2. The Diagnostics menu appears. Select the submenu option as shown in
Table 7-1 and press Return.
Table 7-1. Diagnostics Options
Selftest D-A
Displays the results of the last disruptive selftest of the DSL card. This selftest is only
performed on power up of the system or a reset of the card. Each subsystem
(processors, memory, and interfaces) reports pass or fail. If all subsystems pass, the
card has passed selftest. If a subsystem fails, reset or replace the card.
You can determine when the selftest occurred by reading the elapsed time since the last
reset on the card.
Alarms (Card Alarms) D-B
Displays all active card alarm conditions. Major alarms include Selftest failure,
Processor failure (sanity timer), and DSL or Ethernet port failures. Minor alarms include
Config Error (configuration has been corrupted) and threshold exceed for DSL margin or
Link Down events.
DSL Packet Echo Test D-C
Gives the user the ability to conduct a nondisruptive packet test between the DSL card
and Hotwire SN endpoint. Test packets are sent to the SN at 10 percent of the line rate
and echoed back to this card, where they are counted and checked for errors. The
running time of the test can be specified and the test will continue until the specified
time has elapsed or the test is stopped.
Results include packets sent, valid packets received, errored packets received, errored
seconds, and elapsed time of the test.
NOTE: You can specify the DSL port number but only one port can be entered at a
time.
SN Selftest D-D
Gives the user the ability to perform a power-on SN selftest. A port number can be
selected to perform the test.
NOTE: Entering yes in the Reset SN field will temporarily disrupt the data path on
the specified DSL port while the SN resets.
