Power-On Self Test Failure
At power-on the Modem will carry out a number of tests to confirm the operational
integrity of various onboard components. If segments 1 to 29 (excluding segment 6 the
“IPW” logo) are illuminated following power-on then the Modem is indicating a particular
test has failed.
If a segment/segments is/are illuminated for a period of 5 seconds followed by the
modem returning to normal operation then this indicates a warning that a non-critical
self-test has failed but will not hamper the operational capability of the modem.
If a segment/segments is/are constantly illuminated following power-on then a critical
self-test has failed and the modem will not be initialized in order to protect against
possible damage to onboard components.
In both scenarios it is recommended the user switch off the modem and contact
your
Service Provider for
Technical Support
.
Software Upgrade Warning
If the Modem display, in normal operation, flashes on and off at an interval of 2 seconds
then the network is informing the user that a Modem software upgrade is required.
Please refer to Appendix C for details on performing software upgrades
.
