Management Interface Module LEDs

The Management Interface modules have six LED yellow over green indicator pairs, which show
critical system module statuses.
The six pairs of LED indicators are a mirror of the LEDs that appear on the front of the chassis:
• System-wide status (Table 5 -7)
• Management Module status (Table 5 -8)
• Power Supply 1 and 2 status (Table5-10)
• Fan Tray 1 and 2 status (Table 5- 9)
In addition, the Ethernet Management port RJ-45 connector on the Management Interface module has
built-in status LEDs for link and traffic status.
