Software Configuration Options for Modular MeshTM Nodes
     

Explanation to Legend (numbers after black boxes refer to number markers above (1,2,3 ..)

  1  MD for Mesh Nodes or ME for Mesh Engines (OEM customers only, housing computer board in their own enclosures).
  2  Max Number of radios operating on the mesh node or mesh engine. Standard board has 4 slots. [Image]
  3  For MD4000 series the number of radios actually active in this configuration- could be 1,2, 3 or 4.
  4  Frequency band of the Uplink backhaul radio (in slot 0) : 5 for 5.8GHz, 2 for 2.4GHz, 4 for 4.9GHz Public Safety. 
  5  Model Configuration. Each of four radio slots may be configured to be uplinks, downlinks, service radio or scanners.**

  6  Frequency band for the uplink radio, in slot 0. Typically A (802.11a) B (802.11b), G (802.11g) or P (Public Safety)
  7  Frequency band for the downlink radio, in slot 1. Usually matches uplink but bridging across freq. bands is permitted. 
  8  Frequency band for the service radio, in slot 2. Generally B (.11b), G (.11g) or I (both b and g). 
  9  Frequency band for the service radio, in slot 3. Depends on the radio functionality. If none present, marked with "x".

Notes on MD4000 Model configurations (Marker # 5 above)
 
{ 0 }  MD4350-AAIx, has 3 radios: one 2.4GHz service radio in slot 2 and 5.8 GHz uplink and downlink in slots 0,1
MD4150-Axxx is a 4 slot board with one active radio servicing both uplink and downlink in slot 1.
MD2250-AA has two radios up/dn in slots 0 and 1. 
      
{ 1 } Model 4151-Axxx, 2151-Ax  is a single radio servicing both uplink and downlink in duty cycle mode. 

{ 2, 3, 4 }
Models 4452-AAIA and 4454-AAAA  have 4 radios. They support two and four backhaul sub trees respectively. 

{ 5 }
 
  "5" is reserved for mobility  Scanner active on the node. It may run on the uplink in duty cycle mode. 
          Or dedicated radio e,g. 4455-AAIA, 4355-AAxA, 4325-IIXI. See also  Single-Radio-Mesh-Options

{ 6 }
  
is 1+ 5= denotes a mobility Scanner running on a up + down link physical radio (e.g. 4151-axxx  in duty cycle mode)
         MD1156-A  and MD2256-AA, using Slot 1 for uplink, downlink and scanner in a 1+ 5 configuration

{7}
 
Specific for two radio units, see below with one radio providing the backhaul and the other 2.4GHz client access.

{8}  Legacy 4458 used three 2.4GHz or 4.9GHx Access Points (AP) radios service clients with sectored antennas. Two variations: one with one uplink and one downlink and two service radios: Model 4458-AAII. The second variation is where the downlink is not needed - as in edge nodes. In that case three slots are available for sectored antenna access. That configuration is Model 4458-AIII. Since A/I define frequency/use, we will now use 4454-AAII and 4454-AIII. .  

{9}
Not used.

Other options (e.g. GPS, 3.3VDC boards) are not part of the configuration scheme.
They are ordered as separate items and the mesh software discovers them at (re)boot time.

Standard Configurations, 4 slot radios, 4.9/5.8GHz Backhauls, 2.4GHz Client Access
  
1. 4250-AAxx: 2 radios, 11a uplink, downlink, slots 0,1. Intended as static backhaul, no AP for clients. Example

Notes for OEM Licensees

1. All models support 8011ac radios  in a 2, 4  or 6 slot board . See: Legacy Cover Removed 
2. All models can support three backhaul frequencies: 5GHz,(e.g MD4250),  4.9GHz (e.g. MD4240) and 2.4GHz (e.g. 4220).
3. All models are remotely configurable. Models may be field upgraded through the NMS. See: MD4000  NMS User Guide
4. All models support field replacement of radio cards. See: Legacy MD4000  Maintenance
5. All models support an internal GPS Radio. Must be factory installed, requires modifications to enclosure.
6. All models may be ordered in an Intrinsic Safe enclosure powered by 3.3VDC for mining safety.
7. All models support P3MTM Persistent Mesh. The Factory default setting is P3M disabled. User enables through the NMS.
