Assembling the LV-67C based Node

The assembling of new LV-67C based orbit node can be broken down into 4 tasks.

1. Flash The LV67-C bios
2. flash and install the CM3 module
3. Install Motherboard / Power supply

Flash The LV67-C bios

You will need the USB Thumb drive which has the bios and the utility to boot the motherboard from.
You will need a Video Card to flash the bios, the motherboard does not have one.

1. Hit DEL key to get into BIOS
2. change boot settings to boot of the USB Thumb drive.
3. Reboot the Machine.
   
4. Boot into the DOS shell.
5. Change directory to bios
   
6. Run plash16.exe bios.bak

How to flash and install the CM3 module

Flashing the CM can be done one of two ways

• Flashing the CM over FTP ===
  1. Plug the CM3 into the network and power it on
  2. Find the IP address of the CM3 (whether it be already in DHCP or randomly assigned)
  3. ftp to the device

     ftp xxx.xxx.xxx.xxx
     

  4. having some image "REV_X_Y_Z.rom.gz" use the 'put' command to flash the CM

     put REV_X_Y_Z.rom.gz xport_ar.rom.gz
     

     • if the image name is already xport_ar.rom.gz then there is no need to rename it. the image must be transfered to the device under than name or it will not be recognized as new firmware.
  5. The CM will not write the file and flash itself
• Flashing the device over serial
  1. Use a computer with "Lantronix Device Installer" installed on it.
  2. Go to 'Tools'→'Advanced'→'Recover Firmware' (or simply the F8 key)
  3. Configure the options, and hit OK to load the image
     1. Choose the COM port being used
     2. Select "Xport AR A1" as the device
     3. Make sure that the "Erase all flash" option is checked
     4. Enter the path of the image to be loaded

4. The program will prompt you to power off the device, you can just ignore this and hit next
5. The serial recovery will have started, but you must still power cycle the device before the transfer begins, either hit the reset button on the CM or just pull and reapply the power to the CM.

How to Assemble the Case

Components you will need to assemble a case:

System:

• 1 x LV-67C mother board
• 1 x 270 Watt power supply (Part Number FSP270-60LE)
• 1 x Sata Hard drive
• 1 x CM3
• requsite cables for CM3 ILYA FIX ME
• 1 x sata cable
• 1 x serial cable (from cm3 to motherboard)

Case:

• 1 x case Chassis (U shaped chassis)
• 1 x rear face plate cap (Folds over the U)
• 1 x front face plate (has cm3 punch outs, and hard dive mount holes)
• 1 x top cover (has Circular CPU ventilation holes)
• 1 x motherboard face plate (supplied with the motherboard)
• 1 x Velcro wire strap

Fasteners:

• 4 x 6-32 ½" 100 degree screws for securing the motherboard
• 12 x 6-32 ¼" 100 degree screws for fastening the case together and securing the power supply to the case
• 1 x 6-32 ¼" pan head screw for fastening the power supply.
• 3 x 6-32 3/16" 100 degree screws for CM mounting to chassis
• 3 x 6-32 9/32" hex stand offs for CM mounting
• 3 x 6-32 3/16" pan head screws for CM mounting
• 4 x M3 5mm stand offs for hard drive mounting
• 4 x M3 5mm screws for hard drive mounting

Wireless Adapters:

• 1 x minipcie Intel Wifi + Wimax 6250 card
• 1 x pcimcia Atheros Ar5212A 802.11 a/b/g wireless card
• 1 x minipice ½ height adapter
• 2 x minipice adapter screws (supplied with adapter)
• 3 x ufl-sma pig tails (9in)

Main U chassis:

1. Assemble the mother board:
   1. Attach the minicpie and pcimcia cards to the mother board.
      1. The mother board should come out of the static bag with cpu and memory installed.
   2. Connect all the pig tails and route the wires to the right side (facing the rear) of the motherboard.
   3. The Mother board should be aligned with the screw holes so that the headers point away from the vent hatching on the u channel.
      1. The orientation of the screw holes on the chassis is very specific.
      2. While aligning the mother board route the sma header from under neath the motherboard to the right behind the standoff.
         1. This keeps the sma-ufl wires away from the cpu fan.
   4. Once aligned use the ½" screws to secure the mother board.
2. Install Power supply:
   1. The power supply sits in the open area to the left (looking at the rear) of the mother board.
   2. Separate the yellow/black 4 pin plug from the rest of the cables
   3. Slide in the power supply into place, while threading the black/yellow 4 pin header below the cpu heatsink.
      1. It's important to thread the wire below other wise it will get stuck in the cpu fan.
      2. The power supply will be secured to rear face plate when it is installed.
      3. The power supply is not attached to the main U chassis however it must be inserted before installing the rear cap.
   4. Connected the 24 pin atx power headers.
   5. Connect 4 pin plug it to the extra power header behind the PS/2 keyboard/mouse riser.
3. Assemble the rear cap:
   1. Pass one end of the serial cable through the mother board face plate opening
   2. place the cable in the cut out on the top of the face plate opening.
   3. Attach the mother board face plate to the opening on the rear face plate cap, locking the serial cable into the designated opening.
      1. The face plate should be mount so that it is open on the right side (to allow for a expansion card) and closed on the left (as close to the power supply opening as possible).
4. Mounting the rear cap on the U channel Chassis:
   1. Fasten the rear cap with 2 of the 6-32 ¼" 100 degree screws on the bottom of the U chassis.
   2. Use two of 100 degree screws and attach the bottom holes power supply to the rear cap.
   3. Use the 6-32 ¼" pan head screw to fasten the top of the power supply (near the 3 prong power header) to the rear cap.
   4. Bolt all the sma headers to the face plate. The header position convention used is:
      1. Header 1 of the wimax card goes to the left most (closest to the power supply) hole.
      2. Header 2 immediately to the right of header 1.
      3. WiFi header of the 802.11 card goes to the right most hole.
5. Mounting the CM:
   1. Attach the 3 6-32 hex stand offs to the cm card with the 3 6-32 pan head screws
   2. thread the other end of the serial cable between the 3 stand offs
   3. align the 3 stand offs with the 3 triangle oriented holes on the front left corner of the top of the U chassis.
   4. use the 3 3/16" 100 degree screws to attach the cm to the U chassis
6. Wiring the CM:
   1. ILYA FIX ME
7. Attach and Wire the hard drive:
   1. attach the M3 5mm hex stand offs to the hard dive using the bottom holes.
   2. Align the female end of stand offs with the holes on the right side of the front face plate (facing front)
      1. The face plate should be oriented so that the cm holes are in the upper left corner.
      2. The drive should be on the "inside" of the chassis and sata header should point to the left (towards the center of the case).
   3. Fasten the disk, stand off assembly to the face plate with the M3 5mm pan head screws.
   4. Attach power and sata cables to the drive. 1.When attaching the sata cable to the mother board, use the header closest to the CPU (sata1)
8. loop the velcro strap through the holes on the bottom:
   1. Tie down all the loose wires. 1.This prevents stray wires from getting to close to the cpu fan.
9. Mount the rear face plate:
   1. Use the three 6-32 ¼" 100 degree screws to attach the front face.
      1. use only the 2 side and bottom screw holes
      2. the top of the face plate will be attached to the top cover
10. Attach the Top Cover
    1. Use the remaning screws to attach the top cover.
    2. The rear of the top cover should go below the cap.
