Standard Configuration Options for MD4000 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  Number of active radios operating on the mesh node or mesh engine. Standard board has 4. [Image]
  3  For MD4000 series the number of radios used in this configuration- could be 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 Safely. 
  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 (Item 5 above)
 
{0 } Model 4350, has three radios: one 2.4GHz service radio in slot 2 and 5.8 GHz uplink and downlink in slots 0,1. 

{2,  4  } Additional downlinks enables more bandwidth dispersion from a central Ethernet link.
Models 4452 and 4454  have 4 radios. They support two and four backhaul sub trees respectively. 
 
{5 } denotes a mobility Scanner. A passive listening radio housed in slot 3 scans backhaul uplink to select next best candidate parent mobile mesh node's downlink. Models 4455, 4355, 4325 are scanner equipped 4 and 3 radio modules.
  
{8 } Model 4458 supports up to three 2.4GHz or 4.9GHx Access Points (AP) radios service clients with sectored antennas. Two variations are possible, 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. 
Please use the MD4000 numbering scheme to discuss your custom configuration with our application engineers.
Other options (e.g. GPS, 3.3VDC boards) are not part of the configuration scheme. They are ordered as separate items.

Notes for OEM Customizations

1. All models support 400 mw 802.11a/b/g Mini-PCI AtherosTM based field replaceable radio cards. See: Cover Removed 
2. All models 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: MD4000  Maintenance
