5. Enclosure (DCE-HC-ASSY)

The number of and type of radios, RF cabling, surge arrestors and antennas depends on the specific configuration, but all of these can essentially be mixed and matched.

2 Assembly Instructions

2.1 Enclosure

2.1.1 Tools/supplies required

• two adjustable spanners (small or medium)
• philip's screwdriver
• hammer (possibly)
• silicone sealant
• Enclosure (DCE-HC-ASSY)
• pigtails
• ethernet pass-through header

2.1.2 Enclosure Assembly

These often come pre-assembled, so you may not need to do this.

1. Put on the pigtails
   1. Unscrew the pigtail nut, remove the nut and lock-washer, making sure that the black rubber washer remains in place
   2. Coat the washer with silicone sealant
   3. thread the the pigtail through the enclosure hole.
      • You may need to puncture the hole using a screwdriver or chisel and hammer
   4. coat the joint between the enclosure and the pigtail screws with silicone sealant.
   5. put on the lock washer and bolt
   6. hold the pigtail in place with spanners, on the flat part of the outside, while turning the bolt with another set of spanners. Tighten.
2. Put on the ethernet pass-through header
   1. This process is similar to the pigtails
   2. Unscrew the nut from the ethernet pass-through header
   3. Coat the insider surface of the header with silicone sealant
   4. Thread the header through the board
   5. Coat the joint between the enclosure and the pass-through with sealant
   6. Screw on the nut
   7. This time, use one spanner on the inside 'nut' and one on the outside bolt.
      • Be careful you don't strip the plastic threads on the pass-through: it's not very strong!

2.2 Board Description

2.2.1 Wireless Card slots

There are two MiniPCI slots on the router, each of which can accept a wide variety of MiniPCI WiFi radios. Our long distance networking software is designed to work with cards using Atheros chipsets.

Each minipci card has a notch which mates with a protrusion on the slot, ensuring that the card is inserted in the correct position. Each card should be inserted firmly, at an angle, and then gently pressed down to be parallel with the main board of the router (picture). When the card is inserted properly, two notches on the side of the MiniPCI cards will click into two corresponding latches. If the latches do not line up the the notches, you probably have not fully inserted the card. Carefully try again, with the card at an angle again.

If you have one card installed, it will show up as the "ath0" interface on the router. If two cards are installed, ath0 will be the card on the right.

2.2.2 Compact Flash Card

Persistent storage for the routers is provided by a CF card, which is usually 512MB or larger. This card has the operating system, configuration and logs stored on it. Detailed instructions for installing the operating system on the card can be found at Tierlinux.

Follow the installation instructions for the operating system, and insert the flash card into the slot on the board (picture).

2.3 Mounting the board in enclosure

This process is slightly tricky because there is not a lot of space in the enclosure, and the ethernet passthrough in particular is difficult to get exactly right.

1. Insert the ethernet connector from the ethernet passthrough into the ethernet POE ethernet jack on the router (picture)
   • Make sure the pass-through is connected to the POE-in ethernet jack, or you will fry the ethernet controller, and possibly the rest of the board (we've done it).
   • Make sure that the cable loops around once, as shown in the picture
2. insert the router into the enclosure, underneath the pigtails and ethernet passthrough
   • be careful not to squish the ethernet cable too much, or you will crimp it and might cause damage or errors. Some 'squishing', however, is inevitable.
3. screw the router into place with the four mounting screws. Note that these screws ground the router to the enclosure
4. insert the minipci cards if you have not already
5. attach the pigtails to the wireless cards

Once you have tested (see below), and are ready to do the outdoor installation, you should seal the joint between the cover of the enclosure and the enclosure body with silicone sealant.

3 Testing

3.1 Connect with PoE

Warning: be very careful about which jack goes to the router, since if you plug the POE out from the POE injector into your laptop or switch, you will probably fry it

1. Plug a straight ethernet cable from the POE injector's "Data + VDC output" jack into the router.
2. Plug a crossover ethernet cable from the POE injector's "Data Input" jack into your laptop, or a straight ethernet cable into a switch
3. Plug the power cable into the injector and into the wall

3.2 Booting

Under normal conditions, you will need to wait until the ethernet driver in the operating system loads to ping the device, and you will need to wait until the SSH daemon starts up to log in.

The default IP address for the device is:

• eth0: DHCP client
• eth1: 10.0.99.1/24: DHCP server

You will need to configure your own device to be on these subnets in order to access them. The default root password is "soekris". If you can log in, then its time to configure the device (link)!

If you are having trouble, try attaching to the console, which unfortunately involves removing the device from the enclosure (link).

4 Other

4.1 Upgrading BIOS

• Connect on serial port
  • Use baud rate:38400, 8N1 to look at the BIOS messages

• Check the BIOS version: Enter BIOS setup by pressing S during memory test. It will show the BIOS version

• Download the latest BIOS from the PC Engines. The BIOS files are: for alix.2c send alix2c.upd, for alix.3c send alix3c.upd.
  • For ALIX 2/ALIX 3: http://www.pcengines.ch/alix2.htm
  • For ALIX 2/ALIX 3: we need at least version 0.99b or above.
  • README is included in the downloaded zip file.

• Upload the new BIOS: Enter BIOS setup by pressing S during memory test. Then press X to start transfer, and start a X-Modem 1K (CRC) upload / send in your communication program and select the right BIOS file. And reboot.

• Once connected to the BIOS, you can change the default baud rate also to 19200, 8N1 which is used by the kernel later.
