The Status LED/Button on the rear of the chassis changes to AMBER when any of the Front Panel iconic
indicators shows AMBER. When the chassis/MM is in Identify State, the combo Status LED/Button shall
always blink BLUE and override any other Status LED state.
IO Module LED Behavior
I/O Modules (IOMs) are inserted in the rear of the chassis and support a two-stacked arrangement of LEDS:
Top = AMBER/GREEN, Bottom = BLUE.
Figure 2a – Typical Fab A/B IO Module: Power/Status LED on the top and Identification LED on bottom as shown by
red highlights.
Figure 2b – Typical Fab C IO Module: Power/Status LED on the top and Identification LED on bottom as shown by red
highlights.
The LEDs support the following functions

The green LED behavior can be overridden to indicate fabric mismatch. In case there is a fabric mismatch,
green LED will blink for 2.5 seconds and then stay lit.
