Verifying switch fabric module operation
To verify switch fabric module (SFM) operation, complete the following steps.
1. Check the LEDs on the fan module, management module, and SFM front panel. Since the SFM is behind the fan module,
LEDs are provided on the fan and management modules to check SFM status. For information about interpreting LED
patterns, refer to
Interpreting switch fabric module LEDs on page 84.
2. Enter the following commands and note any error conditions:
• show chassis
• show system
• show environment sensor
• show environment temp
NOTE
For details about these commands, refer to the Extreme SLX-OS Monitoring Configuration Guide for SLX 9850
