2-10 Asynchronous Transfer Mode (ATM) Module Installation and User Guide
Installing or Replacing an ATM Module
Verifying the Module Installation
After you have installed the ATM module and connected the fiber optic cables, verify
that the I/O module is working correctly. Check the LEDs on the front panel of the I/O
module and use the command-line interface (CLI)
show slot <slot>
command to
display slot-specific information about the newly installed module.
LED Indicators
When the ATM module and its ports are configured and operating normally, the
front-panel LED indicators should appear as follows:
• STATUS LED indicator: green blinking
• DIAG LED indicator: off
• Port status LED indicators (per port):
— Green: The link is operational.
—
Green blinking: The link is disabled.
— Amber blinking, returning to green: There is activity on the link.
— Amber blinking: The link is down (SONET error).
— Off: No signal was received.
Displayed Slot Status Information
Assuming that there are no other problems with the ATM module, the command
show slot n
(where n is the number of the slot where you installed the module) will
show that ExtremeWare has detected the module and set it to the OPERATIONAL state.
As the module progresses through its initialization, the
show slot n
command will
show the GPP subsystem change state to OPERATIONAL, and then each of the network
processors will change state to OPERATIONAL.
Troubleshooting
This section describes how to isolate module-specific problems and determine when it
is appropriate to remove and replace an ATM module. This section includes information
on the following topics:
