Running Diagnostics On I/O And Management Modules; Observing Led Behavior During A Diagnostic Test - Extreme Networks ExtremeWare XOS Guide Manual

Status Monitoring and Statistics
Application-Specific Integrated Circuit (ASICs) and Central Processing Unit (CPUs) operate as
●
required
Data and control fabric connectivity is active
●
External ports can send and receive packets
●
Sensors, hardware controllers, and LEDs are working correctly
●
NOTE
Before running slot diagnostics, you must have at least one MSM installed in the chassis.

Running Diagnostics on I/O and Management Modules

If you run the diagnostic routine on an I/O module, that module is taken offline while the diagnostic
test is performed. Traffic to and from the ports on that I/O module is temporarily unavailable. Once the
diagnostic test is completed, the I/O module is reset and becomes operational again.
If you run diagnostics on an MSM, that module is taken offline while the diagnostics test is performed.
When the diagnostic test is complete, the MSM reboots and becomes operational again.
To run diagnostics on I/O or MSM modules, use the following command:
run diagnostics [extended | normal] slot [<slot> | A | B]
Where the following is true:
—Takes the switch fabric and ports offline, and performs a simple ASIC and packet loopback
●
normal
test on all ports.
—Takes the switch fabric and ports offline, and performs extensive ASIC, ASIC-memory,
●
extended
and packet loopback tests. Extended diagnostic tests take a maximum of 15 minutes. The CPU is not
tested. Console access is available during extended diagnostics.
—Specifies the slot number of an I/O module. When the diagnostics test is complete, the
●
<slot>
system attempts to bring the I/O module back online.
NOTE
On the Aspen 8810 switch, if you run diagnostics on slots 5 and 6 with an MSM installed in those slots, the
diagnostic routine tests the I/O subsystem of the MSM. To run diagnostics on the management portion of the
master MSM, specify slot A or B.
A | B—Specifies the slot letter of the master MSM. The diagnostic routine is performed when the
●
system reboots. Both switch fabric and management ports are taken offline during diagnostics.

Observing LED Behavior During a Diagnostic Test

Whether you run a diagnostic test on an MSM or an I/O module, LED activity occurs during and
immediately following the test. The LED behavior described in this section relates only to the behavior
associated with a diagnostic test. For more detailed information about all of the MSM and I/O module
LEDs, see the Extreme Networks Consolidated XOS Hardware Installation Guide.
