Installing or Replacing a PoS Module
Verifying the Module Installation
After you have installed the PoS 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)
display slot-specific information about the newly installed module.
LED Indicators
When the PoS module and its ports are configured and operating normally, the
front-panel LED indicators should appear as follows:
• STATUS LED indicator: flashing green
• 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 PoS module, the command
(where n is the number of the slot where you installed the module) will
show slot n
show that ExtremeWare has detected the module and set it to the OPERATIONAL state.
As the module progresses through its initialization, the
show the GPP subsystem change state to OPERATIONAL, and then each of the network
processors will change state to OPERATIONAL.
When the GPP subsystem has completed its initialization cycle and the
subsystem state is OPERATIONAL, you can use the
command to check the results of the module's power-on self test
{<slot>}
(POST).
