device that is mounted in an
elevated place on the city streets or residential areas, to avoid unwanted attention or disturbance. This feature turns
off only the LED lights that indicate the software status, for example the RF. The LEDs that indicate the hardware
status, for example Power, P/S, POE, and ETH, cannot be turned off using this feature. For additional details, refer
to the Aruba MeshOS User Guide and the Aruba MeshOS Command Reference Guide.
