0094)> 3-8


Action SSB401, SEC402/SEC401 or ESB bus failure may be considered as an errorcause. Take appropriate action in the following:

• Check to see if the ESB bus cables are connected correctly. Check for in-correct connection or bad connection of the cables, or check the termina-tors of the bus.

• Check to see if one SSB401 is causing a bus error of the entire buses ac-cording to the following procedure.Pull out the ESB bus connector of each SSB401 that connects to the cor-responding bus, one by one, from the node.Wait for two to three seconds, and if “Recover” is not printed, insert theESB bus connector again, and pull the bus connector of the next node.If “Recover” is printed, the bus connector of the SSB401 that was pull outat that time is faulty, so replace the SSB401.

• If no recovery was made even after the bus connectors of all nodes werepulled out, the SEC402/SEC401 may be faulty. In such a case, replacethe SEC402/SEC401.

• If no recovery was still made, press the [START/STOP] button on theCPU module’s front panel on the control side twice, and switch the controlright of the CPU module. Replace the CPU module after restarting.

If the bus does not recover even after these operations, the error may be rela-ted to the ESB bus cable (T-shape connector and so on). Replace the ESBbus cable.

Note This message is generated if all the I/O nodes, excluding the CPU node, be-come abnormal.However, if a system contains Optical ESB Bus Repeater module, when all theI/O nodes directly connected to/from SEC402/SEC401 (i.e., the I/O nodes notconnected via Optical ESB Bus Repeater module), become abnormal, but theI/O nodes connected via the Optical ESB Bus Repeater module are normal,this message is not generated.

• Connection route to the ESB Bus Interface module becomes abnormal.


0094)> 3-9


• For the I/O nodes that are connected via Optical ESB Bus Repeater mod-ule, the Optical ESB Bus Repeater module related hardware such asmodule or Fiber-optic cable may have problem.

Action If an I/O node routed through the Optical ESB Bus Repeater related devicesbecomes abnormal, the erroneous device can be identified according to thecontent of the messages or the LED status so as to replace the damaged de-vice. If all the I/O nodes routed through the Optical ESB Bus Repeater relateddevices become abnormal, the error may have occurred in the Optical ESBBus Repeater module related hardware such as module or Fiber-optic cable.Moreover, if the Optical ESB Bus Repeater modules are mounted in theSNT10D, the error may be caused by the failure of a power supply module ofSNT10D unit.
