Troubleshooting Hardware Problems
Determining Operating Status
5-33
Four levels of tests are supported; not all cards support all levels of tests. Table 5-34 lists these levels, the
types of tests performed, and the components for which the tests are supported.
A session log stores the latest results for each card in main memory and also on the internal-storage device
for low-level software; a history file stores the results for each session for the last 100 sessions on that
internal-storage device.
You can display partial test results while the tests are in progress; a notification message is displayed when
the session is complete. To view the results, use the
show diag
command with the
on-demand
keyword in
any mode. You can display the latest results for a card from the log or the results for one or more sessions
from the history file.
Initiate an ODD Session
Table 5-35 lists the available parameters for an ODD session.
Table 5-34
ODD Tests
Level
Components
Tests
1
All
Duplicates the tests of the power-on diagnostics; runs in 5 to 10 seconds.
2
Standby controller
card, traffic cards
only
Includes level 1 tests; tests all onboard active components in the line interface module (LIM) of the board,
including memory, registers, PPA DIMMs and SRAM, PPA and other onboard processors; runs in 5 to 10
minutes.
3
Traffic cards only
Includes level 2 tests; tests and verifies the card data paths for the entire card with internal loopbacks;
runs in 10 to 15 minutes.
4
Traffic cards only
Includes level 3 tests; tests the entire card using external loopbacks; must be run on site with external
loopback cables installed; runs in 10 to 15 minutes.
Note
If you are connected to the system using the Ethernet management port, you must enter the
terminal monitor
command (in exec mode) before you start the test session so that the
system displays the completion message. For more information about the
terminal monitor
command
, see the
Basic System Operations Guide
for the SmartEdge OS.
