Interpreting Nonport-Side LEDs

The RUCKUS ICX 7550 contains the following LEDs on the rear panel:

  • Power supply LEDs: Two single-color status LEDs (green) on each installed power supply
  • Fan assembly LEDs: One bicolor status LED (green and amber) on each installed fan assembly
  • Management port (RJ-45) LEDs: One for link/activity and one for speed. Each of these LEDs is green.
Note: The external reference clock input is not included in the ICX 7550-24, ICX 7550-48, ICX 7550-24P, and ICX 7550-48P models.
