2.11 Troubleshooting the RUGGEDCOM APE
Note
Line modules have the capability of being disabled. When disabled, a line module
does not consume power. If your RUGGEDCOM APE does not boot, ensure that it is
not disabled. If you are installing a RUGGEDCOM APE to act as a spare, you may wish
to disable the RUGGEDCOM APE to reduce power.
If the module-type is correct, the next most likely cause of failure is the module has
been disabled. Enabling the module in the chassis should allow it to boot.
If the module is correctly enabled, the next most likely cause of failure is a power
problem. The possibility of a power problem may be eliminated by making sure
the power supplied to the RUGGEDCOM APE is sufficient. For information about
power requirements, refer to the "Installation Manual" for your RUGGEDCOM RX1500
device.
If power is sufficient the syslog file should be examined for irregularities during the
boot. The last boot may have occurred some time in the past and may no longer be
recorded in the syslog. If this is the case, the module can be rebooted by disabling
it and re-enabling it. The syslog will then contain enties reflecting the RUGGEDCOM
APE boot.
If the syslog contains no messages reflecting an improper boot of the RUGGEDCOM
APE, return the RUGGEDCOM APE to Siemens.
The RUGGEDCOM APE should be returned to Siemens if its power LEDs remain dark
and all above debugging steps have been performed.
If the power LED lights up but the RUGGEDCOM APE does not boot, a monitor must
be attached to further diagnose the problems.
Problems with USB Ports
If problems occur when accessing devices (e.g. keyboard, storage media, etc.) via
USB, the most likely cause is the power consumed by all the devices on the USB
exceeds the maximum power capability of the RUGGEDCOM APE. This may be tested
by employing a powered USB hub. For information about the maximum power
available through the USB ports on the RUGGEDCOM APE module, refer to the
"Installation Manual" for your RUGGEDCOM RX1500 device.
