Autofib 2 Fault - Reboot the Crate (TO)

Description

Autofib has two network connections. The connection on the rear of the crate connects to the utility network. This is used for the ICL system to issue commands to Autofib. The connection on the front of the crate connects to the standard computer network of the observatory. This connection is used to download software files for the Autofib VME crate.

If the network connection to the utility network is broken then ICL will not be able to send commands to Autofib. A quick check of this connection is to check the utility network with a VT220 display plugged into an NIU info port. Pressing <3> will show all the equipment on the network. Autofib should be amongst these. If not, then there is a problem with the utility network that requires further investigation.

If the network connection to the conventional network is broken then autofib will be unable to download files from the network. This will generate errors in ICL relating to files not available, I/O errors. To check this connection, telnet to autofib. If this does not work then the problem with the conventional network will require further investigation.

Try

If you suspect that there is a communication problem try the following solutions.
 

  • Try a softreset. (Only if you have the system password for the AF2 crate)
    1. Locate the engineering terminal on Taurus.  It may be minimised.
    2. If it isn't open then start it by right clicking the mouse button and selecting AF2 Tip session from the Programs menu.
    3. Note  - only one instance can be opened at any time.
    4. Make sure that there is a `Autofib OS/9 >' prompt.  If there is an `Engineering command >' prompt type quit.
    5. Then type 'login', type 'system' as the username and then the system password.
    6. Then type 'os9_reboot' this will reset the crate.
    7. This should solve most network problems.
  • Try a hardreset
    1. Check the two network connectors are connected to the crate.
    2. Reboot the af2 crate by pressing the reset button on the back of the crate (or power cycle the crate).
    If this doesn't work then try the General Recovery Procedure.  If you have already tried that either contact the Duty Engineer or the appriopriate AF2 Expert.
