Aruba MSR4000 Wireless Mesh Router
The Aruba AirMesh MSR4000 is a resilient, environmentally hardened, outdoor rated, four-radio, dual-band
IEEE 802.11 a/b/g/n wireless mesh router. This outdoor mesh router is part of Aruba's comprehensive
wireless network solution. The MSR4000 delivers high-performance wireless mesh routing to outdoor
environments where wired connectivity is impractical or unavailable. The MSR4000 is ideal for deployment
in metropolitan and industrial areas, oil fields, mines, and shipping ports.
The MSR4000 requires the Aruba MeshOS operating system.
There are two versions of the MSR4000, which mainly differ in the way they receive power.
MSR4KP: Power over Ethernet (PoE+) powered
MSR4KAC: AC powered (100 - 240 VAC)
The MSR4KAC can function as a Power Sourcing Equipment (PSE) device by providing power through its Ethernet
port in compliance with the IEEE 802.3af standard.

Summary of Contents for Aruba MSR4000

  • Page 1: Package Contents

    The MSR4000 requires the Aruba MeshOS operating system. There are two versions of the MSR4000, which mainly differ in the way they receive power. MSR4KP: Power over Ethernet (PoE+) powered ...
  • Page 2 Quick Start Guide  The MSR4000 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.
  • Page 3 MSR4000 Hardware Overview The following section describes the hardware features of the MSR4000. Figure 1 MSR4KP Overview Antenna Interface 2 (Radio 2) Antenna Interface 1 (Radio 0) Antenna Interface 2 (Radio 1) Antenna Interface 1 (Radio 3) Antenna Interface 2 (Radio 3)
  • Page 4: Antenna Interface

    The MSR4000 is equipped with eight female N-type antenna interfaces; four on the top of the AP and four on the bottom. The interfaces are grouped into diversity pairs, marked R0 (Radio 0), R1 (Radio 1), R2 (Radio 2) and R3 (Radio 3).
  • Page 5: Ethernet Interface

    Always remember to protect your MSR4000 by installing grounding lines. The ground connection must be complete before connecting power to the MSR4000 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.

    Starting with MeshOS 4.5, you can turn off the LEDs in the MSR4000 devices using the WMI and CLI. The LEDs are enabled by default. This option may be used to disable the LED lights in a MSR4000 device that is mounted in an elevated place on the city streets or residential areas, to avoid unwanted attention or disturbance.

    Be sure there is enough clearance from buildings and that no building construction may eventually block  the path. For very long distance links, the curvature of the earth (20 cm per km) may need to be considered in the  calculation of relative heights. Aruba MSR4000 Wireless Mesh Router | Installation Guide...
  • Page 10: Antenna Height

    To avoid any obstruction along the path, the height of the object must be added to the minimum clearance required for a clear radio line of sight. Consider the following simple example, illustrated in Figure Aruba MSR4000 Wireless Mesh Router | Installation Guide...

  • Page 12: Weather Conditions

    An Aruba Lightning Arrestor, AP-LAR-1, must be installed on each antenna port for protection against lightning induced surges. Failure to use an AP-LAR-1 can void the warranty of an Aruba outdoor AP model and renders the AP susceptible to failure from lightning induced surges Rain: The wireless bridge or mesh link is weatherproofed against rain.

    Proper weatherproofing is not a fast process. Set aside ample time to complete the steps outlined below.  When wrapping, make the each layer of tape as flat as possible. Wrinkles and folds in the tape create  places for water and moisture to gather. Aruba MSR4000 Wireless Mesh Router | Installation Guide...

  • Page 20: Mounting Assembly

    Installing the MSR4000 The MSR4000 can be installed on a wall or attached to a pole. Pole diameter must be 40 to 60 mm at the position where the MSR4000 will be mounted. The following section describes how to attach the necessary hardware to the router and how to mount the router in the selected location.
  • Page 21 {M6 x30 bolt, flat washer, spring washer}x2 {M8 x110 bolt, flat washer, spring washer}x4 You can mount the MSR4000 on a pole with 96mm diameter using M8 x150 long bolts (not provided in the box shipped with MSR4000). Installing the MSR4000 on a Pole 1.

For example, if the antenna needs to connect to Radio 1 on MSR4000, the RF cables from antenna need to connect to the two antenna interfaces (Radio1) as shown in...
  • Page 27: Connecting The Ethernet Cable

    Connecting the Ethernet Cable To ensure that MSR4000 maintains Ethernet connectivity and Power over Ethernet (PoE), you must use the included weatherproof connector kit and install it using the steps below. Failure to use the included weatherproof connector kit can lead to connectivity and PoE issues.
  • Page 28 The Ethernet cable and power cable need proper drip loops. Drip loops prevent water from entering the router through the connectors. It is recommended to fix the Ethernet cable near the MSR4000 side to the wall or the pole. This is to ensure that the weight of the cable does not affect the RJ45 connector.
