Status • Green: Operationally up and administratively up.
• Amber: Operationally down but administratively up.
• Amber (blinking): Qualified, but previously failed.
• Unlit: Not operational, shutdown, or administratively down.
M/S Ctl Master/Slave SF/CPM designation:
• Green: Indicates that the SF/CPM is designated as the primary SF/CPM
in a redundant system.
• Green (blinking): Indicates that the SF/CPM is operating as the
secondary SF/CPM in a redundant configuration.
M/S Ref Master/Slave clocking reference designation:
• Green: Indicates that the SF/CPM is designated as the primary clocking
reference in a redundant system.
• Green (blinking): Indicates that the SF/CPM is operating as the
secondary clocking reference in a redundant system.
• Unlit: Clock not initialized.
Note: The clock is only required for SONET and/or 10GbE WAN
operations.
Timing The Timing LED indicates system status and quality.
• Green: Locked (operational state).
• Green (blinking): Clock in (internal) holdover state.
• Amber (blinking): Clock in free running state. The SR is attempting to
get a lock. When in the free running state, the timing of the SR can drift
and is not reliable. The preferred state is locked.
• Unlit: Clock not initialized.
