The following additional conditions apply:
•After module power up, the CM/FM STATUS LED will remain red until diagnostics begin then will blink green.
•After module power up, the ACTIVE/STANDBY LED will initially indicate Standby state until it registers either the Active or Standby state.
•When a link is not present, the Speed LED will be off.
IOM LEDs
All IOM cards include one Status LED for the card and Transmit and Receive or Link/Activity and Speed LEDs for each port. Refer to the Quick Reference card for your IOMs for more specific LED information.
LED definitions for the Status LED and the TX/RX LEDs for single‐speed Ethernet ports are given in Table 3‐4.
